Contributing to the Development of Cadmium Telluride Solar Cells
Dr. Bettina Sp?th
Joined CNBM in 2010
Vice Director of the R&D Department at CTF Solar
Dr. Bettina Sp?th's distinguished career in science began in Darmstadt, Germany. Growing up in the picturesque town of Bensheim in Hessia, she developed a keen interest in science, which propelled her into the field of material science. Her academic journey started at Darmstadt University, where she honed her expertise in semiconductors, guided by Professor Jaegermann.
Dr. Sp?th's impressive understanding of material science led to her completing her diploma thesis on CdTe thin film solar cells within Professor Jaegermann's "surface science" research group. She then continued her research under the professor's mentorship, pursuing a PhD focused on the interface and back contact properties of CdTe solar cells.
Post-PhD, Dr. Sp?th moved to Dresden, Germany, to apply her material science expertise in the semiconductor industry. Her primary responsibility was to improve and adapt plasma etching processes for the production of memory chips.
Her interest in solar technology drew her back to the solar industry, where she worked on silicon solar cell characterization. Her significant contributions in this field led to her shifting focus back to CdTe (Cadmium Telluride) solar cells, a technology gaining attention for its high conversion efficiency and potential for mass production. In 2010, Dr. Sp?th joined Roth&Rau/CTF Solar, where she leveraged her understanding of materials and semiconductor technology to drive advancements in CdTe solar cell technologies.
At CTF Solar, she took on a significant role, utilizing her knowledge and experience to drive advancements in CdTe solar cell technologies. During this time, she established a close cooperation with the German Fraunhofer Institute FEP.
She set up a research and development department in CTF Solar. This department, initially consisting of 3-4 scientists, laid the foundation for today's 20-person research and development department. Initially located at Fraunhofer FEP/Dresden, Germany, the entire front-end process chain was developed. CTF Solar specified and developed several pilot tools to enable the development on processes to increase the solar cell efficiency.
First, the heart tool CSS coating was put into operation. A chemical department was established and the latest chemical processes were tested. Dr Bettina Sp?th was mainly responsible for the sputtering processes and metrology tools.
At that time, Dr Bettina Sp?th was able to drive forward the development of the metallic copper-free back contact. The first copper-free solar cells with an efficiency of >13% were developed. Several tools from the former laboratory in Kelkheim, Germany were transferred to Dresden and put into operation.
In 2011, CTIEC, part of the Chinese CNBM Group, acquired CTF Solar. The research and development department was growing and therefor moved to a bigger laboratory in the north of Dresden. The laboratory covered an area of 300 m?. Together with her colleagues, Dr. Bettina Sp?th organized the transfer of the tools to the new location. New tools were specified and purchased and a complete upgraded laboratory was established.
Dr. Bettina Sp?th contributed in several founded projects in 2012-2015 and with this help, the CdTe conversion efficiency was rised to >15%. The laboratory processes were transferred into specifications of production tools. As a scientist and process engineer, Dr. Bettina Sp?th supported the specification of the sputtering, lasering and annealing machines as well the metrology tools. This included a close interaction with suppliers as well as several acceptance procedures at several location.
The results of the developments and investigations of Dr. Bettina Sp?th and her colleagues were transferred onto the first production line of CTF Solar in China in 2016. In recognition of her expertise, Dr. Sp?th was promoted to the role of Vice Director in the R&D department of CTF Solar in 2017. She led a team of 20 employees, shaping the company's research agenda and fostering an innovative environment. Her leadership skills and scientific acumen were instrumental in driving the company's success and furthering its reputation. From 2016- 2022 Dr. Bettina led two funded projects, each with a duration of 3 years and a funding of 1.5 million. In 2020 CTF Solar moved again to a new location, covering an area of 1000 m?.
Since 2016, the efficiency of CdTe solar cells has been improved from 17.8% to the remarkable value of 20.85% and that of 10*10 cm? modules from 14.4% to 18.3% in the R&D department of CTF Solar.
After Dr. Sp?th visited the Handan production line in April, she fully supported introducing the ZnTe process. With the technical support from CTF Solar team, the efficiency of CdTe thin film solar module reached 17%. Dr. Sp?th highly commended the hard work of HDN team. With the success of this cooperation, she has full confidence that we together can meet all challenges in the future. She believes that the prospect of CdTe solar cells market will be broader through everyone's efforts.

Generating Creative Ideas in Cultural Fusion
Dr. Jens Heinrich
Joined CNBM in 2016
Director od Technology Development of CTF Solar
In 1990, Jens Heinrich started studies in chemistry at Chemnitz University of Technology in Germany. After getting a master’s degree in chemistry, he continued to get a PhD in physical chemistry, focusing on the studies of chemical vapor deposition. Starting his career in the semiconductor industry as a manufacturing and process engineer, he then assumed several other roles including a process integration engineer and a technology transfer engineer in companies like AMD/ Global Foundries and Intel, gaining technical and cultural experiences in different countries.
In early 2016, Dr. Heinrich decided to move into a different technology area with the aim of learning new technologies and providing support to the new company. He joined CTF Solar as a process transfer manager with the aim of applying his experience and skillsets to a different industry. He described the start at CTF Solar as really exciting, developing a new team together with head of the process engineering department – and designing a factory for large scale PV modules based on CTF’s CdTe technology – almost from scratch. Together with the colleagues from CTIEC, they started the project of the 1st CdTe factory for large size modules (> 1m? – almost 2m?) in Chengdu, southwest China’s Sichuan Province. His 1st trip to China for CTF Solar was totally different from his previous experiences. He was impressed by a very warm welcome and great hospitality he received, as well as open discussions about the best way to achieve the shared goals of the project. Of course, it was not all easy and very soon the team realized that the cultural differences between Germany and China could cause problems and misunderstandings, but everyone was open minded and willing to learn and adapt. In a very short time, the goals were set to try to combine the strengths of both cultures for the success of the project. Soon after the start of the construction, the 1st project milestone (equipment design reviews, initial acceptance tests) was passed and by the end of the year 2016, the 1st part of the production line had been moved into the factory building, while construction work still in progress. Together with most of the CTF Solar’s engineers, scientists and managers, Dr. Heinrich travelled to Chengdu multiple times, supervising the equipment’s installation and commissioning, solving problems onsite, ensuring the support and collaboration from the different suppliers. Finally, in August 2017, less than one year after completing the design review, the main deposition equipment (CSS – a co-development between CTF Solar and equipment supplier) successfully completed trial operation and produced the first functional midule on Agust 24, 2017. It was the 1st CdTe module for CNBM group and the 1st large size thin film module worldwide. After the successful demonstration of the CdTe technologies capabilities on manufacturing scale, more CdTe factory projects for CTIEC and CTF Solar have been launched.
In 2018, Dr. Heinrich got promoted to deputy head of process engineering. His focus and work tasks shifted more to building and developing the CTF Solar’s engineering team, implementing technology changes as well as ramping up and improving current and future factory projects. These new challenges required an even deeper collaboration with the colleagues and partners from CTIEC and with the CNBM factory operations teams. Here, support from Chinese colleagues within CTF Solar, especially from the CTIEC management, project team and the engineering team played an important role in his success.
2020 and the following years were packed with challenges for each team member of CTF Solar and for Dr Heinrich himself. Despite the impact of COVID-19 to the personal life, especially the CTF factory project business was affected. Most of the projects got delayed due to this pandemic situation and CTF Solar had to adapt to the new situation where they could not go to the sites. In this process, the benefits of a multinational team became obvious.
Despite the impact of the COVID-19 pandemic, Dr. Heinrich and his team persevered and adapted to new circumstances, receiving significant support from CTIEC and CNBM colleagues. As one of the two non-Chinese speaking CTF employees, he visited the factory in China twice during COVID-19 outbreak. This crisis highlighted the strength of their multinational team. Now technical development of factory sites has been continuously improved and enhanced, and the team and most of the projects are back on track. With the support from Mr. Yin, CTF Solar started to build a team of engineers within China and introduced new process and equipment to the Handan factory, which will dramatically improve the performance of the PV modules with respect to efficiency and stability.
Through the efforts of the HDOM, CTIEC and CTF teams, the heromodule with photoelectric conversion efficiency of more than 330W were produced, which is 10% more efficient than the previous record, and 15% more effienct than the current product average. This major achievement makes all the CTF Solar colleagues proud of being a member of this CNBM team.
In early 2023, Dr. Heinrich became a member of the CTF Solar Management board, allowing him to have a substantial say on CTF's further development and business, and contribute to CTIEC's and CNBM's success. He now looks forward to future challenges and is confident in the team's ability to continue innovating and contributing to the rapidly growing market of Building Integrated Photovoltaic (BIPV).
