Abstract
We have developed a new application of GT-FabScan for rapid mapping of AR coatings on Si solar cells. The system generates an image of the AR thickness and presents it in a color format using false colors. This measurement is made in less than 100 ms. The development of this application enables the system to generate thickness maps of the AR coating to determine the repeatability of thedeposition system, as well as to ensure that downstream processing can be controlled. These data can also be used to determine the average thickness of the coating. Downstream processing is an important issue in current solar cell technology (as discussed below). This paper describes its importance to the PV industry and discusses the principles and method of this measurement.
