The rapid growth of connected devices is creating an unprecedented demand for small, reliable, and sustainable power sources. While batteries have enabled the first generations of IoT and consumer electronics, they also introduce limitations in maintenance, lifetime, form factor, and environmental impact. As the number of connected devices continues to increase, new approaches to powering electronics are required.
Indoor light represents one of the most abundant and accessible energy sources in homes, offices, retail environments, and industrial buildings. Printed organic solar cells are uniquely positioned to harvest this energy efficiently under low-light conditions while offering advantages in flexibility, weight, manufacturing scalability, and system integration. As a result, indoor energy harvesting is evolving from a niche technology into a practical power source for commercial products.
In this presentation, Thomas Österberg, R&D Director and co-founder of Epishine, will share perspectives from the journey of developing and industrializing printed organic photovoltaics for indoor energy harvesting. The talk will touch on the technology itself, lessons learned in scaling manufacturing, integration into electronic products, and the evolving market landscape. Through selected examples and recent developments, the presentation will highlight how printed organic solar is enabling new approaches to powering connected devices.
