Long-duration stability of perovskite solar cells
US scientists have analyzed the impact of “seasoning” a formamidinium lead iodide solution with two-dimensional (2D) perovskites. They have found that the template improved the efficiency and durability of their solar cells.
Researchers build 24.4%-efficient perovskite solar cells with room temperature process
Researchers from the U.S. and South Korea have developed a method to make high-quality perovskite films at room temperature. The film was tested in a conventional perovskite solar cell architecture and the result was a power conversion efficiency of exceeding 24%.
Sunrise brief: California community solar in peril
Also on the rise: Technology-neutral proposed tax credit called ‘game-changing policy’. Less than 3% of farmland could power the Midwest. And more.
Shedding light on tandem perovskite solar cell progress
Perovskite tandem devices are at the front of the queue for commercialization but their characterization presents technical challenges.
Strategies to address thermomechanical instability of perovskite solar modules
A U.S. research team has investigated the thermomechanical reliability of metal halide perovskite (MHP) modules and cells in an effort to identify the best strategies to improve their stability under thermomechanical stressors. The scientists discussed, in particular, film stresses, adhesion of charge transport layers, and instability under light and heat.
Perovskites move into production
Perovskites remain a great hope for the future of the solar industry, once the possibilities of tunnel oxide passivated contact (TOPCon) and heterojunction PV have been exhausted. A look at the latest perovskite research shows that industry optimism is built on a strong foundation.
Researchers demonstrate 25%-efficient perovskite-cadmium tandem solar cell
University of Toledo researchers say the cell has a top perovskite cell with a transparent back contact made of indium zinc oxide and a commercially established cadmium telluride bottom device. They claim the champion tandem cell has the potential to reach a 30% efficiency.
