The researchers at IIT Hyderabad develop eco-friendly solar cells using kumkum dye
The scientists at IIT Hyderabad have developed low-cost, environment-friendly solar cells by employing an off-the-shelf dye used to make kumkum or vermilion in India. The Dye-Sensitised Solar Cell (DSSC) is based on New Fuchsin (NF) dye with aqueous electrolyte and platinum-free counter electrodes. The research is published in the Solar Energy journal. The most familiar ..
