Researchers from the Chinese Academy of Sciences, Soochow University, Taizhou University, Forschungszentrum Jülich, ChangZhou S.C Exact Equipment Co., Jietai New Energy Technology Co. and Yongjiang Laboratory (Y-LAB) have demonstrated an efficient and stable perovskite/silicon tandem solar cell using a new peak-selective passivation (PSP) strategy. Perovskite/silicon tandem solar cells (PSTSCs) are regarded as a highly promising next-generation PV technology, with current world-record efficienc
