AI-assisted method maps PV module losses from a single luminescence image
An international research team has developed an AI-assisted method that quantifies PV module power losses from a single luminescence image. The approach achieved an overall error of about 0.5% in tests on 300 field-retrieved modules and was demonstrated using drone-based imaging at a 186 kW solar farm.
Scientists build 33.3%-efficient perovskite-silicon tandem solar cell processed in ambient air
Chinese researchers developed a PNCC polymer hole-transport layer that enables efficient and stable perovskite solar cells to be fabricated under ambient conditions. The material was used in a perovskite-silicon tandem cell that achieved 33.3% efficiency and a certified efficiency of 33.0%.
Scientists build 17%-efficient semi-transparent perovskite solar cell based on sputter-resistant aluminum oxide layer
Researchers replaced the conventional 20 nm SnOₓ buffer layer with just 3 nm of ALD-deposited AlOₓ, which protected inverted perovskite cells from ITO sputtering damage while maintaining efficient charge extraction. The resulting devices achieved efficiencies above 17% in semi-transparent cells and 26% in perovskite-silicon tandems, while reducing material use and fabrication time.

Researchers build 27.39%-efficient inverted perovskite solar cell based on new molecular design
Chinese researchers have developed a molecular additive that reduces defects in perovskite solar cells, enabling a power conversion efficiency of 27.39%. The approach was also used in bifacial mini-modules with efficiencies above 22% and 99.6% power retention after more than 5,000 hours of continuous operation.
New research confirms negligible LeTID degradation in TOPCon solar cells
Researchers have found that light- and elevated-temperature-induced degradation (LeTID) has a limited impact on n-type TOPCon solar cells compared with earlier p-type PERC technology. Optimized firing conditions and laser-enhanced contact optimisation can further suppress degradation, with industrial TOPCon cells showing efficiency losses within acceptable warranty tolerances.
Researchers team with Queensland manufacturer to drive perovskite-silicon tandem solar cell development
University of Sydney researchers will team with a Queensland-based solar panel manufacturer to accelerate the commercialisation of next-generation silicon-perovskite tandem solar cell technology after securing $7.25 million in federal government funding via the Australian Renewable Energy Agency.
