France-based Dracula Technologies, developing low-light energy-harvesting technology for passive (battery-less) LoRaWAN-based IoT connectivity, has said its new production facility in Valence in southeastern France has passed an audit by US-based Semtech for quality, safety and sustainability, and is ready to roll. The firm said last October the factory, offering 2,500 metre-square of floor space with capacity to produce up to “150 million square centimetres” of organic photovoltaic (OPV) devices per year, will start “high-volume” production in “early 2024”.
