We synthesized D-A conjugated polymer for the application in organic photovaoltaic cells. In polymer, Benzodithiophene(BDT) unit was used as the electron donor and benzothiadizole (BT) and quinoxaline (Qx) were used as the withdrawing unit. To know the photovaoltaic performance, PCBM was used as donor unit and these polymers were used as acceptor unit in photovaoltaic cells. We have different results accroidng to differernt main units in electron withdrawing parts in polymer. We selected Cyano group as an electron-withdrawing moiety to enhacne Voc and Jsc. To figure out the poylmer, some of the measurement were executed such as Differential Scanning Calorimetry (GPC), Thermal Gavimetric Analysis, Cyclic voltamnetry, and Uv visble and so on. To know the photovaoltaic performance. |
