Paper Abstract

Charge carrier losses of organic solar cells (OSCs) based on Subphthalocyanine (SubPc)/C60 heterojunction have been studied through the measurements of incident light intensity dependent response of the device. The light intensity was varied between 0.03 and 100 mW/cm2. The results showed that short circuit current density follows a linear dependence on light intensity (Pin), while open circuit voltage logarithmically increase with Pin with a slop of 120 mV/decade, indicating that the charge carrier losses are governed by trap-assisted recombination through interface states between donor and acceptor, with an estimated trap density of order 1024 m-3. Moreover, the inverse dependence of shunt resistance (RPA) on light intensity reveals that charge carriers are trapped in the bulk of active layer as well as at the organic/electrode interface, resulting in the decrease of fill factor (FF) with Pin.
