Efficient conjugated polymer-ZnSe and -PbSe nanocrystals hybrid photovoltaic cells through full solar spectrum utilization
چکیده انگلیسی

Type-II heterojunction poly[(2-methoxy,5-octoxy)-1,4-phenylenevinylene] (MOPPV)–ZnSe nanocomposites synthesized by in situ polymerization method are studied with and without incorporation of PbSe quantum dots (QDs) active layer in the novel hybrid photovoltaic device architecture for full solar spectrum utilization. The performance of the device improves significantly by incorporated PbSe QDs active layer. The power conversion efficiency, open-circuit voltage, short-circuit density and fill factor of the device with PbSe QDs are 0.14%, 0.806 V, 0.309 mA and 34%, respectively. It is expected that PbSe QDs active layer provides wider interface and surface areas for efficient exciton dissociation and charge transport, as well as more photon capture and exciton generation by absorption in near infrared spectrum region.
