Abstract

We investigated how the nanohole structure on a {111} pyramid textured surface affected the photovoltaic performance of silicon solar cells by varying nanohole depth. During the effective minority carrier recombination lifetime, the surface reflectance decreased with increasing nanohole depth, showing a trade-off relationship. The power conversion efficiency (PCE) of silicon solar cells with the {111} pyramid textured surface peaked at a specific nanohole depth, i.e., 0.43% PCE enhancement (3.32% enhancement relative to a reference cell) was obtained at the nanohole depth of 94.8nm.
