Description

  The present invention relates to a solar panel with a decorative pattern, and in particular, sandwiches a plurality of solar cells arranged side by side with an edge or a frame around the front panel and the back panel, A solar cell with a decorative pattern, which is composed of a surface side edge portion that opposes an edge portion or a frame portion around the solar battery cell and a surface side panel portion that opposes the solar battery cell and causes sunlight to enter the solar battery cell Regarding panels.

  A photovoltaic cell refers to a power device that uses the photovoltaic effect to convert received light energy into electricity immediately. The light energy incident on the inside of the solar battery cell is directly absorbed by electrons, guided to an electric field provided in advance, and output as electric power to the outside of the solar battery cell. A panel-shaped product unit in which a plurality of solar cells are connected in series and parallel to obtain necessary voltages and currents is called a solar cell panel.

  Silicon is mainly used as the material of the solar battery cell. This silicon is roughly classified into crystalline silicon and amorphous silicon. Among these, the solar battery cell using amorphous silicon is classified into a thin film silicon type having a thickness of 10 μm or less. This is because the light absorption coefficient is high, so that practical use is possible even if the thickness is small. And it has the characteristic that an output does not fall easily at high temperature compared with the photovoltaic cell using crystalline silicon. Furthermore, it has a characteristic of high efficiency under extremely low illuminance. On the other hand, solar cells using crystalline silicon have conventionally required a silicon layer of at least about 200 μm to obtain a practical amount of absorption because of their low light absorption coefficient. Solar cells that can be classified into thin film silicon types of several μm to 50 μm have been developed.

  A film type solar cell panel in which the thickness of the crystalline silicon or amorphous silicon silicon layer is reduced has been put into practical use. It is called a film-type solar cell panel because flexibility like a film is obtained by making it a thin film. In addition, a hybrid solar cell panel in which crystalline silicon or amorphous silicon is laminated to improve conversion efficiency and improve temperature efficiency as compared with ordinary crystalline silicon has been developed.

  FIG. 7 shows a general film type solar cell panel 40. FIG. 7A shows a plan view of the film type solar cell panel 40, and FIG. 7B shows a CC cross section of FIG. 7A. The film-type solar battery panel 40 includes a plurality of solar battery cells 2 arranged side by side with an edge 3 around the periphery, using an adhesive (or sealing material) 22 with a front surface side panel 4a and a back surface side panel 4b. It is a sandwiched panel. The front side panel 4a is made of, for example, ETFE (thermoplastic fluororesin), and the back side panel 4b is made of ETFE (thermoplastic fluororesin), a steel plate, or PET (polyethylene terephthalate). Moreover, the terminal box 21 which takes out electricity is attached to an edge part.

  Since this film type solar cell panel 40 is light and flexible, it is used in places where it is difficult to apply it to a conventional flat plate solar cell panel made of crystalline silicon, such as a curved roof. Patent Document 1 discloses a roll curtain device in which a film-type solar cell panel is pasted on a window surface of a roll screen body.

  Several technologies have been devised for solar cell power generation systems using solar cell panels. For example, Patent Document 2 discloses a light energy collecting device that can suppress a temperature rise of a photoelectric conversion element and can effectively use thermal energy contained in incident light. Here, sunlight is reflected and collected by the concave mirror, and the cold mirror enters the collected light, reflects visible light contained in this light, and transmits infrared light. And it is described that a solar cell receives visible light and generate | occur | produces a photovoltaic power.

The phosphorescent agent is a material that absorbs ultraviolet rays from a light source and gradually emits phosphorescence in a dark place. This light storage refers to the property that a substance continues to emit light for a certain period of time after excitation light such as ultraviolet rays and visible light disappears from the substance. As the phosphorescent agent, for example, inorganic pigments such as alumina oxide are known. The object containing the phosphorescent agent has phosphorescence luminance (cd / m ² ) due to the phosphorescence.
