LID Scope - monitoring Light Induced Degradation (LID)

Berlin, (PresseBox) - LayTec is proud to announce the market launch of LID Scope - the first commercially available system for simulation and monitoring of LID! LID Scope is a table-top system that helps to quantify the expected performance loss of any solar cell directly at the line or in the lab. The tool performs accelerated or real-life degradation tests fully automatically. It delivers highly reproducible results and a permanent monitoring of Voc changes by integrated metrology. These features make the tool an inevitable part of quality control and production optimization in PV industry.

LID Scope degrades cells in a well-controlled procedure with electrical current and high temperatures by applying novel physical models developed by Fraunhofer Center for Silicon Photovoltaics (CSP) in Germany (patent pending). For the first time, cells can be degraded in a repeatable way, which means that LID Scope offers identical LID performance control from line to line and from lab to lab.

Tobias Schenk, president of LayTec in-line GmbH, commented: "Since the LID effect has a direct influence on the price-per-watt, LID Scope will affect the negotiations of cell producers and their customers. They can now refer to ‘standardized’ degradation procedure and exactly quantify the loss, thus eliminating costly safety margins."

Dr. Dominik Lausch, the researcher at Fraunhofer CSP, said: "Because LID is an obstacle that will threaten the PERC business, a lot of techniques have been and will be developed to prevent the loss of solar cell performance in field. With LID Scope, manufacturers can control the degree of success of these methods and optimize their production processes much faster and easier."
