一种抗紫外线光伏玻璃及其应用
摘要：
本发明公开了一种抗紫外线超白光伏玻璃及其应用。该玻璃包括如下重量份的组分：SiO2 72.2-73.0重量份，Al2O3 0.1-1.0重量份、Na2O 14.3-15.3重量份、K2O 0.02-1.2重量份、CaO 9-12重量份、MgO 0.05-4.3重量份、Fe2O3 0.009-0.015重量份、CeO2 0.04-0.16重量份和SO3 0.02-0.18重量份。本发明的超白玻璃中含有0.04-0.16重量份的稀土金属氧化物CeO2，以及添加着色剂0.01-0.05重量份、Co3O4 0-0.1重量份，SrO 0.01-0.5重量份，MnO2 0-0.2重量份，Se 0-0.1重量份，使得该超白玻璃的抗紫外线能力大大提高、紫外线透射率低于55%、光透过率可提高至92%，显著降低了其封装的太阳能晶体硅电池及非晶硅电极板等的紫外线侵蚀作用、延长了太阳能电池组件使用寿命和太阳能电池光电转换效率。
摘要（英）：

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.
