New Description: [New Technology Field] This paper is about a solar light reflection and refraction double light collecting device, especially a light collecting device that enables solar energy chips to receive solar energy energy efficiently and convert it into electric energy. [Prior Art] In recent years, the price of oil has risen several times since the second oil crisis was lifted, which has led to an increase in the cost of shipping and shipping. The cost of plastics in life has also increased, making the global economic slowdown. Trends, in addition, aircraft, automobiles, locomotives, ships and other vehicles that generate electricity through the burning of oil, will emit carbon dioxide, the earth's carbon dioxide content continues to increase 'causing the greenhouse effect is increasingly serious and the global climate is different from the crane' Energy reserves are limited', so countries have recently been actively developing alternative energy sources such as biomass, wind power or solar power. In the case of solar power generation, the use of natural energy—sunlight, and the light-guide effect induced by sunlight combined with semiconductors, further converts light energy into electrical energy, where 'sunlight illuminates into the semiconductor of solar cells, causing energy levels. Migrate and stimulate the electrons and holes of the semiconductor to generate a free carrier migration movement between the valence band and the conductive electron band, thereby increasing the conductivity to achieve the purpose of converting light energy into electrical energy, and to improve the photoelectric conversion of the solar cell. For efficiency, it is necessary to increase the number of electrons and holes that are migrated. Therefore, it is necessary to increase the amount of sunlight that is radiated into the solar cell and reduce the loss of sunlight reflection. 4 M356016 - However, in order to reduce the reflection of sunlight, the solar cell reduces the energy that can excite electrons and holes, and most of them seek improvement in the process, and etch a pyramid type on the surface of the anti-reflection film on the wafer of the solar cell. The pyramidal surface reduces the reflection of light, but the process technology is more difficult, so the cost is relatively higher, and it cannot meet the economic benefits, so the promotion and application of solar cells are subject to considerable restrictions. In addition, when the solar cell wants to achieve a certain amount of electricity output, it is necessary to calculate the area of the solar wafer of the required solar cell, and the intensity of the sunshine in the unit surface, because the intensity of the sunshine per unit area varies according to the region. Therefore, in order to generally improve the efficiency of solar cells, it is necessary to set a large area of solar wafers to absorb sunlight, but in contrast, the installation cost of the solar cells is increased, which affects the user's willingness to set up. [New content] The main purpose of this creation is to provide a solar light reflecting and refracting double light collecting device, which is designed to increase the solar energy received by the solar wafer per unit area, thereby improving the photoelectric conversion efficiency. In order to achieve the goal, the solar reflection and refraction double concentrating device designed by the present invention includes at least one optical module, and the concentrating module includes: a base; a solar wafer Placed on the base; and a total reflection light concentrating member disposed above the base, and the solar ray wafer is located between the base and the total reflection concentrating member, the total reflection concentrating member is on one side A light collecting surface having a plurality of curved surface portions is disposed on the other side, and the other side surface 5 M356016 is provided with a light transmitting portion having a curved surface having a varying curvature, and the light transmitting portion corresponds to a position where the solar wafer is disposed. According to the above description, when the parallel sunlight is irradiated to the light collecting module, the total reflection light collecting member above the solar wafer is first passed, wherein the sunlight passing through the transparent portion of the total reflection collecting member It will be refracted onto the solar wafer, and the sunlight passing through the outer periphery of the light transmitting portion will be non-perpendicularly irradiated onto the light collecting surface having the plurality of curved surface portions, and total reflection of sunlight will be performed in the total reflection light collecting member. Further reflecting and illuminating the solar light irradiated onto the light collecting surface having the plurality of curved surface portions onto the solar wafer, the total reflection light collecting member can effectively concentrate sunlight onto the solar wafer, so that the solar energy The solar light energy received by the wafer per unit area is increased, thereby increasing the photoelectric conversion efficiency of the solar wafer, thereby generally improving the applicability of the solar wafer and achieving a design concept of lightness and thinness. In addition, the design of the total reflection concentrator concentrates the energy of the sunlight without using the anti-reflection film of the solar wafer.
