Dye-Sensitized Solar Cell Based on TiO2 Anode Thin Film with Three-Dimensional Web-like Structure

Abstract

TiO2 films with a three-dimensional web-like porous structure were prepared using the photo polymerization-induced phase separation method integrated with the pulling coating process. By adjusting the ratio of the substance in the precursor sol and the coating times, the relationships between the sol ratio, the coating times, the film structure, and the performance of the DSC were studied. The optimal film structure was found and a detailed description is given. The performance of the DSC was further improved by introducing the barrier layer and the surface-modified layer of the TiO2 coating. This promoted the short-circuit current density and the photoelectric conversion efficiency of the DSC, the mechanism of which was also investigated. Ultimately, the photoelectric conversion efficiency of the DSC based on the TiO2 anode films with a three-dimensional web-like structure was stabilized at a higher level as a result of the structural improvement.

Computational, Investigational Explorations on Structural, Electro-Optic Behavior of Pelargonidin Organic Colorant for TiO2 Based DSSCs

“…Among these, dye-sensitized solar cells (DSSCs) have a lower cost per watt production cost due to their ease of fabrication, relatively simple method and equipment compatible with mass production, and variety of applications such as wearable devices, indoor photovoltaic windows, and so on [5]. Photosensitizers are essential in DSSCs for capturing solar light photons and generating electric charges [6,7]. Harvesting electrical energy from solar energy will benefit the world to meet growing energy demand.…”
