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, ...

2,2',7,7'-Tetrakis(N,N-di-p-methoxyphenylamine)-9,9'-spirobifluorene (spiro-OMeTAD), the prevalent organic hole transport material used in solid-state dye-sensitized solar cells and perovskite-absorber solar cells, relies on an uncontrolled oxidative process to reach appreciable conductivity. This work presents the use of a dicationic salt of spiro-OMeTAD, named spiro(TFSI)2, as a facile means ...

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...

For the first time, nonstoichiometric WO2.72 was used as a counter electrode (CE) in dye-sensitized solar cells (DSSCs). Oxygen-vacancy-rich WO2.72 nanorod bundles with notable catalytic activity for triiodide and thiolate reduction were prepared in this study. The photovoltaic parameters of dye-sensitized solar cells (DSSCs) with WO2.72 nanorod bundles as CEs are superior compared with those o...

Nanocrystallite aggregates are spherical assemblies of nanometer-sized crystallites and feature a size on the order of sub-micrometers. This paper reports and summarizes recent progress in nanocrystallite aggregates for applications in dye-sensitized solar cells. It emphasizes that nanocrystallite aggregates are a promising class of materials with the capability to generate light scattering, en...

Dye-sensitized solar cells (DSSC) are known as 3rd generation cells. One of the most important parameters affecting performance DSSCs is thin film thickness that forms photoanode layer. In this study, we examined how 38, 60 and 76 µm thick TiO2 films change dye-sensitized cell performance. The highest efficiency (4.73%) was seen in with 38 thickness. addition, mineralogical morphological analys...
