摘要

The power conversion efficiency (PCE) of single-junction perovskite solar cells (PSCs) has rapidly boosted to 25.2％ [1],approaching the Shockley-Queisser limit.A potential strategy to further elevate the PCE of single-junction PSCs is to fabricate all-perovskite tandem solar cells [2,3],which is composed of a wide-bandgap (1.7-1.9 eV) top sub-cell and a low-bandgap (0.9-1.2 eV) bottom sub-cell.
