Scientists claim PV systems combined with thermoelectric cooling may achieve 6-year payback time
Scientists in South Africa have modeled a photovoltaic system connected to a thermoelectric cooling device and have found it may produce around 9.2% more electricity than conventional PV system without cooling. The research team claims the proposed system guarantees a minimum cost saving of 10.56%.
The Hydrogen Stream: GAIL opens 10 MW green hydrogen plant
GAIL (India) Ltd, India’s largest natural gas company, has set up a green hydrogen plant that can produce 4.3 tonnes of hydrogen per day through 10 MW PEM (proton exchange membrane) electrolyzer units.
Solar panels in orbit
Space-based solar power generation has the potential to address many of the challenges that terrestrial systems face.
Fraunhofer ISE unveils M10 TOPCon solar cell with 24.0% efficiency
The German research institute said the new 120 µm thin solar cell could exceed 25% efficiency with the next optimization steps. The device was metalized via screen-printed contact fingers and calibrated by scientists at the Institute for Solar Energy Research Hamelin.
China’s Renshine plans GW-scale perovskite PV panel factory
Renshine Solar says it will open a gigawatt-scale perovskite PV module factory in Jiangsu province, with a planned investment of CNY 1 billion ($138 million). In January, it reported that its perovskite solar panels had achieved a power conversion efficiency of 18.4%.
U.S. scientists develop air-bridge thermophotovoltaic cells with 44% efficiency
U.S. scientists have developed a thermophotovoltaic cell that could be paired with inexpensive thermal storage to provide power on demand. The indium gallium arsenide (InGaAs) thermophotovoltaic cell absorbs most of the in-band radiation to generate electricity, while serving as a nearly perfect mirror.
Solarwatt shuts down battery factory in Germany
Solarwatt says it will shut down its battery factory in Germany. Battery production at the Dresden facility will halt at the end of this year, and the company will move all battery and solar panel production to China.
Lead-free inverted perovskite solar cells without transparent conducting oxides may achieve 30% efficiency
Researchers in Nigeria have proposed to build inverted perovskite solar cells exclusively with all-inorganic transport materials and a lead-free perovksite absorber. Through a series of simulations, they showed these device may achieve efficiencies over 30% with low production costs.
Bladeless wind energy innovation aims to compete with rooftop solar
A compact, “motionless” wind turbine with a magnetic generator designed for large commercial rooftops provides 5 kW of capacity per unit. Aeromine Technologies secured Series A funding for scaling its innovative design.
Renewable manufacturing costs up to 200% lower in China, says WoodMac
Wood Mackenzie says in its latest report that low prices and integrated supply chains allow Chinese manufacturers to supply more than 65% of total global demand for renewables equipment, with its exports growing by 35% between 2019 and 2023.
