Mellow Energy claims its ML-Flex panel is currently the world’s largest flexible perovskite solar module. Available in five versions with power output ranging from 260 W to 300 W, the module measures 1,200 mm x 1,600 mm and weighs only 2.04 kg.

Huasun has launched its 720 W Kunlun G12 dual-glass bifacial solar panels for vertical PV projects at the World Future Economic Summit in Abu Dhabi. The panels feature a 23.2% power conversion efficiency and enhanced mechanical stress resistance with a steel alloy frame.

Techno-economic analysis conducted by NREL researchers has shown how perovskite-silicon tandem solar modules could currently hardly compete in cost with incumbent PV panels. Production costs for U.S.-made tandem products were found to range between $0.29/W and $0.42/W, with module efficiencies ranging from 25% to 30%.

The result was confirmed by the Shanghai Institute of Microsystem and Information Technology under the Chinese Academy of Sciences (CAS).

University of New South Wales researchers investigated the impact of sodium-induced degradation in heterojunction solar cells under accelerated damp-heat testing. They considered three different types of sodium salts and identified the degradation mechanisms attributed to each contaminant.

Scientists in the Netherlands proposed a new testing scheme for recycling silicon from end-of-life photovoltaic panels. Their methodology helped create different wafer categories for recycling silicon for new ingot production but also showed that most of recycled silicon in the near future will come from p-type products, which will harldy be reutilized in a market now dominated by n-type modules.

IIT Bombay researchers have shown that bifacial perovskite solar cells can achieve a 2% higher power conversion efficiency with a tilt angle of 20 degrees. They also developed a bifacial perovskite solar cell for applications in both tandem or single-junction PV devices.

The German wafer manufacturer said the efficiency was achieved with an unspecified M6 HJT commercial production line, without specifying if the result was certified by an independent third party.

Researchers from Egypt and the UK developed a new floating PV system concept that utilizes compressed air for energy storage. The system has a roundtrip efficiency of 34.1% and an exergy efficiency of 41%.

Hungary installed 1.3 GW of solar between January and October, bringing its cumulative PV capacity to 7.3 GW by the end of October, according to new government data.
