Japanese consortium demonstrates transparent PV windows in indoor environment
Nippon Sheet Glass (NSG), Japan’s largest glassmaker, plans to show photovoltaic windows developed by its US unit, Ubiquitous Energy, at a train station in Japan. The windows feature a transparent photovoltaic coating with an invisible element of power generation, capable of absorbing non-visible wavelengths.
Antimony trisulfide PV cell hits 4.9% efficiency with fluorene-based HTMs
An international research group used the ultrasonic spray pyrolysis (USP) method to fabricate an antimony trisulfide PV cell with high power conversion efficiency and remarkable average visible transmittance. The cell has an active area of 7.06 mm2.
Fraunhofer ISE produces hydrogen via PEM electrolyzer with seawater
Fraunhofer ISE scientists have optimized a technical concept for a hydrogen plant at sea. They claim that their design is “technically and economically viable.”
Study shows n-type bifacial TOPCon cells more prone to degradation than p-type
Dutch scientists have reported higher degradation risk for n-type TOPCon cells with EVA encapsulant due to potential moisture degradation. Front-side metallization makes n-type cells more vulnerable than p-type cells, according to damp heat tests.
Role of hydrogen, batteries in UK’s decarbonization efforts
Hydrogen and battery technologies are expected to play an increasingly vital role in the UK’s transition to net zero by 2050, but the varying time scales of their rollouts are driving uncertainty in predicted market share profiles over time, according to a new report.
Heat pump, PV savings in German residential home
pv magazine speaks to Tim Riedel, who owns a 24 kW residential rooftop PV system and a 12.86 kW air-source heat pump, about the return on investment for air-source heat pumps and the savings households can achieve by pairing them with PV.
Photovoltaics for conveyor belts
Sinn Power and Recom have installed a 1 km-long PV system on a conveyor belt at a German gravel plant, using Sinn Power’s custom aluminum structure for conveyor belt applications.
Fire at Australian solar farm
A fire broke out on Monday at the 110 MW Beryl Solar Farm in New South Wales, Australia, causing damages that are still being assessed. Emergency services were able to quickly bring the blaze under control and the unaffected areas of the solar farm are now back online.
South Korean startup offers portable, combinable solar chargers
Hanvixolar says four solar modules require about 5 hours of charging time to fully charge a smartphone. The mini panels use interdigitated back-contact solar cells from US manufacturer Maxeon.
