纳米TiO_2对船用太阳能电池板玻璃盖片光学性能的影响

Influence of nanometer titanium dioxide on optical property of marine solar panel cover-glass

船用太阳能电池板长期处于含大量腐蚀性物质且十分潮湿的海洋环境中,因此极易产生表面缺陷,影响其光学性能,从而极大地降低船用太阳能电池板的工作效率。而纳米TiO_2涂层在一般环境中具有较好的防腐蚀及疏水性能及一定的自洁能力,如能将其应用于船用太阳能电池板玻璃盖片,则可缓解上述问题。为尝试将其应用于船舶太阳能电池板玻璃盖片,分别采用3种不同的方法制备了纳米TiO_2涂层的玻璃盖片试样,并用紫外分光光度计测定各块试样的透射比。结果表明,采用刮涂法制备的盖片试样光学性能最佳,且与普通玻璃盖片相近甚至更大。

Marine solar panels are in the complicated marine environment chronically where is very humid and contains large quantities of corrosive substances,so they are easily corroded.Thereby optical performance and photoelectric conversion efficiency of marine solar panels will be affected to a large extent.Nanometer titanium dioxide coating possesses superior anticorrosion performance,hydrophobicity and certain characteristic of selfcleaning in general environment.If it can be applied to marine solar panels,this problem can be alleviated.In order to apply nanometer titanium dioxide coating to marine solar panel cover-glass,cover-glass samples with nanometer titanium dioxide coating in general environment were prepared using 3different methods.Then the transmittance of each sample was measured by ultraviolet spectrophotometer.And the results show that coverglass samples with nanometer titanium dioxide coating which are prepared by method of scrape coating have the best optical property,and their optical property is similar to or even better than general cover-glasses.
