Inorganic perovskite PV cell hits 17.04% via fullerene-derivative interlayer
Researchers have achieved an efficiency boost of 15.44% to 17.04% in all-inorganic perovskite solar cells by incorporating a conductive fullerene-derivative interlayer between the perovskite and electron transport layers. They claim that this enhancement also improves thermal stability.
