<p><P>PROBLEM TO BE SOLVED: To provide a photoelectric conversion device and a production method therefor which can improve the optical absorption characteristics of a power-generating layer by controlling and optimizing the three-dimensional structure of a rear-face electrode layer. <P>SOLUTION: The photoelectric conversion device includes a transparent electrode layer 2, at least two power generating layers 91 and 92, and a rear-surface electrode layer 4 on a substrate 1. In the photoelectric conversion device, the rear-surface electrode layer 4 has a silver film, and the surface of the rear-surface electrode layer 4 on the side of the substrate 1 has a concavo-convex shape. When the sum of the amount of the light reflected on the surface of the rear-surface electrode layer 4 and the amount of the light absorbed by the rear-surface electrode layer 4 is 96% or lower of the sum of the amount of the light reflected on the surface of the rear-surface electrode layer 4 and the amount of the light absorbed by the rear-surface electrode layer 4 when the rear-surface electrode layer 4 is smooth. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
