Abstract

The invention discloses solar cell glass. The solar cell glass is prepared from, in parts by weight, 60-80 parts of a glass substrate, 0.5-1.5 parts of an activator, 1-3 parts of a sensitizer and 5-15parts of an oxidant, wherein the glass substrate is prepared from, in parts by weight, 72-79 parts of SiO2, 5-14 parts of CaO, 10-16 parts of Na2O, 1.5-6 parts of MgO and 0.5-3 parts of Al2O3. According to the solar cell glass, since a small quantity of the activator is added, the efficiency of energy transfer of the solar cell glass can be increased, the heat absorption of the solar cell glass can be reduced, and the light transmittance of the solar cell glass can be improved; meanwhile, through the addition of a small quantity of the sensitizer, the solar cell glass can be more sensitive tolight, so that light transmission through glass is facilitated, and the light transmittance of the solar cell glass is increased; the solar cell glass can be applied to the field of manufacture of solar cell glass.

Description

technical field

[0001] The invention relates to the field of solar energy, in particular to solar battery glass. Background technique

[0002] A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. Crystalline silicon solar cells that work on the photoelectric effect are the mainstream, while thin-film solar cells that work on the photochemical effect are still in their infancy. The glass of solar cells is required to have excellent light transmittance and corrosion resistance as the main body of power generation (such as cells) for protection.

[0003] At present, the light transmittance of glass produced by my country's glass manufacturers is not high, resulting in the overall quality lagging far behind developed countries. Imports lead to high cost of solar power generation and seriously affect the development of my country's solar industry. Therefore, further improvement of solar cell...
