The pursuit of more efficient buildings is driving digitalization, leading to a rapidly growing need for connected sensors. These sensors typically rely on batteries, necessitating costly maintenance to replace them every few years and contributing to a significant environmental impact.

By harnessing ambient energy, the lifespan of batteries can be extended, and in many cases, batteries may become unnecessary. Circumventing the issues with batteries will enable much easier deployment of distributed sensing, facilitating data collection that, in turn, yields a more energy-efficient society. Light is a primary source of ambient energy in buildings, and organic solar cells can be tuned to harvest that light energy with high efficiency. Examples of applications for connected devices suitable for light energy harvesting include electronic shelf labels, asset tracking labels, and consumer electronics such as remote controls.

Epishine, an innovative Swedish company, has developed a scalable manufacturing process for organic solar cells using roll-to-roll printing and lamination technologies. This technology puts Epishine in a favorable position to address the increasing demand for high-performance indoor solar cells. In this presentation, I will provide an overview of Epishine's technology and manufacturing process, as well as present some of Epishine’s internal research efforts based on our unique approach to producing OPV [1]
