SolR: In-Line Monitoring System for Thin Film PV Processes

BERLIN and SAN FRANCISCO, June 23 /PRNewswire/ -- With its brand new product-line SolR, LayTec will provide the first in-line monitoring systems
commercially available for thin film photovoltaic (PV) applications. SolR is
capable of monitoring the film thickness of all layers throughout the
thin-film PV process: transparent conducting oxide (TCO), absorber and buffer
layers. SolR will be available in various editions for copper indium gallium
selenide (CIGS) as well as for CdTe based thin-film solar cell processes.
According to LayTec's chief developer in the PV project, the main challenge
that had to be tackled was to obtain an accurate film thickness measurement
despite the reduced reflectance due to intentionally rough absorber layers.
