R and D project : Flexible photovoltaic cells optimized for high conversion efficiency from indoor to outdoor illumination conditions, used in new wristwatch products

Résumé des résultats (Abstract) (Allemand)

This project aims at developing flexible CIGS photovoltaic (PV) cells optimized for high conversion efficiency from low (indoor) to high (outdoor) illumination intensity, tailored for new generations of innovative wristwatch products. The project includes the development of CIGS PV dials for classic wristwatches, as well as a second generation for solar wristwatches integrating highly flexible CIGS PV cells in the bracelet with conversion efficiencies above 8 % under low illumination intensity.
