Engineers make a promising material stable enough for use in solar cells
Soft and flexible materials called halide perovskites could make solar cells more efficient at significantly less cost, but they are too unstable to use. A Purdue University-led research team, including Davidson School of Chemical Engineering faculty Dr. Letian Dou and Dr. Brett Savoie, has found a way to make halide perovskites stable enough by inhibiting the ion movement that makes them rapidly degrade, unlocking their use for solar panels as well as electronic devices. The results were published in the journal Nature on Wednesday (April 29).
