dc.description.abstract | ADA conjugated polymer, PTPD-TVT, containing thienopyrroledione and thiophenevinylenethiophene (TVT) units was synthesized as an electron donor for organic photovoltaic devices. It possesses a small bandgap and has excellent coplanarity and high hole mobility. To further enhance the interchain interactions between the polymer chains, a selenophenevinyleneselenophene (SVS) unit was also introduced and copolymerized to form the PTPD-SVS polymer. Devices made from PTPD-TVT and PTPD-SVS have rather promising power conversion efficiencies (PCEs) of 4.87 and 5.74%, respectively. The higher PCE value for solar cells based on PTPD-SVS was attributed to an enhanced carrier mobility resulting from stronger interchain aggregation in the BHJ active layer. These results show that the incorporation of a vinylene unit in TPD-based polymers is an effective way to reduce the bandgap and thereby improve charge transport for efficient photovoltaic devices. | - |
