Researchers in Singapore have built a triple junction tandem solar cell with an ultrawide-bandgap perovskite absorber integrating cyanate (OCN) ions. The cell surpassed the power conversion efficiencies previously reported for all other perovskite-based triple-junction tandems, as well as single-junction perovskite and silicon solar cells.

REC has developed a new series of residential heterojunction solar panels with efficiencies ranging from 20.6% to 22.2% and an operating temperature coefficient of -0.24% per degree Celsius.

Leapton says its new panels have a temperature coefficient of -0.30% per C and an efficiency of up to 22.65%. They come with a 30-year power output guarantee for 87.4% of the initial yield.

In updated figures, BloombergNEF finds that 444 GW of new PV capacity was installed globally in 2023. It says new installations could reach up to 574 GW this year, in its most optimistic forecast, 627 GW in 2025, and 880 GW in 2030.

Sharp has developed vehicle-to-home (V2H) electric-vehicle chargers for PV-powered homes, featuring 6 kW of charging/discharging rated power and an input DC voltage of 340 V. The wall-mounted devices are suitable for indoor and outdoor environments.

The Dutch government has submitted a public proposal to support the production of heterojunction and perovskite-silicon tandem modules, as well as building- and vehicle-integrated PV panels, with a maximum allocation of €70 million (USD75.1 million) per solar manufacturing project.

LG has developed two versions of its new enblock E storage system, each with usable energy capacities of 12.4 kWh and 15.5 kWh. It says the two models, sized at 451 mm x 330 mm, can be easily deployed in small spaces.

New research from Belgium shows the importance of assessing inverter reliability by including climate-based PV panel degradation rates. The scientists found that, especially in hot and arid climates, PV inverters should be designed with parameters above the standard value.

While investigating on the effects of wildfire smoke on rooftop PV installations, University of New South Wales (UNSW) researchers have found that solar arrays, due to their sensitivity to smoke, could serve as an early warning detection of wildfires by providing temporal and spatial information on the presence and approximate concentrations of smoke.

Sharp’s new IEC61215- and IEC61730-certified solar panels have an operating temperature coefficient of -0.30% per C and a bifaciality factor of over 80%.
