Saudi Arabia’s KAUST Makes Breakthrough to Boost Solar Cell Efficiency and Durability

Researchers at Saudi Arabia’s King Abdullah University of Science and Technology (KAUST) have made a significant breakthrough in solar energy technology by developing a novel method to boost the performance and stability of perovskite silicon tandem solar cells.

The research team, led by Professor Stefaan De Wolf at the KAUST Photovoltaics Laboratory, discovered a way to significantly improve the efficiency and durability of these solar cells by introducing a chemical cation called tetrahydrotriazinium into the perovskite material, reported the Saudi Press Agency on Tuesday.

De Wolf said that these cells have undergone testing under conditions that replicate the intense light and heat of the Arabian Peninsula, which indicates that they can function effectively in environments with extreme climatic conditions where they might be required to operate.

Published in the journal Science, a leading peer-reviewed academic journal that covers a wide range of scientific disciplines, the method demonstrated that tetrahydrotriazinium strengthens the perovskite crystal structure by increasing hydrogen bond formation.

According to the journal, this enhancement substantially boosts power conversion efficiency and resistance to degradation caused by factors like intense sunlight and heat.

De Wolf emphasized the team's commitment to further enhancing the technology's performance and reducing costs through ongoing research. While the potential for commercialization is substantial, partnerships are essential to scale production and bring this innovative technology to market, he said.

This groundbreaking research represents a major step forward in developing affordable and sustainable solar energy solutions.

Rivian has temporarily suspended production of its commercial delivery vans used by retail giant Amazon.com due to a shortage of parts, a spokesperson for the electric vehicle manufacturer said on Friday.

Shares of the Irvine, California-based company were down 1.7% in premarket trading.

The production halt is the latest in a series of supply chain challenges for Rivian, which, like other EV makers, has grappled with significant production issues over the past two years due to supplier shortages, according to Reuters.

Amazon, Rivian's largest investor with a 16% stake, has ordered 100,000 electric delivery vans to be deployed by 2030. Last year, sales to Amazon represented approximately 19% of Rivian's revenue.

Amazon did not immediately respond to a Reuters request for comment.

"A part shortage has temporarily impacted our Electric Delivery Van (EDV) production. We expect to recover all missed production," the spokesperson said in an emailed statement.

The company did not disclose any information about the specific part and supplier in question, and also declined to comment on when the production stoppage began and if it has resumed.

The part shortage would not affect the production of other Rivian vehicles, including its R1S SUV and R1T pickup models.

Earlier this month, Rivian had maintained its production forecast and said that deliveries would be slightly lower in the current quarter after it shut down its factory in April for retooling and modifications.
