photovoltaics

A Nature Energy paper from Nanchang University achieves 26.61% certified efficiency with cesium doping, while a private Chinese cell surpasses all single-junction silicon cells at 27.98%.

Swiss researchers set a new certified record of 30.02% efficiency for a triple-junction solar cell combining silicon with two perovskite layers, published in Nature.

Kyushu University and JGU Mainz researchers use a molybdenum-based spin-flip emitter to surpass the one-photon-one-electron limit, reaching 130% quantum yield with a theoretical ceiling of 200%.
