Abstract

To achieve optimal optical performance and minimal reflection losses, a textured interface between perovskite and silicon sub-cells in perovskite-silicon tandem solar cells is needed. However, the perovskite solar cells fabrication method yielding the highest efficiencies, spin coating, is not compatible with the conventional random micro-pyramidal texture on silicon. This study focuses on creating periodic inverted micro-pyramidal textures in silicon through photolithography, reactive ion etching, and wet-chemical etching, enabling the deposition of fully textured perovskite solar cells with low reflectance on the textured silicon via spin-coating. This breakthrough lays the foundation for the fabrication of optically and electronically optimized perovskite-silicon tandem solar cells.
