Perovskite and organic solar cells must be manufactured via low-cost, high-throughput methods in order to achieve meaningful penetration into the global energy infrastructure in the coming years. Slot-die coating is an established thin film production method with several decades of history in commercial manufacturing of thin film products such as adhesives, capacitors, and Li-ion batteries. It has been shown to satisfy the manufacturing requirements of thin film PV devices, but has typically seen limited lab-scale adoption. This is due to its origin as an industrial manufacturing method, which has made slot-die processes historically challenging and cost-prohibitive to develop at the lab scale.

Over the past decade, FOM Technologies has miniaturized and optimized slot-die technology towards repeatable, scalable R&D of novel thin film coatings and devices. This short presentation provides an overview FOM Technologies slot-die hardware, as well as the benefits of slot-die technology compared to other lab-scale thin film production techniques in thin film PV development.
