Our research group continues to lead advancements in perovskite photovoltaic (PV) materials and technologies through high-impact studies addressing sustainability, circularity, and life-cycle implications. Below are key publications and their media coverage:
2025: Nature Paper on Sustainable Recycling of Perovskite Photovoltaics
Our latest paper, “Aqueous-based recycling of perovskite solar cells with high efficiency and low environmental impact,” has been published in Nature. This work presents a holistic aqueous-based recycling strategy that enables the recovery of nearly all essential materials in perovskite photovoltaics, achieving an impressive 99% recycling efficiency. The proposed approach significantly reduces resource depletion (by 96.6%) and human toxicity (by 68.8%) compared to conventional disposal methods. This research is the result of a global collaboration, including team members at Cornell and partners in Sweden, and highlights the potential for a circular solar economy by integrating materials science, energy systems, and AI-driven sustainability solutions.
