    摘要： 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.

    摘要： The solar cell includes a plurality of light-receiving-side finger electrodes on a light-receiving surface of a photoelectric conversion section having a semiconductor junction. The light-receiving surface of the photoelectric conversion section is covered with a first insulating layer. Each light-receiving-side finger electrodes include: a first metal seed layer provided between the photoelectric conversion section and the first insulating layer; and a first plating metal layer being conduction with the first metal seed layer through openings formed in the first insulating layer. The solar cell includes an isolated plating metal layer pieces contacting neither the light-receiving-side finger electrodes nor the back-side finger electrodes. On the surface of the first insulating layer, an isolated plating metal crowded region is present in a form of a band-shape extending parallel to an extending direction of the light-receiving-side finger electrodes.

    摘要： A solar cell module includes a solar cell string in which a first solar cell and a second solar cell are arranged apart from each other along a first direction. The first and second solar cells are connected by a strip-shaped wiring member, and the solar cell string is arranged between a light-receiving-surface protection member and a back-surface protection member. The wiring member has, along the first direction, an uneven region where the first principal surface is provided with unevenness, and a flat region where the first principal surface is not provided with unevenness or is provided with unevenness that is smaller in height than the uneven region. The uneven region extends from the light-receiving surface of the second solar cell to the back surface of the first solar cell.

    摘要： The solar cell includes a collecting electrode on a first principal surface of a photoelectric conversion section. The collecting electrode comprises a first electroconductive layer and a second electroconductive layer in this order from the photoelectric conversion section side. An insulating layer is provided on the first principal surface of the photoelectric conversion section so as to cover substantially the entire surface of the region where the first electroconductive layer is not provided and a part of the first electroconductive layer. The insulating layer on the first electroconductive layer has an opening, and the second electroconductive layer is a plating layer that is in conduction with the first electroconductive layer through the opening section of the insulating layer. The first electroconductive layer contains a metal particle component and an insulating material. The metal particle component of the first electroconductive layer includes primary particles and secondary particles. It is preferable that in a cross-section of the first electroconductive layer, the area ratio of the secondary particles to the total of the primary particles and the secondary particles and the coefficient of variation of the particle size are respectively within specific ranges.

    摘要： A solar cell module, which is easily coordinated with the color of an exterior member at the installation position, comprises a solar cell; a light receiving side sealing material and a light receiving side protection member laminated and disposed in this order on a light receiving side with reference to the solar cell; and a back-side sealing material and a back-side protection member laminated and arranged in this order on a back side on the opposite side from the light receiving side. A value computed from a measured value of the color of reflected light combining positive reflected light and diffused reflected light which are based on light that has become incident on an object to be measured, and a measured value of the color only of the diffused reflected light based on the light that has become incident on the object to be measured, satisfies a specific condition.

    摘要： 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.
