For a few decades, Many research of renewable energy were conducted. PSC(polymer solar cell) is one of them. It has various advantages including flexible and large area application. Herein, Diflourinated Phenazine (DFPz) is used as accepter unit in PSC. This unit was predicted that it has good charge mobility attributed to extended π conjugated structure. Phenazine was also expected that it has strong electronegativity attributed to C=N double bonds. And Benzodithiophene was used as donor unit in PSC. To investigate the effect of alkyl chain, ethyl hexyl, butyl octyl, decyl hexyl alkyl chain were introduced. In result, it was observe that the polymer with butyl octyl chain has better performance than the other polymers It’s because polymer with BO chain has proper alkyl chain for device performance. In summary, the polymer with BO chain (PBDT-DT-DFPz-BO) achieved 4.24% of PCE (power conversion efficiency). |
