New records in perovskite-silicon tandem solar cells through improved light management

Using microstructured layers, a team has been able to increase the efficiency of perovskite-silicon tandem solar cells, achieving 25.5 %, which is the highest published value to date. At the same time, computational simulations were utilized to investigate light conversion in various device designs with different nanostructured surfaces. This enabled optimization of light management and detailed energy yield analyses.
