摘要
In recent years,the power conversion efficiency(PCE)for single-junction perovskite solar cells(PSCs)[1,2]has reached 25.7%,approaching the Shockley-Queisser limit(S-Q limit).Further enhancing efficiency is challenging.Tandem solar cells offer an effective way to further increase the efficiency beyond S-Q limit.Currently,perovskite/silicon tandem solar cells(TSCs)[3−5]have achieved a PCE of 31.3%[6].However,the complicated preparation processes and high cost hinder their commercialization application.In contrast,thin-film perovskite/organic TSCs have the advantages of solution processability,low cost,and flexibility,making them to be promising candidates for the next-generation photovoltaic technology.
