在此研究中，我們結合了非晶矽材料及微晶矽材料的優點，提出了一個新穎的單接面薄膜太陽能電池架構 「 ITO / p-a-Si:H / i1-a-Si:H / i2-μc-Si:H / n-μc-Si:H / ITO 」。其中i1-a-Si:H層為非晶矽材料，因其移動率能隙較大的緣故，可提升整體的開路電壓；而i2-μc-Si:H層為微晶矽材料，可以吸收太陽光較長部分的波長，以增加電子電洞對的產生，增進短路電流密度，進而提升太陽能電池的轉換效率。此新穎單接面薄膜太陽能電池架構之模擬結果，相較於傳統的單接面矽薄膜太陽能電池可提高8.8 %到19.5 %的轉換效率。另外，為了因應低成本、高效能太陽能電池的發展趨勢，我們提出了一個新穎的薄膜太陽能電池製程方式，於相同的時間內，同時兩面沉積矽薄膜太陽能電池，自然形成一背對背類並聯型的矽薄膜太陽能電池。經過模擬後顯示，類並聯的非晶矽薄膜太陽能電池相較於傳統的非晶矽薄膜太陽能電池可提高約39.8 %的轉換效率，而類並聯的微晶矽薄膜太陽能電池相較於傳統的微矽薄膜太陽能電池也可提高約16 % 的轉換效率。經過實際製程驗證後，類並聯的非晶矽薄膜太陽能電池相較於傳統的非晶矽薄膜pin太陽能電池，可提高25.6 %到31.5 %的轉換效率。

In this work, combining the advantages of amorphous silicon and microcrystalline silicon, we propose a new structure of solar cell “ ITO / p-a-Si:H / i1-a-Si:H / i2-μc-Si:H / n-μc-Si:H / ITO ”. The i1-a-Si:H can make the open circuit voltage much higher due to the high mobility bandgap. The i2-μc-Si:H can get more effectively absorb of sunlight, so the novel p-i1-i2-n solar cell can get higher short circuit current density. The simulation results indicate the conversion efficiency is higher than that of the conventional silicon solar cell at least 8.8 % to 19.5 %. In order to obtain low-cost and high-performance solar cell, a novel thin film solar cell fabrication has been developed. In this way, the deposition of silicon thin film solar cells on both sides of the substrate is performed at the same time, forming a back-to-back parallel-type silicon thin film solar cell naturally. The simulation results indicate the conversion efficiency of the back-to-back parallel-type amorphous silicon thin film solar cell is higher than that of the conventional amorphous silicon thin film solar cell at least 39 %. And the conversion efficiency of the back-to-back parallel-type microcrystalline silicon thin film solar cell is higher than that of the conventional microcrystalline silicon thin film solar cell at least 16 %. The fabrication results also indicate the conversion efficiency is higher than that of the conventional pin amorphous silicon solar cell at least 25.6 % to 31.5 %.
