dc.description.abstract | Organic photovoltaic devices fabricated from small molecular donors continue to receive significant interest due to their desirable properties such as convenient synthesis, purification and batch-to-batch reproducibility. In this study, we have synthesized two small molecules based on an alternating A-D-A structure, utilizing a central EDOT donor moiety and either 2-ethylhexyl cyanoacetate ( SAM-80 ) or N-(2-ethylhexyl)cyanoacetamide ( SAM-72 ) units as acceptor termini. The small molecules were incorporated into bulk heterojunction solar cells with PC71BM . Our investigations have shown that the side chains utilized for SAM-80 only allow for solution processing using volatile solvents, such as chloroform, which limits the reproducibility of device fabrication. However, SAM-72 displays better solubility and devices fabricated using a SAM-72:PC71BM active layer reached average power conversion efficiencies of 1.9%, with fill factors reaching 60%. Post-processing methods such as thermal and solvent vapor annealing were found to significantly increase the stability of devices, but were not able to improve overall device performance. | |
