- Patent Document 1 Japanese Patent Laid-Open No. 60-148174 discloses a solar cell provided with a selective reflection layer that selectively reflects part of the visible light spectrum.
- a selective reflection film that reflects a part of the visible spectrum of sunlight is coated as in Patent Document 1, an observer can see the color of the reflected spectrum of visible light.
- a battery can be obtained.
- Patent Document 2 Japanese Utility Model Publication No. 7-29646
- a solar cell provided with a wavelength selective scattering layer that allows a part of the scattered light to reach an observer and transmits light other than a specific wavelength is disclosed.
- Patent Document 1 JP-A-60-148174
- Patent Document 2 Actual Fairness 7-29646
- Patent Documents 1 and 2 when a selective reflection layer or a wavelength selective scattering layer is provided in order to reflect or scatter part of the visible light spectrum, A part of the battery is not used for solar power generation. For this reason, the techniques disclosed in Patent Documents 1 and 2 have a problem in that the power generation efficiency decreases in principle.
- Another object of the present invention is to provide a visible light transparent plate that does not reduce the power generation efficiency of the solar cell.
- a solar cell panel according to the present invention includes a transparent plate characterized by absorbing infrared light and emitting visible light, and a solar cell covered with the transparent plate.
- the transparent plate characterized by absorbing infrared light and emitting visible light contains two or more lanthanoid series atoms (or ions thereof). Materials are used, especially glass. An atom that absorbs infrared light efficiently can be selected as one of at least two types of atoms, and an atom that generates visible light can be selected as the other atom. Note that the lanthanoid atoms doped in the material behave as ions when performing a coloring operation, and thus can be a material containing these ions.
- a transparent plate used in the solar cell panel a solar cell transparent plate characterized by absorbing infrared light and emitting visible light can be obtained.
- the present invention does not contribute to the power generation operation of the solar cell! Since the color is developed based on the solar energy of the infrared component, the power generation efficiency of the solar cell is not reduced.
- FIG. 1 (a) and (b) are explanatory views showing an overview and operating principle of a solar cell panel according to a first embodiment of the present invention, respectively.
- FIG. 2] (a) and (b) are respectively an overview of the solar cell panel according to the second embodiment of the present invention. It is explanatory drawing which shows an operation principle.
- FIG. 3 is a graph showing the sunlight spectrum.
- FIG. 5 is a graph showing the absorption characteristics of a silicon solar cell.
- a solar cell panel made of amorphous silicon or single crystal silicon power absorbs sunlight and generates electricity by energy irradiated by sunlight.
- the solar spectrum shown in Fig. 3 includes a broad spectrum from the visible range to the infrared longer than lOOOnm.
- infrared light above lOOOnm is mostly used for solar cell power generation. Cunning is powerful.
- the color is generated based on the solar energy of the infrared component that does not contribute to the power generation operation of the solar cell, the power generation efficiency of the solar cell is not reduced! Further, according to the present invention, various light-emitting panels can be realized, so that it has an excellent effect from a decorative viewpoint as compared with the conventional black panel.
- FIGS. 1 (a) and 1 (b) are an explanatory diagram showing an overview of the solar cell panel 10 according to the first embodiment of the present invention and its operating principle.
- the illustrated solar cell panel 10 includes a solar cell 12 using amorphous silicon, and a transparent plate 11 having a thickness of about 5 mm attached on the solar cell 12.
- the transparent plate 11 also has Pyrex (registered trademark) glass power, and is doped with two kinds of lanthanoid series atoms (but including ions that are ionized), ytterbium (Yb) and elpium (Er). /!
- Erbium (Er) that absorbs infrared light energy by ytterbium (Yb) and further transfers energy emits visible light. Since the color is generated based on the solar energy of the infrared component without contributing to the power generation of the solar cell, it is possible to obtain an excellent solar cell panel from a decorative point of view without reducing the power generation efficiency of the solar cell.
- FIG. 2 (a) is a perspective view showing an overview of the solar cell panel 20
- FIG. 2 (b) is a diagram for explaining the operation principle.
- the illustrated solar cell panel 20 includes a solar cell 22 using single crystal silicon and a transparent plate 21 attached on the solar cell 22.
- the illustrated transparent plate 21 is made of soda glass and doped with samarium (Sm) and europium (Eu) as two types of lanthanoid series atoms!
- the principle of the solar cell panel according to this embodiment will be described.
- the transparent plate 21 hits the solar light L1
- energy is absorbed by samarium (Sm) that absorbs infrared light contained in the solar light L1. It generates electrons with this, and generates visible light L2 when europium (Eu) recombines with electrons.
- Eu europium
- the solar battery panel 20 appears to be colored.
- cerium (Ce) may be used instead of europium (Eu) in this embodiment.
- the transparent plate develops color based on the solar energy of the infrared component that does not contribute to the operation of the solar cell, so it does not reduce the power generation efficiency of the solar cell.
- An excellent solar cell panel can also be obtained from a decorative point of view. .
- the transparent plate suitable for the solar cell panel of the present invention may use the principle of either Example 1 or Example 2, but the color development differs depending on the type of atoms added to the transparent plate.
- the solar cell panel can be colored with various colors.
- the transparent plate according to the present invention is not limited to glass, and is formed of, for example, a transparent plastic. May be.
- the solar panel according to the present invention is particularly suitable for a wall of a high-rise building because it does not impair the aesthetic appearance even if it is attached to a vertical wall that is more conspicuous than a roof used only for ordinary houses. .
- attaching a transparent plate that emits the same color as the original paint color does not impair the aesthetic appearance.
- various kinds of light emission can be obtained by appropriately selecting and combining elements that generate visible light. Because it is possible to realize a solar cell panel that can be used, it can be used not only as a solar cell as a light-electric conversion element, but also as an outer wall material with a decorative function in buildings, etc. it can.
