Rooftop bifacial PV can produce over 9% more power than monofacial systems in high-latitudes
A study analyzing urban bifacial PV systems in high-latitude areas found they can generate 9–13% more electricity than monofacial panels under snow conditions, particularly in winter, while also achieving a lower levelized cost of electricity. The research developed a techno-economic optimization model considering snow effects, panel orientation, interrow spacing, and operation modes, highlighting sensitivity to market conditions and discount rates.
Chinese scientists unveil thermoacoustic ultra-high temperature heat pump prototype
Researchers at the Chinese Academy of Sciences developed a thermoacoustic Stirling heat pump prototype that offers high thermal performance, a peak coefficient of performance of 1.68, and potential applications in high-temperature industrial processes, enabling zero-carbon heating for sectors like petrochemicals and metallurgy.
JA Solar expands into energy storage with new subsidiary
The Chinese PV manufacturer is stepping up its energy storage push with a new Beijing subsidiary capitalized at RMB 300 million ($42 million).
Longi backs Carbon’s shift to GW-scale solar production in France
France-based startup Carbon plans to partner with Chinese manufacturer Longi and adopt back-contact (BC) solar technology as it revises its roadmap for a gigawatt-scale solar module factory.
The impact of laser-assisted firing on TOPCon solar cell performance
UNSW and Jolywood studied the thermal stability of laser-assisted fired TOPCon solar cells during module fabrication and high-temperature stress, identifying hydrogen-related defect dynamics as the key factor behind degradation and recovery. They found lamination causes temporary efficiency losses that self-recover under light exposure, while optimized LAF can restore degraded contacts, providing practical guidance for reliable module manufacturing and testing.
GoodWe launches new hybrid inverters for C&I solar
