Problems solved by technology
[0003] The power generation of solar cell components mainly depends on the energy conversion of sunlight. The wavelength distribution of sunlight is wide, from 280nm to 1150nm, but the wavelength that really has an important impact on the power generation of cells is between 550nm and 850nm (this is determined by each company's related to the cell process), while the ultraviolet light before 550nm and the infrared light after 850nm do not contribute much to the power generation of the cell, thus reducing the absorption of sunlight by the solar cell module, which in turn affects the conversion efficiency of the solar cell module

The invention discloses a solar cell module and a manufacturing technique thereof. The solar cell module comprises a transparent upper cover board, a first adhesive layer, a solar cell piece, a second adhesive layer and a backboard which are stacked in sequence, an anti-reflection layer coats the surface of the transparent upper cover board, the anti-reflection layer comprises silicon oxide and zirconium dioxide, the mass ratio of the zirconium dioxide to the silicon oxide is 5: 4 to 7: 2, and the anti-reflection layer is 100 to 150 nanometers in thickness. Compared with the prior art, the solar cell module uses the mixture of the silicon oxide and the zirconium dioxide as the anti-reflection layer, the light of ultraviolet bands and infrared bands can be converted into wavelengths capable of being completely used by the solar cell piece by means of the wavelength conversion characteristic of the metal oxide-zirconium dioxide, and accordingly the light transmittance of the visible light is increased, and the cell conversion efficiency is improved.
Description
technical field [0001] The invention relates to a solar cell assembly, and also relates to a manufacturing process of the solar cell assembly. Background technique [0002] At present, the solar cell module is coated with an anti-reflection film on the front cover glass to reduce the reflection of sunlight, so as to achieve the function of increasing the conversion efficiency of the module. The coating material of the anti-reflection film is mainly silicon-based oxide, and the thickness is generally controlled between 100-150nm, which can be adjusted according to the requirements of the process and product. [0003] The power generation of solar cell components mainly depends on the energy conversion of sunlight. The wavelength distribution of sunlight is wide, from 280nm to 1150nm, but the wavelength that really has an important impact on the power generation of cells is between 550nm and 850nm (this is determined by each company's related to the cell technology), while th...
