Optimizing Approach for Thin-Film PV Production

FuturePV, April Issue 2011,

In current thin-film solar manufacturing, module quality and process conditions are primarily determined by physical metrics and the final electrical metrics of the product, the solar module. For established, well-known manufacturing processes such as optical disc, this is feasible because the effects and causes of defects have been thoroughly studied and documented. For thin-film PV production, however, this is not the case, which leads to several shortcomings in process control and production optimization. This article shows one optimization approach and some of its pitfalls and proposes a quality indicator. read more...
