摘要

以C60之衍生物PCBM和P3HT互相共混於鄰-二氯苯溶劑中24小時，並將調配好之溶劑，利用旋轉塗佈機均勻塗佈於Glass/ITO/PEDOT:PSS上，作為高分子太陽能電池之主動層。實驗數據以獲得最佳功率轉換效率，包括混合有機溶劑、電洞傳輸層、電子傳輸層、主動層之旋轉塗佈轉速、主動層乾燥時間及慢成長期間對溶液與基板的加熱溫度與時間等等。第一部份，主動層乾燥的處理方法是利用自組織效應改善元件串聯電阻及載子移動率問題，探討慢成長期間同時對鄰-二氯苯溶液與基板加熱對自組織效應之慢成長處理的影響，藉由鄰-二氯苯溶劑溫度控制飽和蒸汽壓。第二部份，在主動層薄膜上面，比較蒸鍍不同的有機材料，分別探討對元件的開路電壓與短路電流的影響。

The derivative of C60, [6,6]-phenyl C61-butyric acid methyl ester( (PCBM), and 3-hexylthiophene (P3HT) were dissolved in o-Dichlorobenzene (DCB) solvent 24 hours, then spin-coated in Glass/ITO/PEDOT:PSS as active layer for polymer solar cells. The experimental parameters were studied carefully to obtain the optimum power conversion efficiency (PCE), including the mixing organic solution, hole transport layer, electronic transport layer, spin-coating speed of active layer, drying conditions of active layer, the solution and substrate heating temperature and time on slow growth process etc. First part, the active layer of dry treatment method to use organize effect improve component series resistance and carrier mobility, heat the solution and substrate to self-organizing on the influence during slow growth process. Second parts, evaporate material at the active layer, comparison of evaporate different to organic materials, discuss the influence to improving in open voltage and short current of the organic solar cells.
