  本研究主要探討異質接面太陽能電池的結構,即是在單多晶矽晶圓基板的正反面沉積非晶矽薄膜而形成異質接面太陽能電池。此結構結合了單晶矽太陽能電池的高穩定性及高效率和非晶矽太陽能電池的高吸光率的優點;在製程方面較容易、且在較低溫的環境下製作以及製程所需時間較短,達到較低成本的效果。我們是利用Silvaco公司的TCAD模擬軟體探討以n型單晶矽為基板的異質接面太陽能電池中的非晶矽材料及接面處的參數對於其輸出效率的影響。然後,優化其中的參數,以達到最高效率的異質接面太陽能電池。
  This study involves the novel heterojunction with intrinsic thin layer (HIT) solar cell structure. Combining the advantages of both crystalline silicon and amorphous silicon, a new structure of silicon-based solar cell was proposed - the heterojunction with an intrinsic thin layer (HIT) solar cell. It has high stability and large light absorption coefficient. It is manufactured under low temperature deposit process, which results in a low cost thin film HIT solar cell with high conversion efficiency. The influence of various layer materials and interfaces on the performance of n-type c-Si based bifacial HIT solar cell has been investigated by using the Silvaco TCAD simulation software. Accordingly, the design optimization of HIT solar cell was proven.
