AEG releases 445 W all-black TOPCon solar module with 22.27% efficiency
AEG is offering three versions of its new all-black solar panels, with power outputs of 435 W to 445 W and efficiency ratings ranging from 21.5% to 22.0%. They feature 108 half-cut monocrystalline cells with n-type technology.
New multilevel PV inverter concept based on switched capacitors, single DC input
Scientists in India have developed a 500 W seven-level inverter prototype based on switched capacitors. The device is reportedly able to achieve a high efficiency despite switching, conduction, and capacitor voltage ripple losses.
Sparc Hydrogen tests prototype photocatalytic water-splitting reactor
Sparc Hydrogen has successfully tested a green hydrogen tech prototype and is now advancing to a pilot plant study near Adelaide, Australia.
Perovskite-silicon tandem solar cells provide extra protection against reverse-bias degradation
An international research team demonstrated that monolithic perovskite-silicon tandem cells do not suffer the same degree of reverse bias degradation that is typically seen in perovskite single junction solar cells under partial shading. They explained that the tandem devices are “protected” by the silicon subcell.
Serbia’s Domi Eko commissions 150 MW TOPCon solar module factory
The factory is located in Velika Plana, central Serbia. The production equipment was provided by Italian manufacturer Ecoprogetti.
Infinite Turbine debuts heat pump turbine for homes, businesses
Infinite Turbine has developed a heat pump turbine for residential and commercial applications, using PV or alternative electricity sources for simultaneous cooling and hydraulic power. The tech can be retrofitted with existing CO2 heat pump systems for air conditioning, hot water, and process heat.
Studer unveils 3-phase distribution cabinet for solar-plus-storage
Switzerland-based Studer says its new infra product can include up to 24 kW of solar and 30 kWh of battery storage. The system has two 12 kW inputs for solar panels and uses 5 kWh batteries from Italian manufacturer Weco.
Dutch startup unveils 600 W two-module residential rooftop PV system
Netherlands-based developer of lightweight PV systems, Rable Group, claims its new rooftop PV solution can be installed in 20 minutes without the need for special permitting or modifications to the fuse box.
First attempt to build back-contact micrometric III-V photovoltaic cells
An international research group has utilized through-substrate-vias to create 3D interconnections in III-V solar cells with a triple-junction architecture. The novel cell design was found to have a low shading factor of below 3% and a 6-fold increase in wafer area use compared to cells based on 2D interconnects.
China’s State Grid commissions 1.2 GW pumped hydro project
