THIN FILM SOLAR CELL

摘要

A thin film solar cell includes a substrate; a light transmissive electrode which is disposed on the substrate and transmits light that is incident on the substrate; at least one photoelectric conversion unit which is disposed on the light transmissive electrode; and a reflective electrode which is disposed on the photoelectric conversion unit and which reflects the light transmitted through the photoelectric conversion unit to the photoelectric conversion unit, wherein the light transmissive electrode includes a first electrode layer having a first band gap and a second electrode layer having a second band gap which is greater than the first band gap. In addition, the first electrode layer is to form a light emitting surface in the textured surface towards the photoelectric conversion unit.
