Flexible CIGS

Cutting out cadmium for a 16.7%-efficient flexible thin-film solar cell

Scientists in Japan have developed new processes for CIGS solar cell manufacturing, entirely eliminating the use of cadmium and replacing a waste-intensive wet chemical stage. With a thin film deposited on a flexible steel substrate, the group achieved 16.7% efficiency, which it says is a record for a cell of this type produced using scalable fabrication processes.
