Large-area thin films with minimal defects

Nano-scale thin films have become an important component of many products. Novel optical technology to detect and repair defects during production will enhance quality and durability, and boost EU competitiveness.

Small defects in thin films used in products such as polymer-coated paper and low-cost, flexible photovoltaics (PVs) can decrease product quality and durability. This also reduces yield and increases scrap levels, further affecting competitiveness. Exposure of such defective PV modules and polymer-coated paperboard barrier films to water vapour causes short circuits in electronics and the degradation of paper products.
