Transparent layered product and glass article using the same

A photoelectric conversion device, comprising:

• a transparent layered product, including
• a glass sheet,
• an undercoating film comprising at least two layers formed on the glass sheet,
• wherein the undercoating film has a surface roughness,
• a conductive crystalline coating film, which is formed on the undercoating film, the coating film having a surface roughness;
• at least one photoelectric conversion unit;
• and
• a back electrode,
• wherein the crystalline coating film includes, at its surface, a transition layer in which a refractive index varies continuously in its thickness direction, and
• the at least one photoelectric conversion unit and the back electrode are stacked on the crystalline coating film in this order,
• wherein the transition layer has a thickness in a range between 13% and 65% of a thickness of a layer having a substantially constant refractive index in the crystalline coating film.

A method of manufacturing a transparent layered product comprising:

• forming an undercoating film comprising of at least two layers by a CVD method on a glass ribbon in a glass sheet production line, and
• forming a coating film by a CVD method on the undercoating film in the production line,
• wherein the temperature of the glass ribbon during the forming of the undercoating film and the coating film ranges from approximately 615° C. to 715° C.,
• the undercoating is formed so as to have a rough surface, and
• the coating film is formed so as to have a transition layer at its surface in which a refractive index of the transition layer varies continuously in its thickness direction, wherein a thickness of the transition layer ranges from 13% to 65% of a thickness of a layer having a substantially constant refractive index in the coating film.
