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.

Microsoft faces legal action in Britain over a claim that thousands of businesses using cloud computing services provided by Amazon, Google and Alibaba could be paying higher license fees to use Windows Server software.

Competition lawyer Maria Luisa Stasi filed a case at the Competition Appeal Tribunal on Tuesday, claiming that British businesses and organizations could collectively be owed more than 1 billion pounds ($1.27 billion) in compensation.

"Put simply, Microsoft is punishing UK businesses and organizations for using Google, Amazon and Alibaba for cloud computing by forcing them to pay more money for Windows Server," she said.

"By doing so, Microsoft is trying to force customers into using its cloud computing service Azure and restricting competition in the sector."

Separately, Britain's competition regulator is investigating cloud computing, a market dominated by Amazon's AWS, Microsoft's Azure and, to a lesser extent, Google Cloud Platform.

Microsoft's licensing practices, for example for its Windows Server and Microsoft 365 products, are part of its inquiry.

It is due to update on its investigation imminently.

Microsoft in 2020 introduced new license fees for running its software on major cloud providers.

The claim alleges it then used the fees to induce customers to use its Azure platform.

Data from the Competition and Markets Authority published in May showed Microsoft was winning customers at a significantly higher rate than other cloud providers since it made the licensing change.

The United States Federal Trade Commission last week opened a broad antitrust investigation into Microsoft, including its cloud computing business, according to a source familiar with the matter.

The FTC is examining allegations the software giant was potentially abusing its market power in productivity software by imposing punitive licensing terms to prevent customers from moving from Azure to competitive platforms, sources said last month.
