Aqueous based recycling of perovskite photovoltaics

Cumulative photovoltaic waste highlights the importance of considering waste recycling before the commercialization of emerging photovoltaic technologies. Perovskite photovoltaics are a promising next-generation technology, where recycling their end-of-life waste can reduce the toxic waste and retain resources. Here, we report a low-cost, green solvent-based holistic recycling strategy to restore all valuable components from perovskite photovoltaic waste. We develop an aqueous based perovskite recycling approach which can also rejuvenate degraded perovskites, exhibiting a recycling ratio of 99.0  0.4 wt%. We further extend the scope of recycling to charge-transport layers, substrates, cover glasses and metal electrodes. After repeated degradation-recycling processes, the recycled devices show similar efficiency and stability compared to the fresh devices. Our holistic recycling strategy reduces 96.6% resource depletion and 68.8% human toxicity (cancer effects) impacts associated with perovskite photovoltaics compared to the landfill treatment. With recycling, the levelized cost of electricity decreases by 18.8% for utility-scale systems and by 20.9% for residential systems. This study highlights unique opportunities of perovskite photovoltaics for holistic recycling and paves the way for sustainable perovskite solar economy.
