いる。(B) Conventional technology As a so-called solar cell provided with a photoelectric conversion element, as an application example to photovoltaic power generation, such a solar cell is formed into a panel and installed on the roof of a house, or a film-shaped photoelectric conversion element It has also been attempted to provide the photoelectric conversion element on a translucent roof tile as described in JP-A-60-31359 to form a solar cell roof tile and lay it directly on the roof.

を可能ならしめ、窓としての機能を保っている。In addition, recently, for the purpose of reducing the work and parts required to install the solar cell and building materials integrally like a solar cell roof tile, a film-like photoelectric conversion device in which a large number of through holes are discretely formed in a transparent window member is provided. A solar cell window provided with an element was prototyped and announced by the applicant of the present application. That is, in such a solar cell window, after forming a film-like photoelectric conversion element on the entire surface of a translucent window member, natural light can be taken into the room by punching a large number of through holes by an etching process. It retains its function.

めに光電変換出力が全く得られないこともある。When such a solar cell window is configured to be movable in a direction in which at least one intersects with the other, that is, to be openable / closable, when one window member moves and intersects with the other window member, it is exposed to the outside. The photoelectric conversion element of one window member shields the other indoor photoelectric conversion element, and the photoelectric conversion output of the other shielded window member decreases, and one window member completely covers the other window member. When it is covered with, the photoelectric conversion output is hardly obtained from the window member. That is, the photoelectric conversion output of the other window member increases and decreases depending on the open / closed state of one window member, and even under the same solar radiation condition, one photoelectric conversion output of one window member or a fixed type photoelectric conversion output is fixed. I can't get it. Therefore, for example, when the photoelectric conversion outputs of a plurality of window members are connected in series, if there is even one with a low photoelectric conversion output, only a low serial output can be obtained as a whole, and in the worst case, the shielded window member Since the photoelectric conversion element acts as a diode in the direction opposite to the connection direction, photoelectric conversion output may not be obtained at all.
