Researchers from Linköping University in Sweden believe they may have found a solution that could let solar manufacturers have their cake and eat it too. Using a newly designed recycling technique, the researchers were able to fully break down a perovskite solar cell at the end of its life cycle using only a water solvent.

In a study published in Nature, researchers at Linköping University, Sweden, have developed a method to recycle all parts of a solar cell repeatedly without environmentally hazardous solvents. The recycled solar cell has the same efficiency as the original one.

A new technique from Linköping University recycles perovskite solar cells using water, ensuring eco-friendly processes and identical performance to originals.
