碩士 === 義守大學 === 電子工程學系碩士在職專班 === 100 === In this study, small molecule organic solar cells (OSCs) have been fabricated and characterized. Copper(Ⅱ) phthalo-cyanine (CuPc) and fullerene (C60) are adopted as an active layer in OSCs. Experimental results reveal that inserting the LiF layer between the cathode and bathocuproine (BCP) can effectively enhance the electron transfer from the active layer to cathode. The short-circuit current density (Jsc) is enhanced and power conversion efficiency (PCE) is increased from 0.3% to 0.36%. In addition, V2O5 is used as a hole transporting layer between the active layer and anode in OSCs. OSCs in the optimized structure of ITO/V2O5/CuPc/C60/BCP/LiF/Al exhibit open circuit voltage (Voc) of 0.4 V, Jsc of 2.4 mA/cm2, fill factor (F.F.) of 54.08%, and PCE of 0.51% at AM 1.5G of 100 mW/cm2.
