A German-Israeli research group has gathered for three days to discuss which storage technologies may outperform lithium-ion batteries in the future. They concluded that there is no such a thing as a “post Li‐ion” era in sight. They recommended a “side‐by‐side” approach for multiple technologies in different applications, as well as the hybridization of technologies. The group highlighted the strong potential of redox flow storage, which in their view may outperform Li‐ion, although only for stationary applications.

The projects shall be co-funded by India’s Department of Science & Technology and the European Commission’s Innovation and Networks Executive Agency. The aim is to make energy supply cleaner, more efficient and affordable by smartly integrating large amounts of renewable energy in local energy systems. Proposals can be submitted till September 1.

Scientists in the U.S. and Nigeria have studied the effects of pressure on perovskite solar cell production and found the correct application could improve cell efficiency by as much as 40% (relative). Push them too hard though, and they crack.

The market for drones in the power and utility industry will grow 23.6% annually, reaching $515 million by 2030—according to a Frost & Sullivan report.
The report, Drones in the Global Power and Utilities Industry, Forecast to 2030, cites ongoing digital transformation, remote monitoring, and the need to optimize operational costs as the factors driving increasing adoption of drones in the power and utility industry.
“Drones minimize the need to send human employees onsite and can be deployed for monitoring, operations, and maintenance services. As the global power and utility industry continues to tackle the impact of the ongoing Covid-19 pandemic, drones can be potential game-changers in combating the challenges it poses,” as per the report.
pv magazine spoke to Supreeth Srinivasa Rao, Associate Director, Industrial Practice, Frost & Sullivan, to find out the role of drones in the solar sector, especially for India.

Scientists in Egypt have investigated the effectiveness of using water and a mixture of aluminum oxide and calcium chloride hexahydrate to cool PV modules. Optimal performance was observed with a solution of 75% water, according to the research findings.

U.S. researchers have created an inorganic mixed halide perovskite solar cell which they claim shows no thermal degradation even at 200 degrees Celsius for three days. The device can be used in tandem junction cells and is designed for use in real-life environments with high solar irradiation.

Analysts at Bloomberg New Energy Finance say the lowest-cost projects financed in Australia, China, Chile and the UAE in the last six months hit a levelized cost of energy of just $23-29/MWh and the best solar and wind projects will produce electricity for less than $20/MWh by 2030.

Trina Solar’s new Vertex series of bifacial modules have a conversion efficiency of up to 21% and can deliver more than 500W of power from the front surface.

Developers have until June 30 to lodge bids to develop plots of solar capacity across the national rail network paying no more than Rs2.71/kWh for the electricity generated under a 25-year contract.

The state-owned Central Electronics Limited seeks to empanel startups having the technology patent for waterless solar module cleaning system without any moving parts as its intends to manufacture such systems at its facilities.
