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.
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.
Dr. Michael Harr was the driving force behind the creation of CTF Solar in 2008. He was General Manager until end of 2020 and still is an important advisor for further developments. He was previously a founder and the General Manager of ANTEC Solar GmbH in Arnstadt, Germany. There, he successfully managed the construction of the world’s first commercial CdTe solar module factory. In 1993, with a team including Dr. Dieter Bonnet, he set up ANTEC GmbH as a management buyout from the Battelle Institute with the aim of applying CdTe and other technologies to an industrial production process.
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.
