Monitoring System suits thin film PV applications.
July 7, 2009 -
Designed for in-line use, SolR is capable of monitoring film thickness of all layers throughout thin-film photovoltaic process, including transparent conducting oxide, absorber, and buffer layers. System is available in various editions for copper indium gallium selenide and CdTe-based thin-film solar cell processes. It is compatible with in-line and roll-to-roll processes and works on all different kinds of substrates and PV cell designs.
SolR: In-Line Monitoring System for Thin Film PV Processes
LayTec, the major provider of in-situ monitoring equipment to the compound semiconductor industry, is entering a new field of business.
BERLIN and SAN FRANCISCO, June 23 /-- 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.
Today, measurements in thin film PV processes are mainly performed off-line and not on each batch. "SolR will help thin-film PV producers to control their production on-line and thereby enhance their yield. Besides, it will accelerate development cycles and help to transfer established processes to new lines, an important feature in times when thin-film PV industry grows rapidly," LayTec's CEO Thomas Zettler said.
SolR is designed to be compatible with typical state of the art in-line and roll-to-roll processes and to work on all different kinds of substrates and current PV cell designs.
LayTec will present the latest development results at Intersolar North America at the Innovation Exchange Alcove in the exhibition area during the exhibition on 14-16 July 2009 (see the Event Directory for exact time and location).
