Abstract

Abstract Monolithic perovskite/silicon tandem solar cells promise power‐conversion efficiencies (PCEs) exceeding the Shockley‐Queisser limit of single‐junction solar cells. The conformal deposition of perovskites on industrially feasible textured silicon solar cells allows for both lowered manufacturing costs and a higher matched photocurrent density, compared to state‐of‐the‐art tandems using front‐side flat or mildly textured silicon. However, the inferior crystal quality of perovskite films grown on fully‐textured silicon compromises the photovoltaic performance. Here, an anion‐engineered additive strategy is developed to control the crystallization process of wide‐bandgap perovskite films, which enables…
