Abstract:
1. A photovoltaic element comprising: a photoelectric conversion layer; a first transparent conductive film formed on a surface of said photoelectric conversion layer closer to an incidence side and including a first indium oxide layer having (222) orientation and two X-ray diffraction peaks; and a second transparent conductive film formed on a surface of said photoelectric conversion layer opposite to said incidence side and including a second indium oxide layer having (222) orientation and one X-ray diffraction peak, wherein the first and second transparent conductive film layers are configured such that a temperature rise due to light incidence upon the first transparent conductive film is greater than that of the second transparent conductive film and a coefficient of thermal expansion of the second transparent conductive film is greater as compared with that of the first transparent conductive film.
