In this work, we explore the underlying reasons for scaling losses of perovskite solar cells, especially for the p-i-n configuration, and have successfully reduced this scaling loss to ~0.9%. With a comprehensive understanding of the underlying mechanisms, high-quality PSCs with a PCE of 20.3% for 2 cm2 devices and 19.8% for 6.8 cm2 mini-modules were obtained.
