Photovoltaic device, process for production thereof, and zinc oxide thin film

摘要

A photovoltaic device is provided which comprises a back reflection layer, a zinc oxide layer and a semiconductor layer stacked in this order on a substrate, wherein the zinc oxide layer contains a carbohydrate. The content of the carbohydrate is preferably in the range of from 1 mu g/cm<3> to 100 mg/cm<3>. Thereby, the zinc oxide layer can be formed without abnormal growth to have a rough surface to achieve sufficient optical confinement effect, and the photovoltaic device is improved in the durability and the photoelectric conversion efficiency.
