Homemade dye-sensitized solar cells were used to investigate ways to prolong the operational lifespan of the cells and increase their current production rates.

Benzoic acid was used to inhibit bacterial growth on the natural plant dye, and sealing agents were used to prevent the evaporation of liquid electrolyte. It was investigated if the cells containing a mixture of pigments would produce higher current readings than the control cells due to an increased absorption spectrum.

The optimal pH levels for several dye pigments were determined. It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte; a photoelectrochemical system.

Because it is made of low-cost materials and does not require elaborate apparatus to manufacture, this cell is technically attractive.

Likewise, manufacture can be significantly less expensive than older solid-state cell designs. It can also be engineered into flexible sheets and is mechanically robust, requiring no protection from minor events like hail or tree strikes.

Commercial applications, which were held up due to chemical stability problems, are now forecast in the European Union Photovoltaic Roadmap to significantly contribute to renewable electricity generation by The titanium dioxide is immersed under an electrolyte solution, above which is a platinum-based catalyst.

As in a conventional alkaline battery, an anode the titanium dioxide and a cathode the platinum are placed on either side of a liquid conductor the electrolyte.

Sunlight passes through the transparent electrode into the dye layer where it can excite electrons that then flow into the titanium dioxide. The electrons flow toward the transparent electrode where they are collected for powering a load.

Dye-Sensitized Solar Cells (DSSCs) - Science Fair Project

After flowing through the external circuit, they are re-introduced into the cell on a metal electrode on the back, flowing into the electrolyte.

The electrolyte then transports the electrons back to the dye molecules. Thus the electrical circuit loop is closed. DSSCs are currently the most efficient third-generation solar technology available.

This makes DSSCs attractive as a replacement for existing technologies in "low density" applications like rooftop solar collectors, where the mechanical robustness and light weight of the glass-less collector is a major advantage.

They may not be as attractive for large-scale deployments where higher-cost higher-efficiency cells are more viable, but even small increases in the DSSC conversion efficiency might make them suitable for some of these roles as well.Brian was created as Brian Joseph Regan in Miami, Florida, United states.
