More efficient large-area organic solar cells with spin coating

Researchers in South Korea have used the process to increase performance and the replicability of large-area organic cells. The method was used during film formation to speed up solvent evaporation.

Vanadium redox flow battery for storage of wind and solar power

Researchers in India have developed a 5 kW/25 kWh vanadium redox flow battery with an energy density of 30 watt-hours to 40 watt-hours per liter.

How long will the lithium supply last?

Researchers have sounded the alarm. If no serious efforts are made on second-life battery use, recycling and vehicle-to-grid applications, decarbonization efforts may hit the buffers a lot sooner than expected.

NREL scientists estimate global potential of hydro-linked floating PV at up to 7.5 TW

The U.S. based researchers said linking solar with hydro in a full hybrid system configuration may result – at best – in the deployment of 7,593 GW for an estimated annual power generation of 10,616 TWh and a 20% reservoir coverage. And combining solar with hydro in this way brings further benefits, including improved system operation at different time scales, more opportunities for storage thanks to pumped hydro, increased utilization rates of transmission lines, reduced PV curtailment, and lower interconnection costs and water evaporation.

CSIR-CMERI Durgapur, NISE sign pact on solar research and capacity building

The CSIR-Central Mechanical Engineering Research Institute (CMERI), Durgapur, which has expertise in the design and development of solar artifacts for multifaceted uses, and the National Institute of Solar Energy (NISE), Gurugram, will conduct joint field studies for different solar technologies and work towards skill and capacity building.

Machine-learning for PV module cleaning

French researchers have developed a machine-learning model to clean low-power PV projects and standalone solar arrays in rural areas isolated from the grid.

Over 26,000 register for World Solar Technology Summit tomorrow

The Summit will see the signing of four partnership agreements, including one between India’s Ministry of New and Renewable Energy, World Bank, and International Solar Alliance.

A solar cell so thin, it can rest on a soap bubble

Scientists at Saudia Arabia’s King Abdullah University of Science and Technology demonstrated an organic PV cell that can simply be printed onto a piece of paper. The cell set a new efficiency record for a fully inkjet-printed device, and its designers envisage applications in integrated medical sensors.

C-MET seeks co-funding partner for lithium and sodium-ion battery cell manufacturing

The selected party will provide funding support of Rs 4 crore by way of design and development of machinery for lithium- and sodium-ion battery cell manufacturing. September 30 is the deadline to submit the interest.  

Solar-powered hydrogen under $2/kg by 2030

Researchers from the Massachusetts Institute of Technology have identified sites where hydrogen could be produced via PV electrolysis at prices ranging from $1.90/kg to $4.20/kg in the United States by the end of the decade.
