Abstract :
we present the design, processing and characterization of Si-on-insulator thin film solar cells integrated with textured photonic backside reflector. A processing method was successfully developed to integrate the photonic structure to SOI solar cells. Cells at all thicknesses demonstrated significant external quantum efficiency (EQE) enhancement due to the back reflector.
