Technology and R&D

A new Perspectives research study on the future of the global PV supply chain outlines how module prices, performance, and lifetimes could evolve over the next 25 years. The work reflects a collaboration among leading solar research institutions worldwide. One of the study’s authors, the director of the Fraunhofer Institute for Solar Energy Systems (ISE), told pv magazine that solar module and cell efficiencies could exceed 35% by 2050, with panel prices expected to drop by a factor of two.

The use of a novel roll-to-roll process and optimization technology resulted in polymer foils for use in colored PV modules in a potentially wide range of colors with low iridescence and low levels of efficiency loss.

China is on track to reach a fully renewable energy system by 2051, nearly a century earlier than the United States, according to a global study covering 150 countries.

By 2050, sodium-ion batteries with fast learning rates could deliver storage at 11–14 €/MWh – cheaper than lithium-ion at 16–22 €/MWh – while also offering higher energy-to-power ratios and high cycle durability, a new research finds.

New UNSW research found that about 20% of solar modules in large PV plants degrade much faster than expected. They recommend holistic strategies such as robust materials, advanced designs, and proactive monitoring to decouple degradation pathways and prevent cascading failures.

A Husqvarna researcher developed a fast, interpretable PV hotspot-detection method using IR thermography and Lab* color-space features instead of heavy neural networks, achieving up to 95.2% accuracy with shallow classifiers. The lightweight system works in real time on drones or edge devices and could save 17,620 kWh and 8.9 tons of CO₂ annually by improving fault detection in solar panels.

Spain-based Izpitek has developed an 86 kW building-integrated photovoltaics (BIPV) installation for tunnel entrances and exits that supplies power for lighting, demonstrating how solar energy can be adapted to complex architectural environments.

The Chinese perovskite solar technology developer said the result is currently under testing by an unspecified third-party authoritative laboratory in China. The achievement is part of the company’s efforts to bring its perovskite cell technology closer to commercial production.

JinkoSolar has signed a strategic cooperation agreement with XtalPi, an “AI for Science” platform company, to pursue high-throughput R&D on perovskite-crystalline-silicon tandem solar cells using an AI platform and quantum-physics-based models.

UNSW researchers boosted TOPCon solar cell efficiency by locally thinning the rear poly-Si layer, reducing parasitic absorption while preserving wafer integrity. The champion cell built with this approach achieved 25.10% efficiency with improved bifaciality and maintained strong passivation.
