Perovskite-silicon tandem solar cell treated with n-Butanol achieves 29.4% efficiency
Researchers in China have built a tandem-perovskite solar cell with a top perovskite device based on an absorber treated with n-butanol, which reportedly reduces the detrimental effects of moisture in manufacturing processes carried out in air environment. The result is a tandem cell with improved charge collection.
Philippines opens nation’s biggest solar-powered irrigation system
The authorities in the Philippines have inaugurated the country’s largest solar-powered irrigation system, featuring more than 1,000 solar panels and two submersible pumps. The system benefits over 200 farmers and is the first of its kind to be constructed over an irrigation canal, preserving farming land.
Canary Islands to host hybrid storage project for synchronous grid-forming
Elewit, the tech platform of Spain’s Red Eléctrica de España (REE), has revealed plans to build a hybrid storage project in the Canary Islands, featuring an 18.8 MVA virtual synchronous compensator and a 16 MW hybrid solution based on ultracapacitors.
Winaico presents bifacial 435 W TOPCon solar modules with 22.30% efficiency
Taiwanese manufacturer Winaico said its newest bifacial, n-type, glass-glass TOPCon compact modules are available in a 435 W aluminum-framed version, and a 430 W full-black version. The module efficiency is up to 22.30%.
U.S. startup launches online platform for residential PV system purchase
Two-year old Monalee has developed an online platform for U.S. homeowners looking to buy solar PV and storage systems. Its software enables the process from quotes to financing, installation, and after-sales support.
Carbon-based perovskite solar cell relying on phosphorene achieves 15.58% efficiency
The result is the best efficiency ever recorded for a carbon-based PV cell using unconventional hole transporting materials to date. The device was built with a hole transparent layer based on electrochemically produced large-area phosphorene flakes, which reportedly enable the required band energy alignment within the cell.
New solid state zinc battery with superb cycle performance
Researchers in Australia have developed a new class of solid electrolytes for rechargeable aqueous zinc-iodine batteries, which has allowed for extended lifespan and high-efficiency. Symmetric cells employing this electrolyte have demonstrated excellent cycle performance, maintaining stability for approximately 5,000 hours at room temperature, while all-solid-state ZnI2 batteries exhibit over 7,000 cycles with a capacity retention exceeding 72.2%
The Hydrogen Stream: China may hit 2025 green-hydrogen targets a year early
Rystad Energy says China appears set to smash its national hydrogen targets, solidifying its lead in the global electrolyzer market, while European Union and Japan have agreed to cooperate on hydrogen research.
Spanish startup offers pre-assembled vertical rooftop PV systems equipped with reflectors
FutureVoltaics says it has developed pre-assembled, reflector-based vertical rooftop PV systems. The systems feature 175 W heterojunction bifacial solar modules and special reflectors on both sides.
Solar modules deployed in France in 1992 still provide 79.5% of original output power
New testing conducted at France’s oldest PV system have shown that its solar modules can still provide performance values in line with what the manufacturers promised.
