| 采用溶胶-凝胶法制备了SiO2 和TiO2 纳米溶胶，采用水热法制备了石墨烯量子点（graphene quantum dots，GQDs）。为进一步提高光伏太阳能板的透光率，设计了一种TiO2/SiO2/GQDs双层增透膜结构。探究了薄膜的结构、自清洁性能和增透性能，并进一步讨论了GQDs在增透性中的作用。结果表明，SiO2-TiO2/TiO2-GQDs结构的双层薄膜厚度为120 nm时，太阳能板上的光透过率由未涂敷的85%增加至95%。接触角实验和室外耐环境性能实验测试表明，复合膜层接触角为10°，并具有良好的亲水性和耐环境性能。此外，户外实验结果表明，涂覆该薄膜的太阳能电板发电效率提高6%。由此说明双层增透膜可有效地提高太阳能电池板的光能利用率和使用寿命，可高效地利用太阳能。 |
| 英文摘要: |
| The TiO2 and SiO2 sol-gels were prepared by sol-gel method, and the graphene quantum dots (GQDs) were prepared by hydrothermal method. In order to further enhance the light transmittance of photovoltaic solar panels, a TiO2/SiO2/GQDs double-layer antireflective film was designed. The microstructure, self-cleaning property and antireflection property of the films were investigated, and the function of GQDs for antireflection was further discussed. The results show that when the thickness of the SiO2-TiO2/TiO2-GQDs double-layer film is 120 nm, the light transmittance of the solar panel increases from 85% under uncoated condition to 95%. The double-layer film exhibits a contact angle of 10° and shows good hydrophilicity and environmental resistance. The efficiency of the film-coated photovoltaic solar panel is increased by 6%, indicating that the double-layer antireflective film can effectively improve the solar energy utilization rate and service life of solar panels. |
