ÅMA & WISE Join Forces to Transform Industrial Recycling
Can smarter recycling pave the way for a more sustainable industry?

“Even after undergoing multiple cycles of degradation and recycling, the recovered devices work just as well and last as long as new ones. This approach is also great for the environment and saves money — it uses 96.6% fewer resources and reduces cancer-related health risks by 68.8%”, says Prof. Feng Gao from Linköping University.

Perovskite solar cells—named after perovskite materials—are one of the most promising next-generation photovoltaic (PV) technologies. They show potential for high efficiency and low production costs. But as we have learned from the evolution of conventional silicon PVs, developing recycling technologies for a sustainable PV system is essential before commercialization. For perovskite PVs in particular, recycling is not just about resource recovery—it is also a critical step in reducing lead use and safely managing the toxic lead-containing waste these devices can generate. Adding to the urgency, global regulations are increasingly placing responsibility on PV manufacturers to collect and recycle their end-of-life products.
In a recent Nature article, “Aqueous-based recycling of perovskite photovoltaics” [Nature 638, 670–675 (2025)], Professor Feng Gao, Xun Xiao and collaborators at Linköping University present an environmentally friendly recycling strategy for perovskite PVs. Their strategy uses a water-based solvent to recover nearly all key functional materials in the module—including the hole and electron transport layers, the perovskite absorber layer, indium tin oxide substrates, and cover glass—with high efficiency and purity.
– We immerse degraded perovskites into an aqueous solution for repairing and reclaiming high-quality perovskite crystals. This approach has achieved an impressive 99.0 ± 0.4 wt% recycling efficiency, says Prof. Feng Gao, WISE-affiliated researcher and optoelectronics professor at Linköping University.
Even after undergoing multiple cycles of degradation and recycling, the recovered devices show comparable efficiency and stability to brand-new ones. Beyond technical performance, the strategy also delivers strong environmental and economic benefits: it reduces resource depletion by 96.6% and cuts human toxicity impacts (cancer-related) by 68.8%, compared to landfill disposal. Plus, it helps lower the levelized cost of electricity for both residential and utility-scale systems.
Prof. Feng Gao’s and collaborators’ article “Aqueous-based recycling of perovskite photovoltaics” is published in Nature, [Nature 638, 670-675 (2025)].

An international team of scientists from France, Germany, and Sweden has taken a closer look at how magnetism can change incredibly fast—a phenomenon called ultrafast demagnetization.
For the first time, they were able to observe some of the key steps in this process as it happens in a magnetic material. Their work, published in Nature Communications, could help pave the way for faster and more energy-efficient spintronic devices used for storing and processing information.
