| Abstract | Abstract Non-fullerene electron-acceptor is an interesting class for advancement in organic solar cells. We herein report design and synthesis of An(PDI) 2 which is composed of anthracene (An) as electron-rich core flanked with electron-deficient perylene diimide (PDI) to use in organic solar cells (OSCs) as an electron acceptor. The acceptor-donor-acceptor alternating structure afforded extended absorption range to 800 nm with suitable energy levels as an electron-acceptor. Despite An and PDI are highly conjugated molecules, An(PDI) 2 possesses slightly twisted architecture, which would limit severe aggregation of the molecules. For the purpose to optimize power conversion efficiency (PCE) of OSCs using An(PDI) 2 , the morphology of the photoactive blend film was tuned by solvent mixture system. Through the careful optimization, the solar cell device achieved PCE up to 5.42% with a V OC of 0.83 V, a J SC of 10.88 mA/cm 2 and FF of 0.60. This work suggests the potential of An(PDI) 2 as a promising non-fullerene acceptor molecule to be utilized in OSC applications. |
