China’s new PV industry standards unlikely to resolve overcapacity
pv magazine spoke with two OPIS analysts about China’s new mandatory energy consumption and efficiency standards for the solar sector, which aim to address overcapacity but are unlikely to resolve supply-demand imbalances alone. They said the measures could accelerate the phaseout of outdated capacity and support higher-quality manufacturing, but their impact on operating capacity, module prices and industry consolidation is expected to remain limited in the near term.
ISC Konstanz study highlights atomic layer deposition as a superior approach for TOPCon UV stability
Researchers at ISC Konstanz found that ALD-based aluminum oxide (AlOx) passivation layers provide better UV stability for TOPCon solar cells than PECVD-deposited layers, with thicker AlOx films and a thermally grown SiOx interlayer further improving resistance to UV-induced degradation. Testing laboratory and commercial TOPCon cells showed 2–3% average efficiency losses after high UV exposure, while process variations and layer non-uniformities were identified as key factors influencing long-term UV susceptibility.
Chinese scientists achieve world record efficiency of 28.04% for perovksite-organic tandem solar cell
Researchers at the Chinese Academy of Sciences have reported a perovskite–organic tandem solar cell with a claimed record efficiency of 28.04%, using a photo-transformable TDB molecule to improve perovskite film quality and device stability.

Sungrow, TÜV Rheinland release long-term inverter reliability testing standards
Sungrow and TÜV Rheinland have introduced corporate standards for long-term PV inverter reliability testing, establishing quantitative methodologies to assess component and system durability while expanding their collaboration on technical standards for renewable energy equipment.
U.S. solar LCOE on the rise, says Lazard
Utility-scale solar PV remains one of the lowest-cost sources of new electricity despite an 18% year-on-year increase in unsubsidized LCOE to $40–98/MWh, driven by higher capital costs, interest rates, tariffs, and supply chain pressures. Over the long term, however, utility-scale solar maintains a strong cost advantage over most conventional and alternative generation technologies.
Triple-junction all-perovskite solar cell based on graphene oxide bilayer achieves 27.3% efficiency
An international research team developed a triple-junction all-perovskite solar cell using a graphene oxide (GO)/self-assembled monolayer (SAM) bilayer contact strategy to overcome SAM-related charge extraction losses and improve interface quality.
