Abstract
A photovoltaic element capable of improving weather resistance is obtained. This photovoltaic element includes a photoelectric conversion layer, a first transparent conductive film formed on a surface of the 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 the photoelectric conversion layer opposite to the incidence side and including a second indium oxide layer having (222) orientation and one X-ray diffraction peak.

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.
A photovoltaic module comprising:
- a photoelectric conversion layer;
- a plurality of photovoltaic elements, each of which including 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;
- a transparent surface protector arranged on a surface of said first transparent conductive film closer to said incidence side;
- and
- a resin film arranged on a surface of said second transparent conductive film opposite to the incidence side,
- 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.
