Description of the Invention: [Technical Field of the Invention] The present invention relates to a solar cell panel structure, which refers to a double-sided solar cell transparent plate structure. [Prior Art] With the increase in energy demand and the emergence of global warming issues, it is an alternative energy source that combines sustainability and environmental protection - including wind, water, biomass, geothermal water, seawater and sand, and solar energy. In recent years, it has received much attention and has actively engaged in energy conversion technologies and systems. The solar cell can directly convert the solar ray into electric energy, and it is the most popular. If classified according to the type of material, the solar cell can be classified into a single crystal stone, a polycrystalline stone, an amorphous stone, and an organic too hetero battery. The single crystal 7 is too heterogeneous to have a conversion efficiency of up to 25% and a south stability. However, a higher price has become an obstacle to popularization, and a low-cost organic solar cell/dye-sensitized solar cell has received a little attention. The structure of the battery 10 is a structure of the first embodiment, which includes an upper substrate 12, an electrolyte layer 14, and a lower substrate 16. The upper substrate 12 is also referred to as a working electrode, on which a transparent conductive film 18 is formed, and the surface of the transparent guide 18 is coated with a semiconductor light-sensitized layer 2G. The wire __ is generally from the upper substrate 12 into the human 'when the light source is larger, the greater the power transfer amount, so the conventional technology will be on the upper substrate 12 above the anti-reflection layer 22 In order to increase the amount of light incident, the loss of the (4) lining rate of the upper substrate 12 is reduced. However, the human light surface of the structure is emitted from a single-sided person, so that the area of the receiving light source is greatly limited, resulting in insufficient ability to absorb sunlight, and space. Take advantage of the limitations. Furthermore, 'Building Integrated Sunlight System (BIpv) is a green building that is currently highly recommended, 3 201039454. However, the existing solar power system uses a higher unit price of single crystal solar cells, so how can it be lower cost? The combination of organic dye-sensitized solar cells in this system has also become an important issue in order to effectively increase the popularity of green buildings and increase the use of alternative energy sources for sustainability and environmental protection. In view of the above-described drawbacks of the present invention, a double-sided solar cell transparent plate structure has been proposed to effectively overcome the above problems. SUMMARY OF THE INVENTION The main object of the present invention is to provide a double-sided solar cell transparent plate structure capable of receiving double-sided incident light and effectively improving the photoelectric conversion efficiency to more than twice the performance under the same unit area. At the same time, it strengthens the overall thickness of the dye-sensitized solar cell when it is applied to energy-saving smart windows, and increases the mechanical strength and resistance to moisture and ultraviolet rays, thereby achieving the effect of energy saving and power generation. It is still another object of the present invention to provide a double-sided solar cell transparent panel structure which can reduce the cost of building an integrated sunlight electrical system (BIPv). In order to achieve the above object, the present invention provides a double-sided solar cell transparent plate structure comprising: a double-sided conductive substrate; and a transparent conductive t substrate, wherein the double-sided conductive substrate is scaled in the middle; and - the first, the The second photoelectric conversion unit is disposed between the transparent conductive substrate and the double-sided conductive substrate between the towels.
