As the global demand for sustainable energy continues to rise, hybrid and organic photovoltaics (PV) are emerging as transformative solutions.

These technologies offer unique advantages, such as lightweight designs, flexibility, and the ability to be manufactured using cost-effective and scalable processes. Such qualities make them well-suited for diverse applications ranging from wearable devices to building-integrated photovoltaics.

Coatema Coating Machinery is at the forefront of this evolution, bridging the gap between laboratory innovations and industrial-scale roll-to-roll (R2R) production.

This presentation will explore Coatema’s "lab-to-fab" approach, highlighting contributions to advancing PV manufacturing worldwide.

Key focus areas will include an overview of Coatema’s PV machinery deployed globally and insights into the systems that enable efficient, large-scale production.

We will provide a breakdown of essential machine components while addressing the challenges inherent in such complex production systems, to guarantee a stable and reproducible process.

Particular attention will be given to in-line monitoring technologies, which are critical for ensuring product quality during production. These include real-time measurement of coating thickness, sheet resistance, contamination, and defect detection.

Finally, we will provide an outlook on future trends in PV manufacturing.
