Problems solved by technology

Most of the existing technologies use flat-panel solar panels. Although this type of solar panel can well adapt to changes in the incident angle of the sun, its electrical conversion rate is low, and silicon materials are used more, resulting in higher production costs.

Abstract

The invention relates to a light-focusing solar cell panel, and the solar cell panel is provided with toughened glass located at the upper layer, a battery piece located at the central layer and a backboard located at the bottom layer. Ethylene and vinyl acetate copolymer adhesive films are disposed between the toughened glass and the battery piece and between the battery piece and the backboard. The toughened glass, the battery piece, the backboard and the ethylene and vinyl acetate copolymer adhesive films are pressed and bonded into one body through vacuum heating. According to the invention, the battery piece is disposed between the toughened glass and the backboard, thereby effectively preventing the battery piece from contacting with the outside, and prolonging the service life. A PN junction of the solar cell panel is shaped like a ball, can receive the sunlight to maximum degree, can eliminate the aberration of sunlight spots under the condition that the incident angle of the sun changes, and improve the photoelectric conversion rate. According to the invention, the PN junction of the solar cell panel is shaped like the ball, and there is no need of cutting operation, thereby greatly reducing the material loss. The usage amount of materials is one fifth of the usage amount of materials of a flat-type solar cell, thereby reducing the production cost.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a concentrated solar cell panel. Background technique [0002] At present, the traditional fuel energy is decreasing day by day, and the harm to the environment is becoming more and more prominent. At the same time, there are still 2 billion people in the world who do not have normal energy supply. At this time, the whole world is turning its attention to renewable energy, hoping that renewable energy can change the energy structure of mankind and maintain long-term sustainable development. Among them, solar energy has become the focus of people's attention due to its unique advantages. Abundant solar radiation energy is an important energy source, which is inexhaustible, non-polluting, cheap, and can be freely utilized by human beings. The energy of solar energy reaching the ground every second is as high as 800,000 kilowatts. If 0.1% of the solar energy on the earth's sur...
