Abstract: The present invention provides a light source integrated photovoltaic module. The light source integrated photovoltaic module comprises: a light-transmitting photovoltaic cell having a front surface and a back surface; and a light source provided on the back surface side of the photovoltaic cell. The photovoltaic cell generates electric power by utilizing incident light from the front surface side, the light emits light by utilizing the electric power generated by the photovoltaic cell. The light emitted from the light source is transmitted through the photovoltaic cell and outputted to the front surface side of the photovoltaic cell.

Abstract: A thin-film solar cell module of a light transmission type includes a light-transmissive substrate; a front electrode layer; a rear electrode layer, and a photovoltaic conversion layer. The rear electrode layer, front electrode layer, and photovoltaic conversion layer are sequentially laminated on the light-transmissive substrate. A heat retention member covers the rear electrode layer, and a sealing layer is provided for sealing the rear electrode layer. In certain embodiments, the heat retention member has a light absorptance of 40% or more within a near-infrared wavelength range of 1,500 to 2,000 nm.

Abstract: In a solar battery module of the present invention, a transparent material is provided on the side opposite the light incident side of a solar cell portion formed on a transparent substrate. The solar battery module further includes a printed matter having a prescribed pattern between the solar cell portion and the transparent material. Thus, by integrating a printed matter having for example an illustration, picture, or character in the solar module, the printed matter can be visually recognized from the back or front side, whereby an appearance of the module can be improved.
