摘要

Metal halide perovskite solar cells (PSCs) have attracted tremendous attention as an emerging photovoltaic technology due to their high efficiency,low cost and ease of fabrication from earth-abundant materials [1,2].The power conversion efficiencies (PCEs) have been rapidly boosted from 3.8％ in the pioneer's work to a certified 24.2％ nowadays in just ten years [3].The PCE breakthroughs in PSCs have mostly adopted full lead-based perovskites (APbX3) with bandgaps of 1.5-1.6 eV.
