Reusing silicon from end-of-life solar panels in EV batteries
Scientists in Belgium are exploring the potential of recycled silicon in solar modules at the end of their life cycle for reuse in low-cost, higher-energy-density storage technologies. They claim EV batteries using this silicon may allow faster recharging and travel longer distances on a single charge.
HHV builds directional solidification furnace for solar PV industry
Bengaluru-based Hind High Vacuum (HHV) has designed and built a directional solidification (DSS) furnace to produce polycrystalline silicon ingots in the solar industry.
Green hydrogen: A key enabler for a sustainable future
Green hydrogen holds the potential to decarbonize critical sectors and provide clean energy solutions. However, it accounts for less than 1% of global hydrogen production. Targeted interventions are required to facilitate a smooth transition toward a green hydrogen economy.
Photovoltaic-thermal solar panel based on water storage tank
A research group from Ireland developed a PVT system consisting of a 170 W photovoltaic panel connected to a water tank placed at the backside of the PV module itself. The PVT module is able to considerably reduce the temperature of the PV unit while producing hot water for residential use.
Bangladesh introduces fiscal breaks for solar-powered water desalination
Bangladesh has introduced tax exemptions to reduce water production costs and promote the use of solar power in 19 coastal districts. This initiative comes in response to grid electricity shortages caused by a decline in coal and fuel imports. The goal is to enhance reliance on solar-powered water desalination in these areas.
Saltwater redox flow battery with integrated ultracapacitor
US-based Salgenx says it has successfully integrated ultracapacitors with its saltwater redox flow batteries, resulting in significantly better power response and system performance.
Effect of wind on solar panel cooling in desert areas
Researchers in Morocco have carried out an experimental investigation which has confirmed that even in hot desert climates, the wind has a positive effect on reducing the PV module temperature, improving the electrical production as well as the conversion efficiency.
Improving ground-mounted solar power plant performance via orbiting reflectors
Scientists in the United Kingdom have proposed using orbiting solar reflectors to enhance the electricity yield of terrestrial solar power plants. They claim this new technology may be particularly beneficial for improving generation at dusk and dawn, when irradiance is lower.
Terrain-following solar tracker with a pneumatic twist
Sunfolding’s new TopoTrack rows are reportedly 10 times shorter than traditional trackers, and they can provide 20 degrees of variation between trackers, thus improving slope tolerance between rows.
