Air pollutants reduce India’s solar power generation by 17%

In India, particulate matter deposited on solar panels and present in the ambient air is responsible for about 17% reduction in solar power generation. This translates to about 2 GW reduction in solar power production for about 12 GW installed solar power capacity in the country. India has set an ambitious renewable energy target of 175 GW by 2022. Particulate matter … Continue reading Air pollutants reduce India’s solar power generation by 17%

IIT Bombay team finds Chennai and Mumbai have high wind energy potential

Of the six cities studied by Indian Institute of Technology (IIT) Bombay researchers, Chennai and Mumbai seem to have the highest potential to harvest wind energy during the active phase of the monsoon period. Compared with these two cities, Indore, Ahmedabad and Kolkata have less potential; Delhi has the least potential. The results were published … Continue reading IIT Bombay team finds Chennai and Mumbai have high wind energy potential

Voila! NPL scientists produce electricity from water without using electrolyte, light

In a major breakthrough, scientists at Delhi’s National Physical Laboratory (NPL) have developed a novel way of producing electricity from water at room temperature without supplying any external energy or using electrolyte or light. A team led by Dr. R.K. Kotnala used nanoporous magnesium ferrite to split water into hydronium (H3O) and hydroxide (OH) ions … Continue reading Voila! NPL scientists produce electricity from water without using electrolyte, light

Electric bicycles from Chennai to hit the road soon

The Chennai-based Basil Energetics is ready to launch an electric bicycle, iZip, in Hyderabad by the end of this month. Fitted with a long-lasting and light-weight portable lithium iron phosphate battery (like the ones used in Tesla and Toyota), iZip can travel at a top speed of 20 km per hour. The cycle, which weighs … Continue reading Electric bicycles from Chennai to hit the road soon

IISc’s self-powered UV photodetector can power electronic devices

In a novel approach, researchers from the Indian Institute of Science (IISc), Bangalore, have developed a cost-effective, high-performance, self-powered UV photodetector that can use the harvested optical energy for direct self-charging of energy storage devices such as supercapacitor. It can also be used for operating electronic devices in the absence of external power source. The … Continue reading IISc’s self-powered UV photodetector can power electronic devices

IISER Kolkata uses human hair to produce cheaper cathodes for solar cells

Researchers at the Indian Institute of Science Education and Research (IISER) Kolkata have used human hair to produce cost-effective, metal-free cathodes for use in solar cells. This is the first instance where a bio-waste-derived electrode has been used as a cathode in a quantum dot sensitised solar cell device. While metal-free cathodes produced in the … Continue reading IISER Kolkata uses human hair to produce cheaper cathodes for solar cells
