A New Benzodithiophene Based Donor-Acceptor π-Conjugated Polymer for Organic Photovoltaics |
| 초록 |
A new π-conjugated donor-acceptor polymer (PB-1) is synthesized with the side chain engineering on benzodithiophene (BDT) and studied as donor for organic photovoltaics (OPV). The thermal, electrochemical and optical properties of PB-1 were studied systematically. Introduction of hexyl benzene side chain on BDT core exhibited good absorption profile ranging from 300-750 nm with Egopt = 1.85 eV, and showed better solubility in halogenated and non-halogenated solvents. Therefore, organic solar cell(OSC)s were fabricated with PB-1 as donor and IT-4F as acceptor. The device displayed a power conversion efficiency (PCE) of 4.02%. The PB-1 showed comparatively high fill factor and short circuit current density when fabricated along with Y6 compared to IT-4F as acceptor. The PCE showed improvement by 5.01% when fabricated PB-1 with Y6 acceptor. |
