Abstract
Optical simulations of perovskite/silicon tandem solar cells show that nanotexturing both sides of the perovskite top cell yields the strongest antireflective effect. Cells with an intermediate texture in-between the perovskite and silicon sub cells perform comparably to configurations with a fully planar top cell. However, in experiment intermediate-textured solar cells perform slightly better than their planar counterparts. A numerical sensitivity analysis shows that this can be attributed to the thickness of a silicon oxide layer in-between the two sub cells: this thickness affects the optics for a fully planar top cell, but does not affect the performance for intermediate texturing.
