摘要：
Small molecule organic solar cell with an optimized structure of indium tin oxide (ITO)/poly (3,4-ethylenedioxythioxythiophene): poly (styrenesulfonate) (PEDOT: PSS) doped with three solvents, respectively/copper phthalocyanine (CuPc) (10 nm)/CuPc: fullerene (C-60) mixed (20 nm)/C-60 (20 nm)/bathocuproine (BCP) (10 nm)/Ag was fabricated. In this study, the electrical characterization, morphology and optical quality on photovoltaic devices with different solvent-doped PEDOT: PSS layers were discussed. The addition of solvent results in the decided improvement in short-circuit current (J(sc)) and fill factor (FF). It is found that the 3 wt% sorbitol-doped PEDOT: PSS film has the optimal quality. The maximum power conversion efficiency (PCE) of 3.37% was obtained under 1sun standard AM 1.5 solar illumination of 100 mW/cm(2). (C) 2013 Elsevier B.V. All rights reserved.
