Energy harvesting Current Affairs, GK & News
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 ..

Piezoelectric effect used by US researchers to develop a wearable device that could generate energy from swing of an arm while walking or jogging
The US researchers have developed a wearable device that could generate energy from the swing of an arm while walking or jogging. The device, about the size of a wristwatch, produces enough power to run a personal health monitoring system. The prototype watch is apparently made from a crystal material, which can produce an electric ..
Suntech Power, the Chinese solar power manufacturer developed a new process for manufacturing silicon wafers for solar cells that could slash the cost of solar power by 10 to 20 %. It uses wafers made up of a single crystal of silicon. These are called “monocrystalline” wafers.
