Perovskite/silicon tandem solar cells (PSTSC) are amongst the most promising routes to increase the power conversion efficiency (PCE) of silicon-based solar cells. Just recently, a new world record of 29.5% PCE was communicated, which is the first time that a PSTSC surpasses the theoretical limit for silicon single junction solar cells of 29.4%. Many of the highly efficiency PSTSC use planar perovskite top cell layer stacks because of the compatibility with solution processing, which is the preferred fabrication process for perovskite solar cells. However, light management can further improve the optical performance of PSTSC. For example, smooth nanotextures can help to reduce reflective losses and increase the absorption of light in the absorber layers without compromising the compatibility with perovskite solution processing.
