Abstract:	摘要： Quantum dot-sensitized solar cells (QDSCs) constructed using cascade CdS/CdSe sensitizers and the novel tetrapod-like ZnO nanoparticles have been fabricated. The cascade co-sensitized QDSCs manifested good electron transfer dynamics and overall power conversion efficiency, compared to single CdS- or CdSe-sensitized cells. The preliminary CdS layer is not only energetically favorable to electron transfer but behaves as a passivation layer to diminish the formation of interfacial defects during CdSe synthesis. On the other hand, the anisotropic tetrapod-like ZnO nanoparticles, with a high electron diffusion coefficient, can afford a better carrier transport than traditional ZnO nanoparticles. The resultant solar cell yielded an excellent performance with a solar power conversion efficiency of 4.24% under simulated one sun (AM1.5G, 100 mW cm −2 ) illumination. A conversion efficiency as high as 4.24% has been achieved on CdS/CdSe quantum dot-sensitized solar cells consisting of novel tetrapod-like ZnO nanoparticles. 出版日期： 2012-09-19 資源來源： Royal Society of Chemistry 識別號： ISSN: 1463-9076 識別號： EISSN: 1463-9084 識別號： DOI: 10.1039/c2cp41760j
