DSSCs separate the light absorption and charge transfer processes, unlike Si-based cells.The organic dyes, or sensitizer molecules, adsorbed on the surface of the metal oxide nanostructure take the role of absorbing the incoming light, and the rest of the structure transfers the generated charge.This paper summarizes the recent progress in DSSC technology for improving efficiency, focusing on the active layer in the photoanode, with a part of the DSSC consisting of dyes and a Ti OFor nearly two centuries, mankind has employed fossil fuels as the primary energy source, and now we are facing serious problems as a result.

Dye-sensitized solar cells (DSSCs) have been widely studied due to several advantages, such as low cost-to-performance ratio, low cost of fabrication, functionality at wide angles and low intensities of incident light, mechanical robustness, and low weight.

In order to mitigate the severe performance deterioration in larger size DSSC solar cells, the use of anodized Ti O₂ nanotubes was introduced on Ti foil.

Instead of FTO glass, the photoanode was made of Ti foil.

However, there are some problems, such as complicated and difficult fabrication processing and high cost [6].

Dye-sensitized solar cells (DSSCs) are one potential alternative to silicon solar cells.A significant improvement in the performance in the DSSC was obtained from the DWCNTs-Ti O₂ photoanode.Comparing to the standard Ti O₂ anode, the carbon nanotube-containing Ti O₂ anode with 0.2 wt.% DWCNTs has boosted up the photocurrent density (Jsc) by 43%.DSSCs provide several advantages, such as low price-to-performance ratio, low processing cost, ability to work at wide angles and low intensities of incident light, mechanical robustness, light weight, and aesthetically appealing transparent design.DSSCs have a number of remarkable properties that allow them to be used for several niche applications; they are low in weight and able to display various colors and transparency, and they work effectively in a broad range of wavelengths [8, 9].The thesis focuses on the development of economically competitive photoelectrodes with the motivation to further enhance energy conversion efficiency of DSSCs.Practical and scalable device fabrication is also proposed and studied in details.Dye sensitized solar cells (DSSCs) represent a cheap and clean technology to harnesses solar energy efficiently.To further decrease the production cost while improving the device performance is a bottleneck for large scale application and commercialization of DSSCs.The best power conversion efficiency of 5.38% was obtained on micropaper with a combination of Ti O₂ nanospherical particles and a 1D nanostructure.Incorporation of double- walled carbon nanotubes (DWCNTs) into a Ti O₂ photo-anode layer has been studied.
