Abstract: A photovoltaic or light detecting device is provided that includes a periodic array of dome or dome-like protrusions at the light impingement surface and a metal-less reflector/back electrode at the device back. The beneficial interaction between an appropriately designed top protrusion array and metal-less reflector/electrode back contact (R/EBC) serves (1) to refract the incoming light thereby providing photons with an advantageous larger momentum component parallel to the plane of the back (R/EBC) contact and (2) to provide optical impedance matching for the short wavelength incoming light. The metal-less reflector/back electrode operates as a back light reflector and counter electrode to the periodic array of dome or dome-like structures. A substrate supports the metal-less reflector/back electrode.
