Highest-efficiency flexible thin-film solar cells | Kurzweil AI

Scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have developed thin-film solar cells on flexible polymer foils with a new record efficiency of 20.4%.

The cells are based on CIGS  (copper indium gallium (di)selenide) semiconducting material.

Thin-film, lightweight, flexible high-performance solar modules are attractive for solar farms, roofs and facades of buildings, automobiles, and portable electronics and can be produced using continuous roll-to-roll manufacturing processes that offer further cost reductions compared to standard silicon technologies.

“The next step will be to scale up the roll-to-roll manufacturing process with an industrial partner,” Flisom, says Empa Director Gian-Luca Bona.

The research is supported by the Swiss National Science Foundation (SNSF), the Commission for Technology and Innovation (CTI), the Swiss Federal Office of Energy (SFOE) and the EU Framework Programmes.
