Fig. 1 is a schematic diagram of the basic structure of the double-glass solar module of the present invention.

Detailed ways

Referring to FIG. 1 , the double-glass solar module of the present invention includes a surface glass layer 1 , a first adhesive film layer 2 , a solar cell layer 3 , a second adhesive film layer 4 and an inner glass layer 5 connected in sequence.

The surface glass layer 1 and the inner glass layer 5 are tempered glass or plexiglass.

The first adhesive film layer 2 and the second adhesive film layer 4 are polyvinyl butyral resin film layers or ethylene-vinyl acetate copolymer film layers, with a thickness of 0.25 mm or 0.38 mm.

The solar cell layer 3 is composed of multiple solar cells connected in series.

The working principle of the utility model is that the solar cell is composed of a P-type semiconductor and an N-type semiconductor. The N-type semiconductor contains more holes, while the P-type semiconductor contains more electrons. When the P-type and N-type When the semiconductors are combined, a potential will be formed at the junction. When the chip is receiving light, the positively charged holes move to the P-type region, and the negatively charged electrons move to the N-type region. After connecting the wiring and the load, it is create a current.

Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. The key element of this technology is the solar cell. The solar cells are packaged and protected after being connected in series to form a large-area solar cell module, and then cooperate with power controllers and other components to form a photovoltaic power generation device. The advantage of photovoltaic power generation is that it is less restricted by the region, because the sun shines on the earth; the photovoltaic system also has the advantages of safety, reliability, no noise, low pollution, no need to consume fuel and set up transmission lines to generate electricity and supply power on site, and the construction period is short.
