Problems solved by technology

[0003] Glass is often used as a packaging material in solar cell components to prevent the crystalline silicon or amorphous silicon components from aging under ultraviolet radiation and shorten their service life, but the UV transmittance of the packaging glass in the prior art is still High, unable to effectively resist the damage of ultraviolet rays to crystalline silicon or amorphous silicon components
In addition, the ultra-clear glass in the prior art has a relatively low transmittance, does not absorb a large amount of sunlight enough, and has defects such as low photoelectric conversion efficiency of solar cells.

Abstract

The invention discloses an ultraviolet-resistant super-white solar photovoltaic glass and applications thereof. The ultraviolet-resistant solar photovoltaic glass comprises following ingredients, by weight, 72.2 to 73.0 portions of SiO2, 0.1 to 1.0 portion of Al2O3, 14.3 to 15.3 portions of Na2O, 0.02 to 1.2 portions of K2O, 9 to 12 portions of CaO, 0.05 to 4.3 portions of MgO, 0.009 to 0.015 portion of Fe2O3, 0.04 to 0.16 portion of CeO2 and 0.02 to 0.18 portion of SO3. The super-white-light solar photovoltaic glass comprises 0.04 to 0.16 weight portion of rare-earth metal oxide CeO2, 0.01 to 0.05 weight portion of a coloring agent, 0 to 0.1 weight portion of Co3O4, 0.01 to 0.5 weight portion of SrO, 0 to 0.2 weight portion of MnO2, and 0 to 0.1 weight portion of Se, so that ultraviolet resistance of the super-white-light solar photovoltaic glass is increased greatly, ultraviolet transmissivity is less than 55%, light transmissivity is increased to 92%, and the super-white-light solar photovoltaic glass is capable of reducing ultraviolet erosion effect on solar crystalline silicon cells and noncrystalline silicon plate electrodes made of the super-white-light solar photovoltaic glass, prolonging service life of solar battery assemblies, and increasing photoelectric conversion efficiency of solar batteries.
