Switchable SPD for Smart Windows with Controlled Shading and Solar Energy Harvesting Ability
Benjamin Heiz1,2*, Zhiwen Pan2, Gerhard Lautenschläger3, Lothar Wondraczek1,2

We will present a switchable, ultra-thin suspended particle device for large-area smart window integration 1). The system is based on a fluidic window, manufactured from high-quality rolled glass with an embedded channel structure. Controlled and magnetically switchable immersion of nanoparticles with tailored absorption behaviour enables control of visible and infrared light transmission, both for shading and collection of solar heat.
