摘要註:	在本研究中，最佳化結構是從一般常用的結構ITO/CuPc (20nm)/C60 (30nm)/BCP(10nm)/Al調整元件主動層的厚度與結構，使得短路電流3.09 mA/cm2上升到5.11 mA/cm2，開路電壓從0.4V上升到0.47V，轉換效率從0.66%上升到1.28%在AM1.5G的太陽能光譜下。這些增加是歸因於在光的吸收效率和載子的分離效率以及載子的收集效率之間達到一個最佳的平衡，使得短路電流能有所提升而不會影響到元件的填充因子的值。最後得到有機太陽能電池最佳化結構為：ITO/CuPc (10nm)/CuPc:C60 (20nm)/C60 (20nm)/BCP(10nm)/Al。。為了更進一步地增加元件的效率，我們在最佳化結構的基礎下，在ITO及CuPc之間插入PEDOT: PSS(有摻雜sorbitol)與pentacene雙層陽極緩衝層來幫助元件電洞的收集效率，元件的結構為ITO/PEDOT: PSS (doped with 4wt% sorbitol)/ pentacene (2nm)/CuPc (10nm)/ CuPc: C60 mixed (20nm)/C60 (20nm)/BCP (10nm)/Al。因此藉由雙層陽極緩衝層插入元件使得轉換效率大幅度的增加。短路電流提升了三倍之多，使得元件的轉換效率達到3.9%。 In this study, small molecule organic solar cell with an optimized structure of ITO/CuPc 10nm/CuPc:C60 (20nm)/C60 (20nm)/BCP (10nm)/Al) was fabricated. With optimizing the above structure from the conventional structure of ITO/CuPc (20nm)/C60 (30nm)/BCP (10nm)/Al, the short-circuit current density (Jsc) increased from 3.09 mA/cm2 to 5.11mA/cm2, the open-circuit voltage (Voc) increased from 0.40 to 0.47V, and the power conversion efficiency (ηp) increased from 0.66 to 1.28% under 100mW/cm2 AM1.5G illumination. These improvements were attributed to reach the optimal balance among the light absorption efficiency, the exciton dissociation efficiency and the carrier collection efficiency of the device, resulting in enhancement of Jsc without affecting the value of fill factor (FF) and the reduction of the dark current.Based on the optimal structure, we incorporated PEDOT: PSS layer doped with 4wt% sorbitol and pentacene layer as interlayers between the ITO anode and CuPc layer to help the hole transport. The small molecule organic solar cell with structure of ITO/PEDOT: PSS (doped with 4wt% sorbitol)/ pentacene (2nm)/CuPc (10nm)/ CuPc: C60 mixed (20nm)/C60 (20nm)/BCP (10nm)/Al. And then the short-circuit current (Jsc) of solar cell was enhanced by inserting both the PEDOT: PSS (4wt% sorbitol) and the pentacene, resulting in a 300% enhancement in power conversion efficiency (PCE). The maximum PCE of 3.9% was obtained under 1sun standard AM1.5G solar illumination of 100mW/cm2.
