Zusammenfassung:Semi‐Transparent Perovskite Solar Cells In article number 2302147, Weiyuan Duan, Kanghoon Yim, SeJin Ahn and co‐workers report a new internal degradation mechanism in semi‐transparent perovskite solar cells (ITO/SnO2/perovskite/Spiro‐MeOTAD/MoO3/TCO). When the hole‐transport layer surface is enriched with LiTFSI, Li diffuses into the MoO3 layer and results in continuous degradation of the device. Conversion of LiTFSI into stable lithium oxides (LixOy) improves both the efficiency and stability of the device due to effective mitigation of Li diffusion.
