Scientists have found a new way to improve highly efficient solar cells by adding an extremely thin layer of cesium chloride during production. The method helped a perovskite-silicon tandem solar cell convert 30.3% of incoming sunlight into electricity. Perovskite-silicon tandem cells combine two light-absorbing materials. Silicon captures part of the sunlight, while a perovskite layer […] The post Tiny Seed Layer Helps Tandem Solar Cells Reach 30.3% Efficiency appeared first on Knowridge Science Report .
