Surrey Researchers Scale Low-Toxicity Perovskite Solar Cells

University of Surrey scientists publish a paper in Nano Energy detailing a significantly reduced-toxicity solvent system for perovskite solar modules. The method uses ethanol and renewable waste-derived solvents to replace hazardous chemicals like dimethylformamide. Researchers built mini-modules with active areas up to 11.5 square centimeters and reached power conversion efficiencies above 18%.
