Abstract: A method for manufacturing a multi-junction photoelectric conversion device includes forming a first electrode on a first photoelectric conversion unit including a first semiconductor layer as a photoelectric conversion layer, the first electrode including a plurality of patterned regions separated from one another by separation grooves; and eliminating a leakage existing in the first semiconductor layer by applying a reverse bias voltage between one of the patterned regions of the first electrode and a second photoelectric conversion unit comprising a second semiconductor layer as a photoelectric conversion layer. The application of the reverse bias voltage is performed while irradiating the second photoelectric conversion unit with light, generating a photocurrent in the second photoelectric conversion unit that is larger than a photocurrent in the first photoelectric conversion unit.

Abstract: Disclosed is a solar cell having a collecting electrode on one main surface of a photoelectric conversion section. The collecting electrode includes a first electroconductive layer and a second electroconductive layer in this order from the photoelectric conversion section side, and further includes an insulating layer between the first electroconductive layer and the second electroconductive layer. The first electroconductive layer includes a low-melting-point material, and a part of the second electroconductive layer is conductively connected with the first electroconductive layer through, for example, an opening in the insulating layer. The second electrode layer is preferably formed by a plating method. In addition, it is preferable that before forming the second electroconductive layer, annealing by heating is carried out to generate the opening section in the insulating layer.

Abstract: In the solar cell module, a first solar cell and a second solar cell are stacked together with an electroconductive member interposed therebetween, such that a cleaved surface-side periphery on a light-receiving surface of the first solar cell overlaps a periphery on a back surface of the second solar cell. The first solar cell and the second solar cell each have: photoelectric conversion section including a crystalline silicon substrate; collecting electrode; and back electrode. At a section where the first solar cell and the second solar cell are stacked, the collecting electrode of the first solar cell and the back electrode of the second solar cell are electrically connected to each other by coming into contact with the electroconductive member. An insulating member is provided on a part of the cleaved surface-side periphery on the light-receiving surface of the first solar cell, where the collecting electrode is not provided.
