Abstract Atomic layer-deposited tin oxide serves as an effective buffer layer in perovskite/silicon tandem solar cells due to its efficient charge extraction and sputtering tolerance. Nevertheless, its unavoidable chemical erosion effect of atomic layer-deposited tin oxide on perovskite requires thicker fullerene charge transport layers, leading to increased parasitic optical absorption.

Abstract Perovskite/silicon tandem solar cells have emerged as promising candidates for next-generation photovoltaic technology due to their ultra-high power conversion efficiency (PCE)1-3. However, the mechanical stress generated during repeated environmental stress cycles remains a critical challenge for flexible perovskite/silicon tandem solar cells, leading to interfacial delamination and device degradation.

Abstract Achieving highly ordered and uniformly covered self-assembly monolayers (SAMs) with optimal packing configuration on textured silicon substrates remains a critical challenge for further improving the efficiency of perovskite/silicon tandem solar cells (TSCs)1-3.
