Three‐Dimensional Photonic Crystal Intermediate Reflectors for Enhanced Light‐Trapping in Tandem Solar Cells

A three-dimensional photonic crystal intermediate reflector for enhanced light trapping in tandem solar cells is presented. The intermediate reflector consists of a transparent and conductive ZnO:Al inverted opal sandwiched in between the top amorphous silicon and bottom microcrystalline silicon cell.
