DYE-SENSITIZED SOLAR PANEL
A dye-sensitized solar cell is a low-cost solar cell belonging to the group of thin film solar cells. DSSCs are currently the most efficient third-generation solar technology available. Other thin-film technologies are typically between 5% and 13%, and traditional low-cost commercial silicon panels operate between 14% and 17%. 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.
The major disadvantage to the DSSC design is the use of the liquid electrolyte, which has temperature stability problems. At low temperatures the electrolyte can freeze, ending power production and potentially leading to physical damage. Higher temperatures cause the liquid to expand, making sealing the panels a serious problem. Another disadvantage is that costly ruthenium dye, platinum catalyst and conducting glass or plastic contact are needed to produce a DSSC. A third major drawback is that the electrolyte solution contains volatile organic compounds , solvents which must be carefully sealed as they are hazardous to human health and the environment.
Dye sensitized solar panels are low-cost solar panels belonging to the group of thin film solar panels.It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system.Dye sensitized solar panels have a number of attractive features; they are simple to make using conventional roll-printing techniques, are semi-flexible and semi-transparent which offers a variety of uses not applicable to glass-based systems, and most of the materials used are low-cost. Due to this dye sensitized solar panels are one of the cheapest in solar panel industry. But In practice they have proven difficult to eliminate a number of expensive materials, notably platinum and ruthenium, and the liquid electrolyte presents a serious challenge to making a cell suitable for use in all weather.Commercial applications, which were held up due to chemical stability problems.

The liquid electrolyte presents a serious challenge to making a panel suitable for use in all weather. Overall peak power conversion efficiency for current DSSCs is about 11% and for solar panel it ranges around 8%. DSSCs degrade when exposed to ultraviolet radiation which is highest losses compare to other losses such like oxidation losses of solar panel and due to this lifespan of dye sensitized solar panel considerable low and ranges around 6 years. Due to very low cost solar industry looking as bright option for future.
