Uzbek government agrees to buy power from 200 MW solar plant
The solar park is being planned by UAE-based Phanes Group, in Nurata, in the Navoi region. It will sell electricity at a fixed rate over a 25-year period.
GoodWe launches two residential batteries
The Chinese manufacturer has unveiled a low-voltage battery with a modular design and a high-voltage storage system which is claimed to have a one-hour, ultra-rapid charge rate.
Cooling PV modules with radiative sky cooling
French scientists have proposed the use of radiative sky cooling as a passive cooling technique to cut PV module temperatures by 10 C. They claim the method could improve performance by more than 5 W/m2.
UNIST, EPFL claim 25.6% efficiency world record for perovskite solar cell
Scientists have set a new efficiency record for a single-junction perovskite solar cell at 25.6%. The cell additionally showed operational stability for 450 hours, and intense electroluminescence with external quantum efficiencies of more than 10%.
Australian manufacturer shares excess PV generation with staff
Hunter Douglas, a blinds and awnings manufacturer, will use the Enosi Powertracer platform to direct its oversupply of rooftop solar to its workforce.
India connects community energy storage to grid
Tata Power Delhi Distribution has installed a 150 kW/528 kWh battery energy storage system at a substation in New Delhi. The system will help the utility to manage peak load and frequency regulation, while providing 150 kW of power backup for durations of four hours.
Rooftop solar, storage and EVs in India
The combination of rooftop solar and storage is a big opportunity. A new report highlights Australia – a nation with the world’s highest per capita rooftop PV capacity – as a guide for Indian policymakers.
The Hydrogen Stream: Projects move forward in China, Japan, Australia and across several European countries
Sinopec wants to build 1,000 hydrogen refueling stations by 2025. Ways2H is building a facility in the Tokyo area that will convert daily 1 ton of dried sewage sludge into 40-50 kilograms of hydrogen for fuel cell mobility and power generation. Ørsted wants to deploy two renewable hydrogen production facilities for a total of 1 GW by 2030. Wacker Chemie is planning to produce green hydrogen and renewable methanol at its German site.
New design for antireflective coating in multijunction solar cells
Scientists in Madrid investigated the use of antireflective coatings in multijunction solar cells, drawing several conclusions that could further improve the efficiency of these cells. Their approach could improve on current antireflective coatings, particularly for high-efficiency multijunction cells, using methods and materials already proven in mass production.
Monograin layer solar cell with 6.4% efficiency
The lightweight and flexible cell was built by Estonian researchers with microcrystalline powders. The device is claimed to be the most efficient solar cell fabricated with a semiconductor compound known as Cu2CdGe(SxSe1−x)4.
