Germany’s Institute for Solar Energy Research Hamelin has confirmed that Longi’s new heterojunction solar cell has achieved a power conversion efficiency of 26.5% – an improvement of 1.1%.

The battery has a rated output of 5.5 kW and can be installed in outdoor environments. It is equipped with a hybrid power conditioner, a DC-to-DC converter, and a vehicle power supply adapter with a maximum output of 1.1 kWh.

University of Illinois scientists have developed a way to remove snow and ice from solar panels at a much faster rate than conventional approaches. It is based on a glass coating on a film with high optical transparency and superhydrophobicity.

Hanwha announces an investment of $320M in cell and module manufacturing capacity expansions to meet the growing global demand for sustainable energy. 

US researchers have investigated how grid-forming inverters could help to resolve network synchronization issues. They have found that multi-loop devices could offer strong damping support in power systems with intermittent renewables.

The device is described as a heat engine with no moving parts that is able to produce power from a heat source of between 1,900 to 2,400 C. This concept is known as thermal energy grid storage (TEGS) and consists of a low-cost, grid-scale storage technology that uses thermophotovoltaic cells to convert heat to electricity above 2,000 C.

Chinese inverter maker Growatt has launched Infinity 1500, a portable power station for off-grid applications.

Developed by Canadian start-up Salient Energy, the zinc-ion battery has a rated capacity of 60 Ah, a nominal voltage of 1.3 V, and a volumetric energy density of 100 Wh/L.

The device is based on a standard, two-electrode electrochemical cell containing conductive polymers, a carbon-graphene hybrid, and a non-flammable liquid electrolyte. The battery cells were tested to perform for 12,000 cycles at 100% depth of discharge.
