A groundbreaking Rice University lab has made further strides in its work to make harvesting light energy more efficient and stable.

Presented on the cover of a June issue of Science, a study from Rice engineer Aditya Mohite's lab uncovered a method to synthesize a high-efficiency perovskite solar cell, known as formamidinium lead iodide (FAPbI3), converting them into ultrastable high-quality photovoltaic films, according to a statement from Rice. Photovoltaic films convert sunlight into electricity.

The new process makes solar cells that are about 10 times more durable than traditional methods.

“Right now, we think that this is state of the art in terms of stability,” Mohite said in a statement. “Perovskite solar cells have the potential to revolutionize energy production, but achieving long-duration stability has been a significant challenge.”

The change come from "seasoning" the FAPbI3 with 2D halide perovskites crystals, which the Mohite lab also developed a breakthrough synthesis process for last year

The 2D perovskites helped make the FAPbI3 films more stable. The study showed that films with 2D perovskites deteriorated after two days of generating electricity, while those with 2D perovskites had not started to degrade after 20 days.

“FAPbI3 films templated with 2D crystals were higher quality, showing less internal disorder and exhibiting a stronger response to illumination, which translated as higher efficiency," Isaac Metcalf, a Rice materials science and nanoengineering graduate student and a lead author on the study, said in the statement.

Additionally, researchers say their findings could make developing light-harvesting technologies cheaper, and can also allow light-harvesting panels to be lighter weight and more flexible.

"Perovskites are soluble in solution, so you can take an ink of a perovskite precursor and spread it across a piece of glass, then heat it up and you have the absorber layer for a solar cell,” Metcalf said. “Since you don’t need very high temperatures ⎯ perovskite films can be processed at temperatures below 150 Celsius (302 Fahrenheit) ⎯ in theory that also means perovskite solar panels can be made on plastic or even flexible substrates, which could further reduce costs.”

Mohite adds this has major implications for the energy transition at large.

“If solar electricity doesn’t happen, none of the other processes that rely on green electrons from the grid, such as thermochemical or electrochemical processes for chemical manufacturing, will happen,” Mohite said. “Photovoltaics are absolutely critical.”

The Mohite lab's process for creating 2D perovskites of the ideal thickness and purity was published in Nature Synthesis last fall. At the time, Mohite said the crystals "hold the key to achieving commercially relevant stability for solar cells."

About a year ago, the lab also published its work on developing a scalable photoelectrochemical cell. The research broke records for its solar-to-hydrogen conversion efficiency rate.

Woodside Energy backs $12.5M clean energy accelerator for new technologies

howdy, partner

A global Australian energy company with its international operations in Houston has backed a new climatetech accelerator in partnership with Rice University.

Woodside Energy, headquartered in Australia with its global operations in Houston following its 2022 acquisition of BHP Group, has committed $12.5 million over the next five years to create the Woodside Rice Decarbonization Accelerator.

"The goal of the accelerator is to fast track the commercialization of innovative decarbonization technologies created in Rice labs," Rice University President Reginald DesRoches says to a crowd at the Ion at the initiative's announcement. "These technologies have the potential to make better batteries, transitistors, and other critical materials for energy technologies. In addition, the accelerator will work on manufacturing these high-value products from captured and converted carbon dioxide and methane."

"The Woodside Rice Decarbonization Accelerator will build on the work that Rice has been doing in advanced materials, energy, energy transition, and climate for many years. More than 20 percent of our faculty do some related work to energy and climate," he continues. "Harnessing their efforts alongside an esteemed partner like Woodside Energy is an exciting step that will undoubtedly have an impact far and wide."

Woodside, which has over 800 employees based in Houston, has been a partner at the Ion since last spring. Daniel Kalms, Woodside Energy's CTO and executive vice president, explains that the new initiative falls in line with the three goals of Woodside's climate strategy, which includes keeping up with global energy demand, creating value, and conducting its business sustainably. The company has committed a total of $5 billion to new energy by 2030, Kalms says.

"We know that the world needs energy that is more affordable, sustainable, and secure to support the energy transition — and we want to provide that energy. Energy that is affordable, sustainable, and secure requires innovation and the application of new technology. That's what this is about," he says.

"Of course collaboration will be the key," Kalms continues. "By working with researchers, entrepreneurs, leading experts and parallel industries, we can combine our capability to solve collective challenges and create shared opportunities. That's why we are excited to be partnering with Rice."

The accelerator will be run by Paul Cherukuri, vice president of innovation at Rice University, and Aditya Mohite, associate professor of Chemical and Biomolecular Engineering and Materials Science and Nanoengineering. Additional Rice professors will be involved as well, Cherukuri says.

"Success for us will not be papers, it will be products," Cherukuri says of what Woodside wants from the partnership. "We picked faculty at Rice in particular who were interested in taking on this charge, and they were all faculty who created companies."

Last fall, Rice announced a grant and venture initiative to accelerate innovation from Rice in the biotech space.

Houston research team develops breakthrough process for light-harvesting crystals in DOE-backed project

solar success

A team of Rice researchers have developed a breakthrough synthesis process for developing light-harvesting materials that can be used in solar cells to convert light into electricity.

Detailed in an October study in Nature Synthesis, the new process is able to more closely control the temperature and time of the crystallization process to create 2D halide perovskites with semiconductor layers of “ideal thickness and purity,” according to a release from Rice.

The process, known as kinetically controlled space confinement, was developed by Rice University chemical and biomolecular engineer Aditya Mohite, along with others at Northwestern University, the University of Pennsylvania and the University of Rennes. The research was backed by the Department of Energy, the Army Research Office, the National Science Foundation and a number of other organizations.

“This research breakthrough is critical for the synthesis of 2D perovskites, which hold the key to achieving commercially relevant stability for solar cells and for many other optoelectronic device applications and fundamental light matter interactions,” Mohite said in a statement.

Traditional synthesis methods for creating 2D halide perovskites, which have been shown to offer a high-performance low-cost way to produce solar cells, have generated uneven crystal growth when attempting to reach a higher n value. And uneven crystal growth can result in a less reliable material, while a high n value can result in higher electrical conductivity, among other benefits.

The study shows how the kinetically controlled space confinement method can gradually increase n values in 2D halide perovskites, which will assist in the production of crystals with a certain thickness.

“We designed a way to slow down the crystallization and tune each kinetics parameter gradually to hit the sweet spot for phase-pure synthesis,” Jin Hou, a Ph.D. student at Rice and a lead author on a study, said in a statement.

The process is expected to improve the stability and lower the costs of emerging technologies in optoelectronics, or the study and application of light-emitting or light-detecting devices, and photovoltaics, the conversion of thermal energy into electricity.

"This work pushes the boundaries of higher quantum well 2D perovskites synthesis, making them a viable and stable option for a variety of applications,” Hou added.

Houston universities have been making major strides relating to crystallization processes in recent months.

In September, the University of Houston announced The Welch Foundation awarded its inaugural $5 million Catalyst for Discovery Program Grant to establish the Welch Center for Advanced Bioactive Materials Crystallization. The center will build upon UH professor Jeffrey Rimer's work relating to the use of crystals to help treat malaria and kidney stones.

Over the summer, a team of researchers at UH also published a paper detailing their discovery of how to use molecular crystals to capture large quantities of iodine, one of the most common products of radioactive fission, which is used to create nuclear energy.

Rice University team breaks records with new sunlight-to-hydrogen device

big win

A team of Rice University engineers have developed a scalable photoelectrochemical cell that converts sunlight into clean hydrogen at a record-setting pace.

The lab led by Aditya Mohite, an associate professor at Rice, published the findings in a study in Nature Communications late last month, in collaboration with the National Renewable Energy Laboratory, which is backed by the Department of Energy. In it, the team details how they created a device that absorbs light, converts it into electricity, and then uses the electricity to split water molecules and generate hydrogen.

Austin Fehr, a chemical and biomolecular engineering doctoral student at Rice and one of the study’s lead authors, says in a statement that the device "could open up the hydrogen economy and change the way humans make things from fossil fuel to solar fuel."

The device has a high solar-to-hydrogen conversion efficiency rate of 20.8 percent, which has yet to be reached with this type of technology, according to a release from Rice. In addition to its speed, this device is groundbreaking because it uses low-cost metal-halide perovskite semiconductors to power the reaction.

“Using sunlight as an energy source to manufacture chemicals is one of the largest hurdles to a clean energy economy,” Fehr says in the statement. “Our goal is to build economically feasible platforms that can generate solar-derived fuels. Here, we designed a system that absorbs light and completes electrochemical water-splitting chemistry on its surface.”

To create the device the Mohite lab turned their existing solar cell into a reactor to split water into oxygen and hydrogen. However they continued running into issues with the semiconductors being "extremely unstable in water," according to Rice.

After two years of trials and errors, the team uncovered that by adding two layers of barriers to the semiconductors they were able to reach these record-breaking efficiency rates.

The team has also shown uses for their double barrier design with different semiconductors and for different reactions.

“We hope that such systems will serve as a platform for driving a wide range of electrons to fuel-forming reactions using abundant feedstocks with only sunlight as the energy input,” Mohite says in the statement.

The device joins another game-changing product shared in a Rice research study in recent weeks. Last month, a Rice University lab led by Haotian Wang, the William Marsh Rice Trustee Chair and an associate professor at Rice, shared their findings on how their simple plug-and-play device removes carbon dioxide from air capture to induce a water-and-oxygen-based electrochemical reaction.

Rice also recently opened registration for its 20th anniversary of Energy Tech Venture Day. Click here to register for the event on Sept. 21.

Texas could topple Virginia as biggest data-center market by 2030, JLL report says

data analysis

Everything’s bigger in Texas, they say—and that phrase now applies to the state’s growing data-center presence.

A new report from commercial real estate services provider JLL says Texas could overtake Northern Virginia as the world’s largest data-center market by 2030. Northern Virginia is a longtime holder of that title.

What’s driving Texas’ increasingly larger role in the data-center market? The key factor is artificial intelligence.

Companies like Google and Microsoft need more energy-hungry data centers to power AI innovations. In a 2023 article, Forbes explained that AI models consume a lot of energy because of the massive amount of data used to train them, as well as the complexity of those models and the rising volume of tasks assigned to AI.

“The data-center sector has officially entered hyperdrive,” Andy Cvengros, executive managing director at JLL and co-leader of its U.S. data-center business, said in the report. “Record-low vacancy sustained over two consecutive years provides compelling evidence against bubble concerns, especially when nearly all our massive construction pipeline is already pre-committed by investment-grade tenants.”

Dallas-Fort Worth has long dominated the Texas data-center market. But in recent years, West Texas has emerged as a popular territory for building data-center campuses, thanks in large part to an abundance of land and energy. Nearly two-thirds of data-center construction underway now is happening in “frontier markets” like West Texas, Ohio, Tennessee and Wisconsin, the JLL report says.

Northern Virginia, the current data-center champ in the U.S., boasted a data-center market with 6,315 megawatts of capacity at the end of 2025, the report says. That compares with 2,423 megawatts in Dallas-Fort Worth, 1,700 megawatts in the Austin-San Antonio corridor, 200 megawatts in West Texas, and 164 megawatts in Houston.

Fervo taps into its hottest-ever geothermal reservoir

heat record

Things are heating up at Houston-based geothermal power company Fervo Energy.

Fervo recently drilled its hottest well so far at a new geothermal site in western Utah. Fewer than 11 days of drilling more than 11,000 feet deep at Project Blanford showed temperatures above 555 degrees Fahrenheit, which exceeds requirements for commercial viability. Fervo used proprietary AI-driven analytics for the test.

Hotter geothermal reservoirs produce more energy and improve what’s known as energy conversion efficiency, which is the ratio of useful energy output to total energy input.

“Fervo’s exploration strategy has always been underpinned by the seamless integration of cutting-edge data acquisition and advanced analytics,” Jack Norbeck, Fervo’s co-founder and chief technology officer, said in a news release. “This latest ultra-high temperature discovery highlights our team’s ability to detect and develop EGS sweet spots using AI-enhanced geophysical techniques.”

Fervo says an independent review confirms the site’s multigigawatt potential.

The company has increasingly tapped into hotter and hotter geothermal reservoirs, going from 365 degrees at Project Red to 400 degrees at Cape Station and now more than 555 degrees at Blanford.

The new site expands Fervo’s geologic footprint. The Blanford reservoir consists of sedimentary formations such as sandstones, claystones and carbonates, which can be drilled more easily and cost-effectively than more commonly targeted granite formations.

Fervo ranks among the top-funded startups in the Houston area. Since its founding in 2017, the company has raised about $1.5 billion. In January, Fervo filed for an IPO that would value the company at $2 billion to $3 billion, according to Axios Pro.
