چکیده

A quantum dot sensitized solar cell based on a porous ZrO(2) film, sensitized with CdSe quantum dots using CdS as an intermediate layer is presented. We observe electron injection from photo-excited quantum dots into the ZrO(2), which is unexpected due to the much higher conduction band edge (closer to the vacuum level) of bulk ZrO(2) compared to TiO(2).

SILAR 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...

High-efficiency cascade CdS/CdSe quantum dot-sensitized solar cells based on hierarchical tetrapod-like ZnO nanoparticles.

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...

Preparation of CdIn2S4-CdS nanocomposite via a green route and using them in dot-sensitized solar cells for boosting efficiency

In this work In2S3 and CdS nanoparticles were prepared by a simple hydrothermal method and then annealed at 500 °C for 2 h in an Ar gas until CdIn2S4(CdIS)-CdS nanocomposites were formed. Afterwards, efficiency of the as-synthesized CdIS-CdS nanocomposite in quantum dot-sensitized solar cells (QDSSCs) was evaluated. For this purpose, the as-prepared CdIS-CdS nanocomposites were deposited on TiO...

Highly 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...

CdS/CdSe Co-Sensitized Solar Cell Prepared by Jointly Using Successive Ion Layer Absorption and Reaction Method and Chemical Bath Deposition Process

CdS/CdSe quantum dots co-sensitized TiO2 solar cell was prepared by combining the successive ion layer absorption and reaction (SILAR) method and chemical bath deposition (CBD) method for the fabrication of CdS and CdSe quantum dots, respectively. The effect of CdSe deposition time on the solar cell performance was investigated. It was found that the optimized deposition time for CdSe was 3 h, ...
