Embodiment

[0149] experiment method

[0150] 1. Fabrication of solar panels

[0151] The polymer sheet used to form the encapsulant layer was prepared by the method described in the present invention, and according to figure 1 The structure shown is packaged into a battery. The process used for solar cell module packaging includes cell sorting, single welding, string welding, stacking, lamination, framing and cleaning.

[0152] 2. The output power test method of solar panels

[0153] The solar cell panel manufactured by the above method was tested by a 3500SLP component tester (purchased from Spire Company of the United States) to obtain the output power value.

Abstract

The invention discloses a solar panel. The solar panel comprises a back plate, a front plate, an encapsulating material and a solar cell circuit in the encapsulating material, wherein a wavelength shifter is mixed in the encapsulating material; and the wavelength shifter can effectively shift an ineffective or low-efficiency sunlight wavelength to an effective wavelength.

Description

technical field [0001] The invention relates to a high-performance solar panel, which has high photoelectric conversion efficiency and thus high output power. The invention also relates to a method of manufacturing this new type of solar panel. Background technique [0002] With the warming of the global climate and the high price of carbonized fuels, the governments of various countries have higher and higher requirements for energy conservation and emission reduction. Therefore, finding new energy sources to replace fossil fuels has become an urgent problem to be solved. [0003] Solar energy is a clean, pollution-free and inexhaustible source of energy. At present, solar energy is mainly converted into electrical energy through solar panels, which is then used to drive electric water heaters, electric vehicles, satellite components, etc. [0004] A solar panel is a photoelectric element that directly generates electricity from light, especially sunlight. Existing crys...
