The US Department of Energy’s National Renewable Energy Laboratory (NREL) has confirmed Longi’s achievement of a world record-breaking efficiency rating of 33.9% for a perovskite-silicon tandem solar cell.

The “Folie40” project involves backsheet makers, solar module manufacturers, and research institutions such as Folienwerk Wolfen, Meyer Burger, Aluminum Féron, Fraunhofer ISE, and the Anhalt University of Applied Sciences.

The Chinese Academy of Sciences has unveiled a high-efficiency perovskite solar cell with a purported peak efficiency rating of 26.1%, by using 1-(Phenylsulfonyl)pyrrole (PSP) as an additive. The cell is third-party certified with an efficiency of 25.2%, and it maintains 92% of its original efficiency after 2,500 hours of operation.

In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.

A Finnish-German research group has developed a 6 × 6 mm low bandgap GaAsNBi solar cell with an active area of 0.25 cm2. The device has an energy bandgap of 0.86 eV and is reportedly suitable for applications in multi-junction solar cells.

Globeleq says that commercial operations have started for what is said to be Mozambique’s first combined utility-scale solar and energy storage plant, in the district of Cuamba.

German engineering association the VDMA reports strong PV equipment exports in the second quarter, representing 92.5% of sales. Overall, PV equipment sales were up by 50% compared to the first quarter of the year and up slightly compared to the same period last year, but incoming orders for PV equipment were down by 14%.

At the recent pv magazine RoundtablesUS 2023 event, four experts weighed in on PV module choices now and into the future, with TOPCon in the spotlight, but perovskite and tandem HJT on the not-too-distant horizon.

Drone-mounted imaging of solar farm performance at the rate of one panel per second reduces the cost of current ground-based sampling methods by up to 20 times. A new strategic Australia-Singapore partnership is helping to ensure the output of PV assets is always at peak.

US-based thin-film PV manufacturer First Solar says it has raised its expectations for 2023 as its order backlog continues to grow.
