硫气氛下热处理后太阳能玻璃减反膜的透过率稳定性

Transmittance Stability of Solar Glass Antireflective Coating Prepared by Heat-treating in Sulfur Atmosphere

太阳能镀减反膜玻璃作为太阳能电池盖板玻璃,需要长期暴露于室外,因此了解太阳能玻璃减反膜的透过率及其稳定性具有重要意义。本文主要研究了在一定湿度和一定温度环境下,硫气氛下和未通入硫气氛下热处理后的太阳能玻璃减反膜透过率的变化。通过岛津UV-3600测定了玻璃的透过率;利用Nexus傅里叶变换红外光谱仪和INVIA显微共焦拉曼光谱仪测定了太阳能玻璃减反膜的结构。研究结果表明:太阳能玻璃减反膜的透过率稳定性与不同气氛下热处理后的结构有关;在水侵蚀作用下,减反膜的透过率与水的结合类型有关。

Solar glass coated by antireflective film,as a cover of the solar cell,usually exposes to outdoor for a long time.Therefore,it is of great significance to understand the transmittance and stability of the solar glass antireflective coating.In this paper,transmittance of solar glass antireflection cootings was studied,and the transmittances were compared between the glasses prepared with and without heat treatment at certain temperature and humidity.The transmittance was measured by SHIMADZU UV-3600 spectroscopy,and the structure of antireflection coating was tested by FT-IR and Raman spectroscopy.The result shows that the solar transmittance stability is related to the structure of the antireflection coating prepared by different heat-treating process,and the transmittance is affected by type of bound water in water erosion.
