Dye-sensitized solar cell

• A dye-sensitized solar cell (DSSC) is a low-cost solar cell belonging to the group of thin film solar cells.] It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system. A later version of a dye solar cell, also known as the Grätzel cell, was invented by Michael Grätzel.
• Because it could potentially be made of low-cost materials, if the use of noble materials like Platinum and Ruthenium is limited, 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. Although its conversion efficiency is less than the best thin-film cells, in theory its price/performance ratio (kWh/(m2·annum·dollar)) should be high enough to allow them to compete with fossil fuel electrical generation by achieving grid parity.
