摘要： Photocatalytic materials based on coupling of semiconductor nanocrystalline quantum dots (NQD) and molecular catalysts. These materials have capability to drive or catalyze non-spontaneous chemical reactions in the presence of visible radiation, ultraviolet radiation, or both. The NQD functions in these materials as a light absorber and charge generator. Following light absorption, the NQD activates a molecular catalyst adsorbed on the surface of the NQD via transfer of one or more charges (either electrons or electron-holes) from the NQD to the molecular catalyst. The activated molecular catalyst can then drive a chemical reaction. A photoelectrolytic device that includes such photocatalytic materials is also described.

摘要： Semiconductor nanocrystals (NCs) are promising materials for applications in photovoltaic (PV) structures that could benefit from size-controlled tunability of absorption spectra, the ease of realization of various tandem architectures, and perhaps, increased conversion efficiency in the ultraviolet through carrier multiplication. The first practical step toward utilization of the unique properties of NCs in PV technologies could be through their integration into traditional silicon-based solar cells. Here, we demonstrate an example of such hybrid PV structures that combine colloidal NCs with amorphous silicon. In these structures, NCs and silicon are electronically coupled, and the regime of this coupling can be tuned by altering the alignment of NC states with regard to silicon band edges. For example, using wide-gap CdSe NCs we demonstrate a photoresponse which is exclusively due to the NCs. On the other hand, in devices comprising narrow-gap PbS NCs, both the NCs and silicon contribute to photocurrent, which results in PV response extending from the visible to the near-infrared. This work demonstrates the feasibility of hybrid PV devices that combine advantages of mature silicon fabrication technologies with the unique electronic properties of semiconductor NCs.

摘要： Photoelectrochemical solar cells (PECs) consisting of a photoanode were prepared by direct deposition of independently synthesized CdSe nanocrystal quantum dots (NQDs) onto a nanocrystalline TiO2 film (NQD/TiO2), aqueous Na2S or Li2S electrolyte and a Pt counter electrode. The light harvesting efficiency (LHE) of the NQD/TiO2 photoanode is significantly enhanced when the NQD surface passivation is changed from tri-n-octylphosphine oxide (TOPO) to a smaller ligand (e.g. n-butylamine (BA)). Using NQDs with a shorter passivating ligand, BA, leads to a significant enhancement in both the electron injection efficiency at the NQD/TiO2 interface and charge collection efficiency at the NQD/electrolyte interface, with the latter attributed mostly to a more efficient diffusion of the electrolyte through the pores of the photoanode. By utilizing BA capped NQDs and aqueous Li2S as an electrolyte, it is possible to achieve about 100% internal quantum efficiency of photon-to-electron conversion, matching the performance of dye sensitized solar cells.
摘要翻译：通过将独立合成的CdSe纳米晶体量子点（NQD）直接沉积到纳米晶体TiO 2膜（NQD / TiO 2），Na 2 S或Li 2 S水溶液和Pt对电极上来制备由光电阳极组成的光电化学太阳能电池（PEC）。当NQD表面钝化从三正辛基氧化膦（TOPO）改变为较小配体（例如正丁胺（BA））时，NQD / TiO2光阳极的光收获效率（LHE）显着提高。使用具有更短钝化配体的NQD，BA导致在NQD / TiO 2界面处的电子注入效率和NQD /电解质界面处的电荷收集效率的显着增强，后者主要归因于更有效的扩散电解质通过光阳极的孔。通过使用BA封端的NQD和Li2S水溶液作为电解质，可以实现大约100％的光子到电子转换的内部量子效率，匹配染料敏化太阳能电池的性能。
