摘要： Disclosed are a multi-junction photoelectric converter and an integrated multi-junction photoelectric converter, having a two-terminal structure, of which layers are laminated under less constraint of the previously laminated layers. Also disclosed is a method for manufacturing such converters. A plurality of photoelectric conversion cells of which spectral sensitivities differ from each other are laminated. At least the photoelectric conversion cells (2, 4) located at a light receiving end and the other end have conductive thin film layers (5a and 5b, 5c and 5d), respectively, on the top layers to be connected thereof. Another photoelectric conversion cell (3) has conductive thin film layers (16a, 16b) at the top and bottom layers, respectively, to be connected thereof. The top and bottom layers are joined to the top and bottom layers of the other cells via anisotropic conductive adhesive layers (6a, 6b) containing conductive fine particles in a transparent insulating material. The conductive fine particles in the anisotropic conductive adhesive layers (6a, 6b) electrically connect the layers in a direction along which the layers are laminated, and the conductive thin film layers (5a, 5b, 5c, 5d) electrically connect the photoelectric conversion layers (2, 3, 4) serving as materials to be joined in lateral directions (in-plane direction).
