NOVELTY - Photoelectric conversion device (I), comprises: a first cell (102) having a photoelectric conversion function; a structure body (103) over the first cell, where the structure body includes a fibrous body and a resin; and a second cell (105) having a photoelectric conversion function over the structure body, where the first cell and the second cell adhere to each other with the structure body.    USE - (I) is useful as the solar cell, solar cell module, solar cell string, and solar cell array.    ADVANTAGE - (I): has increased mechanical strength; can convert sunlight including light in a wide range of wavelengths from ultraviolet rays to infrared rays into electrical energy with higher conversion efficiency without waste and can be manufactured in a simpler process, as it utilizes many cells which absorb light with various wavelengths; and has increased portability along with a reduction in weight of the substrate, since semiconductor layers with different spectral sensitivity characteristics can be formed over a plastic substrate.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) a photoelectric conversion device, comprising: a first substrate (101); a first cell (102) having a photoelectric conversion function over the first substrate; a structure body (103) over the first cell, where the structure body includes a fibrous body and a resin; a second cell (105) having a photoelectric conversion function over the structure body; and a second substrate (104) over the second cell, where the first cell and the second cell adhere to each other with the structure body; and    (2) a method for manufacturing a photoelectric conversion device, comprising: forming a first cell having a photoelectric conversion function; forming a second cell having a photoelectric conversion function; making the first cell adhere to a structure body including a fibrous body and a resin; and making the second cell adhere to the structure body.
