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.

New Texas water plan does not consider data center growth, critics say

For the Future

A draft of Texas’ 2027 State Water Plan is drawing concerns from some water protection advocates who say it fails to account for one growing industry: data centers.

The plan, created by the Texas Water Development Board, will guide tens of billions of dollars in water development projects over the coming decades.

On Memorial Day, people packed Lake Travis to enjoy the water and sunshine while the lake remains near full capacity. But some advocates warn drought conditions could quickly return.

“Once we get into August, September, we'll be probably right back in the same drought situation,” said Mike Clifford with the Greater Edwards Aquifer Alliance.

The Texas Water Development Board released the draft plan in April. It recommends thousands of water projects carrying a projected cost of $174 billion over 50 years.

“We're not as shocked about the dollar amounts as some people are,” Clifford said. "To secure our water future, that's not an insane amount to ask for."

However, Clifford said his organization was surprised the draft does not specifically account for the growing impact of data centers, which can consume large amounts of water.

“If you leave the data centers out, it's not really a plan in our opinion. It's going to have to be changed and it's going to fall short,” Clifford said.

According to Data Center Map, Texas is currently home to 461 data centers.

Clifford argues the state should use projected future growth, not just historical data, when planning for long-term water needs.

“They're looking at the previous 10 years or 20 years or whatever, and we didn't have a lot of data centers in Texas,” he said.

Researchers at the the University of Texas at Austin estimate data centers could account for as much as 9 percent of Texas’ total water use by 2040, or potentially surpass the oil and gas industry that same year.

Houston startup strikes deal to develop hydrogen production plant in Canada

hydrogen partnership

Houston-based cleantech startup Vema Hydrogen has reached a tentative agreement with Canada-based CHARBONE Corp. to develop a hydrogen production and processing plant in Québec.

The deal would couple Vema’s production of engineered mineral hydrogen with CHARBONE’s purification, compression and distribution capabilities.

Engineered mineral hydrogen, also known as orange hydrogen, is produced underground by accelerating naturally occurring geochemical reactions in iron-rich rock formations, according to the journal Energy & Environmental Science.

“Across high-value markets — from aviation and maritime fuels to industrial gases — there is incredible demand for Vema’s low-carbon [hydrogen]. Now, more than ever, we need a pathway to deliver these low-carbon fuels,” Pierre Levin, CEO of Vema, said in a news release.

The project would enable Vema to expand into emerging markets like low-carbon maritime and aviation fuel, e-fuels and power generation. Incorporating CHARBONE’s capabilities, the agreement would also support Québec’s hydrogen supply chain.

“The market is demanding high-value industrial gases, and our customers need cleaner, more reliable supply. By pairing Vema’s [hydrogen] feedstock with our purification and distribution capabilities, we’re strengthening Québec’s position as a regional hub for next-generation hydrogen,” Dave Gagnon, CEO of CHARBONE, added in the release.

Vema said in February that it had completed drilling of its first two pilot wells in Québec, making them the world’s first pilot well for orange hydrogen. It’s the first time Vema’s technology has been used outside a lab.

“This pilot will provide the critical data needed to validate [our hydrogen] at commercial scale and demonstrate that Quebec can lead the world in this emerging clean energy category,” Levin said. “The quality of the rock within our core samples is exactly what we expected and is very promising for hydrogen yields.”

Shortly before Vema carried out the pilot drilling, it signed a 10-year deal with California-based energy technology company Verne Power to supply clean hydrogen for California data centers. Over the course of the 10-year agreement, Vema will boost annual production of orange hydrogen to more than 36,000 metric tons.

“There is a robust market for baseload power generation across the U.S., where data centers are straining the grid,” Levin said. “As we power California’s fastest-growing markets with clean hydrogen, we look toward expanding our hydrogen to markets globally and supporting AI-driven power hubs.”

Vema, founded two years ago, raised $13 million in seed funding in 2025.

“The energy transition and emerging uses of hydrogen have spurred demand for clean hydrogen,” Levin said in its funding announcement. “However, existing decarbonized hydrogen production methods simply don’t work — they are too costly and energy-intensive. Vema is here to change that. It’s time to unlock a new era of scalable, low-carbon hydrogen.”
