Toward Perfect Light Trapping in Thin‐Film Photovoltaic Cells: Full Utilization of the Dual Characteristics of Light

A novel light trapping configuration called a compound parabolic trapper (CPT) is proposed. A CPT integrated with a V-groove textured surface increases the power conversion efficiency of polymer solar cells from 9.38% to 10.4%. A multiscale system applying the integrated schemes to a nanopatterned plasmonic PV improves it further to 10.8%, achieving almost black absorption of 94.1%.
