| Summary: | 碩士 === 國立臺北科技大學 === 光電工程系研究所 === 96 === In this work, we develop ZnSe quantum-dots (QDs) dye-sensitized solar cells. The performance of solar cells was observed by changing the amount of ZnSe QDs. DSSCs with 5 wt% ZnSe QDs exhibited optimum results. The short-circuit current density Jsc = 4.83 mA/c , the open-circuit voltage Voc = 0.440, the fill factor FF = 0.301, and the power conversion efficiencies η = 0.64 %.
According to some reference adding golden nanoparticle layer between TiO2 and dyes can promote short-circute current density Jsc and reduce the open-circute voltage Voc. However in this experiment we try to mix gold nanoparticles and TiO2. Finally, =5.79 mA/c , Voc = 0.32 ，FF = 0.34 and η = 0.64 % are the result
