Article Synopsis
- - Researchers developed a simpler method to fabricate TiO2 layers for dye-sensitized solar cells (DSSCs) by using a nano-particle deposition system (NPDS), eliminating the complex steps of traditional paste-based methods.
- - This new method involves spraying nanocrystalline TiO2 powders of varying sizes directly onto transparent conductive oxide (TCO) glass, which enhances the layer's porosity and light scattering properties.
- - The study found that DSSCs created with a mix of different particle sizes performed better than those using a single particle size, indicating that the NPDS method improves solar cell efficiency and is adaptable to flexible substrates at room temperature.
TiO2 powders were deposited on indium tin oxide (ITO) coated polyethylene terephthalate (PET) substrates for application to the photoelectrode of a dye-sensitized solar cell (DSSC). In the conventional DSSC manufacturing process, a semiconductor oxide such as TiO2 powder requires a sintering process at higher temperature than the glass transition temperature (T(g)) of polymers, and thus utilization of flexible polymer substrates in DSSC research has been constrained. To overcome this restriction related to sintering, we used a nanoparticle deposition system (NPDS) that could produce a thin coating layer through a dry-spray method under atmospheric pressure at room temperature.
