Canadian Solar is offering six versions of its 132-cell TOPBiHiKu7 solar modules, with power outputs ranging from 675 W to 700 W and efficiencies ranging from 21.7% to 22.5%. They have an efficiency range of 26.1% to 27.0%, with a bifacial gain of 20%.

The researchers deposited reduced graphene oxide (rGO) and zinc oxide (ZnO) nanowires over seaweed cellulose to make the anode material for the supercapacitor. The device exhibited a greater energy density of 5.21 Wh/kg, a series resistance of 2.16 ohms, and no air degradation even after 5,000 cycles.  

Maxeon Solar Technologies has filed a lawsuit against Tongwei Solar in Germany’s Dusseldorf district court for the alleged infringement of its European patent for shingled solar cell technology.

The European Solar Test Installation (ESTI) has confirmed the results of Longi’s new perovskite/silicon tandem solar cell. It is currently the second-highest efficiency record in the world for a perovskite/silicon tandem cell.

Jordanian researchers have developed a method using acrylic sheets to reflect and absorb unused solar radiation in PV power generation. The solution has the potential to decrease solar panel temperature by more than 14% and increase power yields by approximately 2%.

First Solar has announced a limited production run of the “world’s first” bifacial solar panel with a cadmium telluride (CdTe) semiconductor. The pre-commercial Series 6 Plus Bifacial module is making its debut this week at Intersolar Europe in Munich, Germany.

A research group in Ghana has conducted a series of tests to assess the performance of polycrystalline solar modules in PV systems operating in their home country for at least 5 years. They found that the vast majority of the panels may ‘fail’ before 20 years in operation under outdoor conditions.

An Italian research group has assessed the advantages of combining solar power generation in greenhouses with vertical farming. The scientists claim this new approach offers better land use while increasing agricultural yield.

Chinese manufacturer Akcome has released a new line of heterojunction solar panels with a nominal power capacity ranging between 710 W and 730 W and a conversion efficiency of 22.80% to 23.50%.

Scientists in Belgium are exploring the potential of recycled silicon in solar modules at the end of their life cycle for reuse in low-cost, higher-energy-density storage technologies. They claim EV batteries using this silicon may allow faster recharging and travel longer distances on a single charge.
