Rare-earth-free solar cells could lower costs and boost accessibility

Researchers at the University of Sheffield, in collaboration with Power Roll Ltd., have developed a cost-effective, flexible solar cell using a perovskite semiconductor. This innovative design, which consolidates electrical contacts onto the back of the cell, simplifies production and enhances efficiency, making solar power more accessible, especially in regions where conventional panels are impractical.
