梯度掺杂发射层对p型HIT电池性能影响的理论研究任务书

 2020-05-01 08:48:30  

1. 毕业设计(论文)的内容和要求

带有本征层的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。

最近五年hit电池发展很快,最高转换效率已经达到26.6%,离理论极限效率29%很接近,目前如何进一步提高电池效率就会很难。

本课题将采用梯度掺杂发射层来替代传统的均匀掺杂层来提升电池效率,利用afors-het仿真软件对含有梯度掺杂发射层的hit电池性能进行系统研究,寻求最佳器件结构,为p型hit太阳能电池的优化工艺提供有价值的思路。
