Organic photovoltaics (OPV) and Perovskite-based systems are creating radically new applications in consumer electronics. They include indoor light harvesting to extend battery life of wearables, and outdoor energy generation with performance in regard of their flexibility previously unimaginable from conventional photovoltaics. The same is true for flexible electronics. A key contributor to these advancements has come from progress in bonding technologies. Panacol (Steinbach, Germany) accompanies these developments by providing high tech adhesives that elevate flexible photovoltaics to the next level.

The coating of flexible substrates such as ultra-thin glass or web with functional layers is highly efficient thanks to the use of roll-to-roll (R2R) technologies. Crucial for plant operators and ultimately for the price is the coating thickness homogeneity and thus also the electrical properties of the applied coatings for a high and above all constant yield without rejects. Until now, the electrical properties of the coating could only be determined and analysed at defined measuring points. Within the joint project KODOS – Fabricated Thin Glass Composite for Optoelectronic Systems (funding reference 13N14607), funded by the German Federal Ministry of Education and Research, an integrable solution for in-line process monitoring and mapping of process parameters was developed with the project partner SURAGUS GmbH at Fraunhofer FEP in Dresden, Germany.
