Indoor solar panels to power your gadgets? A team just proved it can be done safely

University of Queensland researchers developed a lead-free indoor perovskite solar cell using a solvent-free vapor process.

The device reached a record 16.36% power conversion efficiency under indoor light.

The approach avoids hazardous solvents and could be easier to manufacture safely at scale.

Researchers are testing it as a power source for small electronics, wearables, sensors, and shelf labels.

The advance could reduce reliance on coin-cell and button batteries in low-power devices.
