The fast advancement of perovskite and organic photovoltaic (OPV) devices is driving demand for scalable, industrially viable material solutions. In this presentation, we will show our company’s capabilities in roll-to-roll processed functional vacuum coatings tailored for next-generation solar cell architectures.
Over the last couple of years, we developed flexible, customer-specific electrode layers on polymer substrates with high conductivity and transmittance higher than 80 %. They were designed to serve as high-performance base substrate for flexible perovskite and OPV devices. Our approach enables precise tuning of electrical, optical, and mechanical properties to meet application-specific requirements, supporting both prototyping and large-scale manufacturing.
In addition, we demonstrate recent progress in the fabrication of optically functionalized layers, including color-tunable coatings that enable aesthetic integration of photovoltaic devices without significantly compromising efficiency. Such solutions are particularly relevant for building-integrated photovoltaics (BIPV) and consumer-facing applications with a high angle-stable color impression.
The presentation highlights selected case studies and development projects from recent years, illustrating how our roll-to-roll vacuum coating technologies contribute to improved device performance, enhanced design flexibility, and industrial scalability.
By bridging material innovation with production-ready processes, we aim to support start-ups, research institutions and universities as well as industry in accelerating the commercialization of emerging photovoltaic technologies.
