碩士 === 國立臺灣大學 === 應用物理所 === 99 === A new flexible organic/inorganic hybrid photovoltaic (HPV) device has been demonstrated. The layered structure of the HPV consists of polyethylene terephthalate (PET)/ Graphene /ZnO nanorods/ poly(3-hexylthiophene):phenyl-C61-butyric acid methyl ester (P3HT:PCBM)/Ag. It is found that the power conversion efficiency and the short-circuit current density of the device can be enhanced with increasing bending angles. The highest enhancement of power conversion efficiency can reach up to 30% compared with flat counterpart. While the device returns to the original condition, the power conversion efficiency will recover to its initial value. These interesting phenomena can be attributed to the light trapping effect in ZnO nanorods and the outstanding capability of graphene.
