Decades at the
forefront of photovoltaics

Although we’re able to look back on a proud tradition of ground-breaking solar photovoltaic achievements since the birth of the industry, CTF Solar is still gaining momentum.

Highlights

Dr. Dieter Bonnet created the world’s first functional cadmium telluride (CdTe) solar cell in 1969. The technology would remain at the cutting edge of solar photovoltaics nearly a half century later. This cost-efficient thin-film technology is still advancing by leaps and bounds. In cooperation with the Technical University of Darmstadt, CTF Solar recently achieved CdTe cell efficiency of 15.2%. With the new dedicated research facility in Dresden now operational, the stage is set for CTF Solar to continue its string of innovations.
