ABSTRACT:
A photovoltaic device including a substrate, a first electrode layer provided on the substrate, a photoelectric conversion layer provided on the first electrode, and a second electrode layer provided on the photoelectric conversion layer. A discontinuous interfacial layer is provided at at least one of the interfaces between a first conductivity type layer and a photoactive layer provided in the photoelectric conversion layer, between the photoactive layer and a second, opposite conductivity type layer of the photoelectric conversion layer, and between the photoelectric conversion layer and the second electrode layer. The at least one interface provided with the discontinuous interfacial layer may be so textured that portions of the interface not provided with interfacial layers project toward the substrate.
