[0002] The future development of energy should follow the path of sustainable development. The society's demand for renewable energy is increasing continuously. As a clean energy technology, photovoltaic power generation has gradually attracted wide attention.

[0003] Current photovoltaic power generation devices mostly use solar photovoltaic power generation. However, this power generation method requires direct sunlight, and photovoltaic power generation is affected by weather conditions. For example, on cloudy days or at night, with insufficient light, the power generation efficiency will decrease.

[0004] Regarding the technology of generating electricity through light energy, so far, there has been no technology that can solve this technical problem. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: to solve the deficiency that the existing power generation method depends on the presence of sunlight, and thus provide a power generation device that irradiates a photovoltaic silicon wafer with specific light.

[0006] The technical solution adopted by the present invention to solve its technical problems is:

[0007] A power generation device that irradiates a photovoltaic silicon wafer with specific light, including a first conductive strip, a first photovoltaic silicon wafer, a first light guide film, a first light-transmitting plate, a second light guide film, a second photovoltaic silicon wafer, and a second conductive strip arranged in sequence. The outer side of the first light-transmitting plate is provided with a light source that can cooperate to generate the photovoltaic effect. It can be that light sources one are provided on all four sides, or one side / two sides / three sides have light sources one.

[0008] Further, the first light guide film and the second light guide film are respectively deposited on the outer surfaces of the first photovoltaic silicon wafer and the second photovoltaic silicon wafer by physical vapor deposition technology.

[0009] Further, the light source one is one or a combination of ultraviolet lamps, infrared lamps, and incandescent lamps.

[0010] Further, the specific light irradiates the photovoltaic silicon wafer through a light guide plate and a light guide film, causing the silicon wafer to generate electron-hole pairs. Using the built-in electric field, the electrons and holes are separated to generate current and a potential difference, realizing the conversion of light energy into electrical energy.

[0011] Further, both the first conductive strip and the second conductive strip are composed of a plurality of conductive strips, and one of the plurality of conductive strips is used to connect the other conductive strips for conduction.

[0012] The beneficial effects of the present invention are:

[0013] 1. The product of the present invention supplies light source through ultraviolet lamp or infrared lamp or incandescent lamp, replacing direct sunlight, not restricted by weather, enabling the photovoltaic silicon wafer to generate electricity, and finally forming current and voltage after connecting the conducting bar to the wire.

[0014] 2. Moreover, it is set to generate electricity with double - layer photovoltaic silicon wafers, and the same light source can generate double current and voltage, with high - efficiency power generation.

[0015] 3. The structure of the product of the present invention is exquisitely designed. Since the structure is not restricted by direct sunlight, the position is not restricted, and its size can also be adjusted arbitrarily. It can be placed in some relatively casual spaces, saving resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Embodiment 1

[0027] Combined with Figures 1-3 , this embodiment provides a power generation device that irradiates a photovoltaic silicon wafer with specific light, including a first conductive strip 100, a first photovoltaic silicon wafer 200, a first light guide film 300, a first light transmissive plate 400, a second light guide film 500, a second photovoltaic silicon wafer 600, and a second conductive strip 700 arranged in sequence. Light sources 800 capable of cooperating to generate the photovoltaic effect are provided around the first light transmissive plate 400.

[0028] The first light transmissive plate 400 can be glass, which is used to guide the light of the light source 800. The light sources 800 are arranged around it, so that the first light transmissive plate 400 guides the light evenly and transmits the light evenly to the first photovoltaic silicon wafer 200 and the second photovoltaic silicon wafer 600 on both sides. Of course, the light sources 800 can also be arranged on only one side, or two sides, or three sides; both the first light guide film 300 and the second light guide film 500 are respectively deposited on the outer surfaces of the first photovoltaic silicon wafer 200 and the second photovoltaic silicon wafer 600 by physical vapor deposition technology. Of course, other connection processes that do not affect light guiding can also be selected.

[0029] The light source 800 is one or a combination of an ultraviolet lamp, an infrared lamp, and an incandescent lamp. Both the first conductive strip 100 and the second conductive strip 700 are composed of a plurality of conductive strips, and one of them is used to connect the other conductive strips. The conductive strips are evenly arranged on the outer surfaces of the first photovoltaic silicon wafer 200 and the second photovoltaic silicon wafer 600.

[0030] The first photovoltaic silicon wafer 200 and the second photovoltaic silicon wafer 600 can be made of main materials such as silicon + boron, or can also be silicon + phosphorus, silicon + boron + tellurium, or silicon + phosphorus + tellurium.

[0031] When the present invention is specifically used:

[0032] The ultraviolet lamp, infrared lamp, or incandescent lamp located outside the light-transmitting plate supplies the light source. The photovoltaic silicon wafer absorbs light energy through the light-transmitting plate, causing electron-hole pairs to be generated in the silicon wafer. Using the built-in electric field to generate a potential difference, current is thus generated, and the current is conducted out through the conductive strip connecting the wire.

The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
