Document Type and Number:
WIPO Patent Application WO/2012/014924
Kind Code:
A1
Abstract:
[Problem] To provide a photoelectric conversion device having high adhesion between a light-absorbing layer and an electrode layer, and having high photoelectric conversion efficiency. [Solution] A photoelectric conversion device (10) comprising a light-absorbing layer (3) containing a chalcopyrite compound semiconductor and oxygen. Voids (3a) are present in the interior of the light-absorbing layer (3). The atomic concentration of oxygen near the voids (3a) is greater than the average atomic concentration of oxygen in the light-absorbing layer (3).
