臺灣博碩士論文加值系統

奈米尺度太陽能電池在近期太陽能電池發展中因許多新物理概念及應用的加入被視為達成高效率元件的新發展目標。以往較薄的太陽能電池因吸收長度較短，使得不少能量在傳遞的過程中散失，造成其效率較傳統的太陽能電池相對較低。但在電漿效應、光的捕捉等許多新的設計加入其中後，使奈米太陽能電池可以達到更高的表現，加上新的製程技術可以降低基板的損耗及較薄的電池可減少材料的使用，使得奈米尺度太陽能電池在未來的發展中展現十足的潛力。
我們利用Matlab軟體建立數值模型。對一般較大尺度的元件我們採用基本半導體公式進行模擬，成功的分析了我們再p-i-n結構中的本質層的漸變及陡變能隙的設計。在奈米尺度結構中，部份基本公式已不再適用，利用更一般性的物理描述，我們建立了新的模擬平台。利用此數值分析模型，奈米尺度太陽能電池的特性得以被研究。
