Abstract
Material and antireflection structure and methods of manufacturing are provided that produce efficient photovoltaic power conversion from thin film solar cells on flexible substrates. Step-graded antireflection structures are placed on the front of the device structure. Materials of different energy gap are combined in the depletion region of at least one of the semiconductor junctions within the thin film device structure. Conductive, low refractive index layers are deposited on the bottom of the thin film device structure to form an omni-directional back reflector contact.
