| Abstract: |
| 【Objective】To improve the traditional inorganic solar cells,a novel copolymer was synthesized and developed.【Method】The copolymers of P(iI-EDOT) derived from EDOT and isoindigo were obtained through the palladium-catalyzed Suzuki coupling method.The properties were characterized through a variety of instruments,including thermo gravimetric analysis,UV-vis absorption spectra and Current Voltage measurement.The organic solar cells using traditional architecture were fabricated to investigate the potential photovoltaic performance.【Result】The novel polymer had good thermal stability,reasonable highest occupied molecular orbital energy levels (EHOMO) and lowest unoccupied molecular orbital energy levels (ELUMO).The photovoltaic performance test of organic solar cells based on P(iI EDOT) showed the maximum short-circuit current density (Jsc) of 2.80 mA/cm2,an open circuit voltage (Voc) of 0.45 V,and a fill factor (FF) of 28% with the resulting average power conversion efficiency (PCE) of 0.35%.【Conclusion】Follow-up studies are needed to improve the energy conversion efficiency of the novel copolymer. |
