Optimizing Nanotextured Solar Cells for Realistic Weather Conditions

Currently, perovskite-silicon (pero-Si) tandem solar cells are the most investigated concept to overcome the theoretical limit for the power conversion efficiency of single-junction silicon solar cells.
Optical simulations are extremely valuable to study the distribution of light within the solar cells, and allow to minimize losses from reflection and parasitic absorption. For monolithic perovskite-silicon solar cells, it is vital that the available light is equally distributed between the two subcells, which is known as current matching. Nanotextures have proven to strongly reduce reflective losses. In this project we will investigate how realistic weather conditions affect the performance of pero-Si modules. We study, how different light management approaches influence the sensitivity of the solar module to the illumination condition.

This project is conducted within the Helmholtz Einstein International Research School in Data Science (HEIBRiDS Graduate School), with the partners Helmholtz-Zentrum Berlin and Zuse Institute Berlin.
