A Canadian consortium led by the Sherbrooke University has developed a CPV panel with improved light absorption through a microstructured anti-reflecting coating consisting of a monolayer of silica beads, which they claim can improve the device’s short-circuit current by up to 3.7%. The module is based on III-V solar cells.

Green hydrogen cost may reach between €0.7 and €1.8/kg by 2030 and €0.3 and €0.9/kg by 2050, according to a European research team led by the European Technology and Innovation Platform for Photovoltaics. The scientists found that the levelized cost of hydrogen (LCOH) could drop from around €0.031-0.081/kWh currently to €0.02-0.05 by 2030 and €0.01-0.027 by 2050.

The Massachusetts Clean Energy Center (MassCEC) showed, through a pilot incentive program, that whole-home heat pumps are a feasible solution for heating when switching from gas. Project costs, however, were found to be higher than expected.

The modular power station comes with two lithium iron phosphate (LFP) batteries and has a capacity of 6 kW/24.6 kWh. It relies on a 3 kW pure sine wave inverter which the manufacturer said is able to adjust the AC charging rate.

The module is claimed to be one of the top five most performant heterojunction solar modules, in terms of power density, with the champion panel achieving 214.15 W/m² and the average device 209.5 W/m². The panel showed an efficiency ranging from 20.95% to 21.41%.

Developed by U.S. scientists, the 10%-efficient device is intended for applications in solar windows and promises efficiencies close to 15%. According to its creators, the cell retained 80% of its efficiency after 1,900 hours at 55 degrees Celsius.

Solar Team Eindhoven has developed an experimental mobile house that is powered exclusively by vehicle-integrated PV and is claimed to achieve a range of 730km, on a sunny day and at a, moderate speed of up to 85kph. The vehicle is equipped with a foldable PV system that can be unfolded and produce more power when the vehicle is not in motion.

South Korean researchers have tested four operational modes to combine residential batteries with balcony PV modules and have found that the best configuration is when solar is supplied to the load after the battery is fully charged. Charging the battery with the grid prevents the risk of full discharge in the absence of PV power, they said.

WattEV will build 1 MW solar-powered chargers to deliver 320 miles (515 km) of range to Class 8, 80,000-pound trucks in 30 minutes.

BayWa r.e. and the Fraunhofer Institute for Solar Energy Systems ISE have built a 258 kW agrivoltaic system that hosts apple cultivation under four different crop protection systems. The system utilizes agrivoltaic technology with permanent, light-permeable PV modules that block rain, and tracking PV module tech that blocks rain only if necessary.
