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.
