Dye-Sensitized Solar Cell (DSSC) with Improved Solar Cell Efficiency

• SCIENTISTS from IIT Hyderabad along with other researchers  have developed a solar cell based on inexpensive New  Fuchsin (NF) dye with aqueous electrolyte and platinum-free counter electrodes.
• Conventionally, solar cells are made of silicon which is quite expensive and fabrication is also costly. New Fuchsin dye is traditionally used to produce kumkum or vermillion. DSSC is cheap, non-toxic, insoluble in water as well as eco-friendly and contains three components monolayers of dye molecules adsorbed on semiconductor material, Titanium Dioxide (TiO2) deposited on transparent conductive oxides, and a liquid electrolyte with a surplus of electrons. DSSC is a third-generation thin-film molecular conversion device which mimics the process of photosynthesis. It can serve as a solution to the drawbacks faced by conventional silicon-based solar cells. The study has been published in the journal Solar Energy.
