Thin film solar cells: New world record for solar cell efficiency READ MORE

Thin film solar cells: New world record for solar cell efficiency: In a remarkable feat, scientists have developed thin film solar cells on flexible polymer foils with a new record efficiency of 20.4% for converting sunlight into electricity. The cells are based on CIGS semiconducting material (copper indium gallium (di)selenide) known for its potential to provide cost-effective solar electricity. The technology is currently awaiting scale-up for industrial applications.
