Smoother perovskite films push triple-junction solar cells to 30.1% efficiency
Original: Smoother perovskite films lift three-layer solar cell efficiency to 30.1%
Researchers report that making perovskite films smoother has raised the efficiency of a three-layer, or triple-junction, solar cell to 30.1%, a new benchmark for this class of device. Reducing surface roughness helps the stacked layers convert more sunlight into electricity. The result fuels ongoing excitement about perovskite technology as a cheaper, potentially more efficient alternative to conventional silicon solar panels.
Why now: A reported efficiency milestone for perovskite multi-junction solar cells is drawing attention to advances in next-generation solar energy.
