The CTF Solar R&D team in Dresden has measured a new internal record cell with an efficiency of 20.46 %. For the production of this solar cell only the standard processes were used, which are also available in the production lines, offered by CTF Solar. The cell has an area of 1 cm² and is on a commercial TCO float glass with an additional anti reflection coating.
This is a great success for our international team two years after the move to the new location. After that, numerous and more production-oriented machines were put into operation and the development of the CdTe solar cell was further improved. The combination of optimized processes and numerous analysis methods has made this great step possible.
