太阳能电池窗口层的制备及其转换效率的研究

Research on the Preparation and Conversion Efficiency of Solar Cell Window Layer

摘要: 将纳米金刚石粉末、乙基纤维素按一定的质量比混合后加入溶剂制成纳米金刚石浆料。用玻璃棒将溶胶滴在固定在溶胶凝胶甩胶机的超白玻璃上，溶胶凝胶甩胶机3000转/分甩胶成膜，再经过热烧结后得到透明的纳米金刚石薄膜。将烧结好的薄膜玻璃作为太阳能电池的窗口层，通过I-V特性测试系统测试其转换效率、影响因子等。并与未镀膜洁净的、未镀膜户外放置一段时间、镀膜户外放置一段时间的太阳能电池的各项数据进行对比分析。最后得出在太阳能电池表面制备纳米金刚石透明薄膜有自清洁功能，可以提高太阳能电池转换效率。Nano-diamond slurry was got by mixing with nano-diamond powder, ethyl cellulose and solvent in a certain quality. Then the mixed solvent was dropped on ultra-white glass which fixed on sol-gel glue rejection machine. The machine was set 3000 r/min to get film. At last, nano-diamond film was got by sintering. Sintered glass was treated as the window layer of solar battery, and then the conversion efficiency and the impact factor were tested through the I-V characteristics system. The different solar cells were contrasted and analyzed. So nano-diamond film’s self-cleaning function can be got. What’s more, it can improve the conversion efficiency of the solar cell.
