Singapore’s Sembcorp plans to install several solar plants near 1.4 GW of coal power capacity that developers are now building in Bangladesh.

The Australian state of Queensland’s push to source 70% of its energy supplies from renewables by 2032 has received a boost with the completion of the 162 MW Columboola Solar Farm.

The 2022 Solar Generation Index report shows that solar asset performance is falling below estimates.

Canadian researchers have developed a new model to improve the performance of building-integrated PV (BIPV) shades in buildings. They considered solar electricity, heat transferred through windows, and interior daylighting quality.

Danish researchers have built a selenium solar cell with the highest open-circuit voltage ever reported. They said that with further improvements in the optoelectronic quality of selenium, the device could reach an efficiency of up to 8%.

Researchers in the Netherlands have designed a water-splitting system with an electrochemical cell and a 25%-efficient tandem perovskite-silicon solar cell. It can reportedly achieve a solar-to-hydrogen efficiency rating of more than 21%.

The International Energy Agency says that it expects the use of renewables to support global hydrogen production to surge over the next five years. The Netherlands and Denmark, meanwhile, have revealed plans to expand electrolysis capacity.

Acciona Energia is setting up its first V2G network in Spain, ADS-TEC has unveiled a battery-based, all-in-one system with up to 300 kW of charging power, and Volkswagen is looking for a location for its first battery cell factory in North America.

A UK research group has proposed the combination of solar-powered heat pumps and thermal storage based on phase-change materials for residential applications. They said such a system could facilitate cost savings of up to 39%.

Linyang Energy has revealed plans to build a new solar factory in Jiangsu province, while Daqo has said it will build a new silicon production base in Inner Mongolia.

Enphase CEO Badri Kothandaraman has said that the company will build four to six new manufacturing lines in the United States.
