Description

Solar battery module

The present invention relates to a solar cell module, and particularly relates to an innovative designer who directly sets a circuit on a substrate to form a connection with a solar cell to achieve a reduction process.

According to the solar cell, it is also called a "solar chip" or a photovoltaic cell. It is an optoelectronic semiconductor chip that directly generates electricity by using sunlight, and can output voltage and current as long as it is illuminated.

Solar cell power generation is based on the photoelectric properties of a particular material, radiating electromagnetic waves of different wavelengths (corresponding to different frequencies), such as red, ultraviolet, visible light, and the like. When these rays are irradiated on different conductors or semiconductors, the photons react with free electrons in the conductor or semiconductor to generate a current. The shorter the wavelength of the ray, the higher the frequency, the higher the energy, for example, the energy of ultraviolet light is much higher than that of infrared ray. However, not all wavelengths of energy can be converted into electrical energy, and its photoelectric effect is independent of the intensity of the radiation. Current can only be generated when the frequency reaches or exceeds the photoelectric effect.

The assembly method of the existing solar cell module, as shown in the fourth to fifth figures, mainly includes a back plate (61), a first encapsulating material layer (62), a solar cell (63), and a second encapsulating material. The layer (64) and a cover plate (65) are disposed between the back plate (61) and a cover plate (65), and then coated with the first and second encapsulating material layers ( 62), (64) [material such as EVA material], vacuum is drawn inside the first and second encapsulating material layers (62), (64) through a lamination operation, and then the solar cells (63) and the back plate are 61) The cover plate (65) and the first and second encapsulating material layers (62) and (64) can be tightly combined to complete the fabrication of the solar cell module (6). The solar cell (63) is formed by a plurality of positive terminals and a plurality of negative terminals respectively on the upper and lower end faces of the semiconductor, and each of the positive and negative ends is connected in series with each other by a wire (631). A solar cell (63) is fabricated, and then the solar cell (63) is packaged with the back plate (61) and the cover plate (65). It can be seen that the circuit of the solar cell (63) is complicated to manufacture, resulting in an overall solar cell module. (6) It is impossible to produce quickly.
