1. 毕业设计(论文)的内容和要求
带有本征层的n型异质结(hit)太阳能电池结合了晶硅和非晶硅薄膜电池的两者优点,保证了较高的电池转换效率,同时采取低温生产工艺,降低了成本,还避免了电池的光致衰退效应,具有较好的稳定性。
不过,电池发射结p型非晶硅薄膜对入射太阳光有较强的吸收,因此寻找合适的不吸收或弱吸收的替代材料作为p型发射层来提高电池效率显得十分关键。
本课题将采用功函数较高的氧化钼(moox)层作为p层来降低光吸收,利用afors-het仿真软件对含有moox层的hit电池(ito/moox/i-a-si/n-c-si/i-a-si/n -a-si/ito)的性能进行系统研究,寻求最佳器件结构,为n型异质结太阳能电池的优化工艺提供有价值的思路。
