Title: Light trapping in thin film solar cells using textured photonic crystal

Abstract

A solar cell includes a photoactive region that receives light. A photonic crystal is coupled to the photoactive region, wherein the photonic crystal comprises a distributed Bragg reflector (DBR) for trapping the light.
