摘要註:	在本研究中，從已最佳化厚度的結構ITO/ CuPc 10nm/ CuPc:C60 (20nm)/ C60 (20nm)/ BPhen (5nm)/ Ag加入陽極緩衝層PEDOT:PSS至ITO與CuPc之間，並藉由摻雜溶劑改善陽極緩衝層PEDOT:PSS，總共嘗試了三種溶劑，分別為山梨醣醇、甘油和DMSO，使得短路電流從5.11 mA/cm2上升到15.45 mA/cm2，開路電壓從0.47V上升到0.51V，轉換效率從1.28%上升到3.37%在AM1.5G的太陽能光譜下。這些增加是歸因於在載子的收集效率、光的吸收效率達到最佳化，此外，使用摻雜3wt%的山梨醣醇的PEDOT:PSS當作陽極緩衝層，能夠導致陽極與主動層接觸更好，使得元件的短路電流及效率獲得大幅改善。為了更進一步改善元件的效率，我們在陰極緩衝層BPhen摻雜碳酸銫，結構為ITO/ PEDOT: PSS (doped with 3wt% sorbitol) / CuPc (10nm)/ CuPc:C60 (20nm)/ C60 (20nm)/ Cs2CO3:BPhen (1:4) (5nm)/ Ag，在此結構下元件效率獲得改善，從未摻雜碳酸銫之元件3.37%上升至3.51%，改善的原因為摻雜碳酸銫後BPhen層能階的變化和表面形貌的改善。 In this study, small molecule organic solar cell with an optimized structure of ITO/ CuPc 10nm/ CuPc:C60 (20nm)/ C60 (20nm)/ BPhen (5nm)/ Ag was fabricated. We incorporated the PEDOT:PSS layer as the anode buffer layer between ITO anode and CuPc layer. We try improving the property of PEDOT: PSS layer by addition of solvent, such as such as sorbitol, glycerol and DMSO. With 3wt% sorbitol-doped PEDOT: PSS layer as the anode buffer layer, the short-circuit current density (Jsc) increased from 5.11 mA/cm2 to 15.45 mA/cm2, the open-circuit voltage (Voc) increased from 0.47 to 0.51 V, and the power conversion efficiency (ηp) increased from 1.28 to 3.37% under 100mW/cm2 AM1.5G illumination. These improvements were attributed to reach the optimal balance among the the carrier collection efficiency, light absorption efficiency, and transmittance of the device. In addition, 3wt% sorbitol-doped PEDOT: PSS layer has been used as buffer layer between CuPc layer and ITO which causes the good contact with the anode. Thus, the incorporation of 3wt% sorbitol-doped PEDOT: PSS layer results in enhancement of Jsc and performance of the device.Based on the optimal structure, we improved BPhen layer doped with Cs2CO3 as cathode buffer layer between the C60 layer and Ag cathode to accelerate the transport of electrons. The small molecule organic solar cell with structure of ITO/ PEDOT: PSS (doped with 3wt% sorbitol) / CuPc (10nm)/ CuPc: C60 mixed (20nm)/ C60 (20nm)/ Cs2CO3:BPhen (1:4) (5nm)/ Ag. The cell with Cs2CO3: BPhen (1:4) layers exhibits power conversion efficiency (PCE) of 3.51% as compared to 3.37% for the device with pristine BPhen layer. The enhanceded PCE in cell was considered as favorable energy level alignment between Cs2CO3: BPhen layer and the fullerene (C60) layer. In addition, the surface morphology is improved by adding Cs2CO3 to BPhen layer.
