Abstract
A photovoltaic cell comprising a substrate, a back reflector, a transparent conductive layer, and a photoelectric conversion layer, wherein the transparent conductive layer has holes on the surface, is provided. Additionally, a photovoltaic cell comprising a substrate, a back reflector, a transparent conductive layer, and a photoelectric conversion layer, wherein diffuse reflectance of the back reflector is 3 to 50%, is provided. According to the above-described structures, processability, yield and reliability of the photovoltaic cell can be improved, while photoelectric conversion efficiency is maintained at a high level due to back-surface diffuse reflection.
