German researchers claim to have reduced ribbing effects in using slot-die coating for the production of perovskite solar cells. The results are reportedly the most efficient solar cell built with this technique to date.

Australian battery manufacturer Redflow has signed a deal that will see it supply its “non-lithium” energy storage technology to clean energy outfit Ameresco which is looking to develop integrated solar and zinc-bromine flow battery solutions for its customer base throughout North America and Europe.

While it initially had a chilling effect on the Polish residential solar market, the transition from net metering to net billing has also resulted in positive changes, such as better sizing of rooftop PV systems and a higher rate of self-consumption, says Instytut Energetyki Odnawialnej (IEO), a Polish research body.

iDM has developed a modular air-source heat pump that uses propane (R290) as the refrigerant. It can produce between 2 kW and 24 kW of heat and domestic hot water up to a temperature of 70 C. A larger version can produce between 10 kW and 50 kW of heat.

The minigrid space continues to attract a lot of attention from development partners in Africa. Minigrids can actually generate profits, so there is no doubt that commercial finance players will eventually jump on the bandwagon, according to the Africa Solar Industry Association (AFSIA).

The International Renewable Energy Agency (IRENA) explains how to optimally use its SolarCity Simulator, an open-access platform designed to help member countries to deploy PV systems at the municipal level.

Arizona-based Solestial’s silicon-based solar cells exhibit a high level of resilience in space, according to third-party testing.

China Southern Power Grid, a state-owned utility, has revealed plans to use alloy materials to store hydrogen.

Zhang Yingbin, Trina Solar’s head of global product strategy, speaks to pv magazine about the path to a supply chain dominated by n-type TOPCon products. He says Trina Solar will reach 30 GW of TOPCon solar module capacity by the end of 2023.

C2F has developed a building-integrated PV (BIPV) facade made of aluminum that purportedly limits the impact of hot and cold weather, while also improving solar module performance.
