Novel nanowire array based highly efficient quantum dot sensitized solar cell.
In this communication, a novel CdSe/CdS/ZnO nanowire array fabricated by a 3-step solution-based method was used as a photoanode of a quantum dot sensitized solar cell, which generated a maximum power conversion efficiency of 4.15%.
متن کاملHighly efficient quantum dot-sensitized TiO2 solar cells based on multilayered semiconductors (ZnSe/CdS/CdSe).
A new approach by inserting a layer of ZnSe QDs was studied to enhance the adsorption of CdS/CdSe QDs resulting in much improved power conversion efficiency. ZnSe, CdS and CdSe QDs were sequentially assembled on a nanocrystalline TiO2 film to prepare a ZnSe/CdS/CdSe sensitized photoelectrode for QD-sensitized solar cell (QDSSC) applications. The results show that the performance of QDSSCs is st...
متن کاملZnO nanoparticle based highly efficient CdS/CdSe quantum dot-sensitized solar cells.
20 nm ZnO nanoparticles are used to fabricate the mesoporous photoanode of the CdS/CdSe quantum dot-sensitized solar cells by the simple doctor blade method. A maximum power conversion efficiency of 4.46% has been achieved, which indicated exciting prospects for ZnO nanoparticle based quantum dot-sensitized solar cells.
متن کاملSILAR Sensitization as an Effective Method for Making Efficient Quantum Dot Sensitized Solar Cells
CdSe quantum dots were in situ deposited on various structures of TiO2 photoanode by successive ionic layer adsorption and reaction (SILAR). Various sensitized TiO2 structures were integrated as a photoanode in order to make quantum dot sensitized solar cells. High power conversion efficiency was obtained; 2.89 % (Voc=524 mV, Jsc=9.78 mA/cm2, FF=0.56) for the cells that sensitized by SILAR meth...
متن کاملQuantum Dot Sensitized Solar Cells
In response to rapidly increasing global energy demand, the development of alternative energy sources to fossil fuels has emerged as one of the most urgent technological challenges. Solar energy, which represents a nearly unlimited source of clean power, has been considered as one of the most promising new energy sources. In addition to the current success of silicon based solar cells, quantum ...
