Rougher Interfaces May Increase Efficiency of Next-generation Solar Cells

In simulations and experiments, researchers demonstrate that introducing tiny nanoscale texturing on the surfaces of materials in perovskite/silicon tandem solar cells can significantly increase efficiency by reducing the amount of light energy that is lost due to reflection. A new nanotextured design can achieve a power conversion efficiency potential above 29%, which simulations suggest could...
