Perovskite-based tandem cells as clean photovoltaic conversion devices drive the transition to decarbonized energy. Recently in Nature, Tan and co-workers report a certified efficiency of 26.4%, a record-setting efficiency in all-perovskite tandem solar cells. High photocurrent density is achieved by ammonium cation passivation, addressing the short carrier diffusion length in thick mixed Pb-Sn narrow-bandgap subcell.

基于钙钛矿的串联太阳能电池向前驰骋

基于钙钛矿的串联电池作为清洁光伏转换装置推动了向脱碳能源的转变。最近在《自然》杂志上，Tan 和同事报告了 26.4% 的认证效率，这是全钙钛矿串联太阳能电池的创纪录效率。通过铵阳离子钝化实现高光电流密度，解决了厚混合 Pb-Sn 窄带隙子电池中载流子扩散长度短的问题。
