NREL’s Perovskite Solar Cell Research

NREL SolarCells

National Renewable Energy Laboratory (NREL) researcher Mengjin Yang works with hybrid perovskite solar cells. He and researchers at Shanghai Jiao Tong University (SJTU) have devised a method to improve perovskite solar cells, making them more efficient and reliable with higher reproducibility. The scientists converted a low-quality perovskite film with pinholes and small grains into a high-quality film without pinholes and with large grains. Doing so boosted the efficiency of the perovskite film in converting sunlight to 19 percent. 

NREL is the U.S. Department of Energy’s (DOE) primary national laboratory for renewable energy and energy efficiency research. From scientific discovery to accelerating market adoption, NREL deploys its deep technical expertise and unmatched breadth of capabilities to drive the transformation of our nation’s energy resources and systems.
