IIT Hyderabad develops low-cost, eco-friendly solar cells using ‘kumkum dye’

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, according to the research published in the Solar Energy journal. The most familiar […]

IIT Hyderabad improves solar cell efficiency using magnetic field

Researchers at IIT Hyderabad have developed a novel process to improve the performance of third generation solar cells using magnetic field. Working with dye sensitised solar cells (DSSC), they have shown that the incorporation of magnetic nanoparticles (Fe3O4) in the anode can enhance light-to-power conversion efficiencies.  Anode is the positively charged electrode by which the electrons leave an electrical device.  There is much promise […]

Perovskite solar cell: interface makes the difference

Perovskite-based solar cells are the fastest-advancing solar technology to date. Since they were first used in 2009, perovskite solar cells have achieved high efficiencies (over 22% under standard solar irradiation) at low production costs. Although most of the perovskite components are optimized, there’s still room for improvement. Especially in reference to the Hole Transport Materials […]

Do solar panels and home batteries save energy?

The energy produced over the lifetime of typical rooftop solar panels more than makes up for the energy it takes to make, mount and then eventually recycle them. But adding a home battery usually lowers those dividends, according to new research from Stanford University. Previous studies estimated the energy output to be about nine times […]
