LayTec’s in-line process inspection system chosen by CTF Solar for CdS/CdTe PV fab in China

In-situ metrology system maker LayTec AG of Berlin, Germany says that its in-line process inspection system has been chosen by Germany-based CTF Solar – which is owned by CTIEC (part of China National Building Materials Group Corp (CNBM) – for its new 80MW per annum cadmium sulfide (CdS)/cadmium telluride (CdTe) thin-film solar cell production line in China. All key layers of the solar cell structure are monitored regarding production quality and yield.

LayTec delivers a multi-station in-line inspection system. The system inspects the incoming transparent conductive oxide (TCO)-coated float glass and generates valuable statistical process control (SPC) data of the CdS/CdTe solar cell structure through highly precise measurement of relevant film characteristics. The multi-station system is fully integrated into the production line and continuously delivers comprehensive analytical data to the local manufacturing execution system (MES) host.

“CNBM has the highest demands on quality and yield for our new CdS/CdTe fab in Chengdu,” says CTF Solar’s CEO Dr Michael Harr. “The best process knowledge and deviation awareness at the earliest stage is a fundamental keystone for sustainable PV cell production,” he adds. “LayTec’s market-leading technology for inline inspection is essential for our high demands on quality and yield.”
