The fullerene solar cells are becoming a feasible choice due to the advanced developments in donor materials andimproved fabrication techniques of devices. Recently, sufficient optimization and improvements in the processingtechniques like incorporation of solvent vapor annealing (SVA) with additives in solvents has become a majorcause of prominent improvements in the performance of organic solar cell-based devices . On the other hand, thechallenge of reduced open circuit voltage (Voc) remains. This study presents an approach for significant performanceimprovement of overall device based on organic small molecular solar cells (SMSCs) by following a two steptechnique that comprises thermal annealing (TA) and SVA (abbreviated as SVA+TA). In case of exclusive use of SVA,reduction in Voc can be eliminated in an effective way. The characteristics of charge carriers can be determined bythe measurement of transient photo-voltage (TPV) and transient photo-current (TPC) that determines the scopefor improvement in the performance of device by two step annealing. The recovery of reduced Voc is linked with thenecessary change in the dynamics of charge that lead to increased overall performance of device. Moreover, SVAand TA complement each other; therefore, two step annealing technique is an appropriate way to simultaneouslyimprove the parameters such as Voc, fill factor (FF), short circuit current density (Jsc) and PCE of small molecular solarcells.
