​Researchers at Linköping University in Sweden have developed an innovative method to fully recycle modern perovskite solar cells using water as the primary solvent. This breakthrough addresses significant environmental challenges associated with the disposal of conventional silicon-based solar panels, which often end up in landfills due to the absence of efficient recycling technologies. ​

Perovskite solar cells are gaining attention for their cost-effectiveness, lightweight nature, flexibility, and transparency, making them suitable for various applications, such as integration into windows. They can convert up to 25% of solar energy into electricity, rivaling the efficiency of traditional silicon solar cells. ​

The newly developed recycling process allows for the repeated reuse of all components of the solar cell, including covering glasses, electrodes, perovskite layers, and charge transport layers, without compromising performance. Unlike previous methods that relied on toxic solvents like dimethylformamide, this approach utilizes water, making it more environmentally friendly. ​

Given that perovskite solar cells have a shorter lifespan compared to silicon-based ones and contain small amounts of lead necessary for high efficiency, this efficient and eco-friendly recycling method is particularly important. The researchers aim to further develop this technique for larger-scale industrial applications, potentially revolutionizing the sustainability of solar energy technologies. ​
