Description

  The present invention relates to a roll screen that becomes a double screen when in use. More specifically, the present invention relates to a roll screen with a solar cell in which a screen and a solar cell film sheet have a double structure when in use.

  Conventionally, roll screens are installed in windows and spaces because of their light shielding and storage properties, and are used to block light rays, heat rays, or lines of sight indoors and outdoors. On the other hand, solar cells were installed on outdoor roofs and outer walls to increase power generation efficiency. However, as global warming and eco-consciousness increased, a see-through type installed on window glass was developed. In addition, it has been proposed that a thin sheet-like flexible sheet is used as a mobile power source in the form of a roll having good storage properties and used indoors and outdoors. Furthermore, proposals have been made to provide a power generation function for a roll screen used indoors. However, since this type of roll screen is first required to have a light-shielding function, a sufficient light-shielding function cannot be obtained simply by providing a solar cell on a flexible film sheet. Further, in order to enrich the living space, the roll screen is required to have a design. Based on the idea of making it possible to sufficiently exhibit the power generation function and the light-shielding function, a roll comprising a solar cell film sheet integrally formed so as to sandwich a plurality of solar cell unit cells by lamination processing is used as a screen part. A screen has been proposed (see, for example, Patent Document 1). The power generation function of the roll screen having such a configuration is performed by a solar cell film sheet, and the light shielding function is a natural fiber as a light shielding member on the back surface side of the laminated solar cell unit cell sandwiching a plurality of solar cell unit cells. , Chemical fibers, etc., are bonded to the solar cell unit cell-free part or the entire back surface, a light-shielding member is sealed in the laminate, a light-shielding material is mixed in the laminated film itself, metal deposition, coating I was doing. Moreover, when designability is calculated | required, the design layer was provided with the printing film and the coloring agent in the further outer side of the light-shielding member.

JP 2011-179193 (paragraphs [0024] to [0048], paragraphs [0090] to [0099], FIGS. 1 to 6)

  However, the roll screen disclosed in Patent Document 1 has the following problems with respect to light shielding performance, design properties, power generation performance, and flexibility. When a light-shielding agent is applied to a solar cell film sheet and deposited, the coating agent or vapor deposits color on the power generation surface of the solar cell film sheet of the rolled-up roll screen, or the coating agent is peeled off to remove the sun. There is a possibility that the power generation performance of the battery, the light shielding function, and the design may deteriorate. When a coating layer or the like is further provided in order to maintain these functions, the flexibility as a solar cell film sheet cannot be sufficiently exhibited due to the increase in thickness, which is not practical as a roll screen. Moreover, when a light shielding member is attached to the back side of the solar cell film sheet, the flexibility of the roll screen is deteriorated due to an increase in the degree of attachment or the thickness of the light shielding member, and the attached light shielding member may be peeled off. There is. In addition, there is a concern that the design properties may be deteriorated due to bubbles or the like when the light shielding member is attached, and depending on the material of the light shielding member, there is a problem that the power generation performance of the solar cell is deteriorated due to heat storage. Furthermore, when a light-shielding material is added to the laminate material that coats the solar cell unit cells, the electrically conductive material, the material with the heat storage property and the heat storage color, etc. There is a concern that the material used may be restricted so as not to decrease the width, and the range of designability required for the roll screen is reduced. In addition to such problems that the light shielding performance, power generation performance, and designability deteriorate, if you want to increase or decrease the light shielding performance by changing the interior of the room or changing the surrounding environment, it is necessary to replace the entire roll screen, It was not economical.

  An object of the present invention is to economically provide a roll screen with a solar cell that is not only excellent in light shielding performance and designability but also excellent in power generation performance and flexibility.
