摘要

矽是一種高效率的太陽能電池材料，而太陽能電池一直是解決能源問題的熱門議題。混合型太陽能電池結合有機半導體以及無機半導體的優點，本研究選取的p型有機半導體材料為PEDOT:PSS，而n型無機半導體材料則選用Si基板，形成Si/PEDOT:PSS混合型太陽能電池元件。
本實驗有系統地變化一些元件製作參數。我們首先探討在Si基板上原生氧化層的成長時間對於PEDOT:PSS旋塗之影響。其次探討 PEDOT:PSS的旋塗速率及時間對元件光電轉換效率的影響。
本實驗所得到的最佳元件製作參數為4小時原生氧化層成長時間、3000 rpm PEDOT:PSS旋塗速率、以及60 s PEDOT:PSS旋塗時間。以此最佳實驗參數所製作的Si/PEDOT:PSS混合型太陽能電池元件，其效率可達5.811%。

Silicon is a high-performance material for solar cells. The hybrid solar cells combine the advantages of organic solar cells and inorganic solar cells. This study used PEDOT:PSS as the p-type organic semiconductor material and Si substrate as the n-type inorganic material to fabricate hybrid solar cells.
Various device fabrication parameters were investigated systematically. We first discussed the influences of the native oxide forming time on the PEDOT:PSS coating. Then, we studied the influences of PEDOT:PSS coating spin rate and coating time on the device performance.
The optimal device fabrication parameters were found to be a native oxide forming time of 4 hr and the PEDOT:PSS coating spin rate and time of 3000 rpm and 60 s, respectively.
The Si/PEDOT:PSS solar cell based on the optimal fabrication parameters has exhibited a power conversion efficiency of 5.811%.
