UVC light is the safest, quickest and most effective way to kill disease-causing bacteria and viruses. UVC LEDs are a promising technology which can make chemical-free disinfection possible thanks to their efficiency, long-lasting and compact design. Despite their potential, they remain a niche solution because they face key bottlenecks which prevent them from having a good enough cost-performance (defined as euro/watt) for a consumer market. CrayoNano has developed a completely new UVC LED called SteriLED which will reach these cost-performance targets for the first time, backed by a growing portfolio of market and industry players. We have achieved what leading LED manufacturers have not thanks to our radical new processing technique protected by over 14 patent families. The core technology of SteriLED are core nanowires of the semiconductor AlGaN grown on a substrate of a promising new material, graphene. Thanks to the properties of these two nanomaterials, SteriLED emits 3X more light, has a 3X longer lifetime at one fourth of the costs of standard UVC LEDs. Our strategy to bring SteriLED quickly to the market at the beginning of 2022 is to manufacture them for sales to the OEMs of point of use (POU) water purification devices. SteriLED fits seamlessly into these devices to treat water at the point of consumption to transform them into the most practical, dependable, potent and inexpensive systems on the market. The first successes of SteriLED will be only a stepping stone for its rapid improvement of its cost-performance reduction and its development for new applications from high volume purification systems for water, surface and air disinfection, eliminating the need for thousands of toxic chemicals.
