Abstract: A photoelectric transducer comprising in order: a substrate (1, 5), a rear side electrode (2, A), a photoelectric active (photovoltaic) layer (3), and a front side electrode (4, B). The substrate (1, 5) is constituted by a flexible, elastic web or foil, that on a front side of the substrate has a three-dimensional surface pattern of raised and depressed surface portions formed therein. The photoelectric active (photovoltaic) layer (3) is deposited onto the three-dimensional surface pattern. The front side electrode (4, B) and rear side electrode (2, A) are electrically conductive layers, which comprise electrically conductive materials, or which are electrically conductive coatings. The elasticity and flexibility are important features making possible to durably mount the solar cell of the invention on complex surfaces comprising inwardly bending (concave) as well as outwardly bending (convex) surface parts.
