In December 2024, CTF Solar reached a new milestone: an official solar cell efficiency of 21.28%, certified by the Laboratory for Photovoltaics and Solar Energy Conversion at Coburg University of Applied Sciences.

This confirmed result highlights the strength of our technology and the progress we have made in CdTe solar cell development.

Since then, our R&D team in Dresden has continued to push performance further. We have now measured a new internal record of 21.66%, marking another important step forward.

We are currently working on validating this new result and are optimistic about surpassing it by the end of 2025. CTF Solar remain focused on improving efficiency and bringing high-performance CdTe technology closer to industrial application.
