CPTI is now RadianX
Perovskite solar that turns indoor and outdoor light into power, so devices run longer on smaller batteries or none at all.
RadianX turns ambient light into usable energy at the point of use. Our low-light PV platform enables products to generate more of the power they need—reducing batteries, eliminating battery swaps, and removing maintenance from the equation.
Sensors, connectivity, and on-device intelligence are moving into more products and more places. But battery energy density and access to wired or grid power are not keeping pace with the demands of distributed edge hardware.
RadianX harvests ambient light where devices operate, creating local power at the point of use. The result: battery-free products, fewer battery swaps, less wiring, and maintenance-free operation.
Dormant surfaces now become power architecture.

AlphaGlass by RadianX integrates the materials, electronics, and manufacturing required to turn full-spectrum light into application-ready energy.
Tunable absorber + interface layers for different light environments.
Protection engineered to operating environment and product life.
Custom geometry, substrate, size, and mechanical configuration.
Integrated power management + MPPT.
Transferable process IP designed for scalable production.
The best energy architecture starts with the application.
RadianX works directly with engineering and product teams to define the right materials, geometry, voltage, electronics, encapsulation, and manufacturing approach.
Application-specific samples and engineering support.
Performance, reliability, and integration testing.
A clear path from design qualification to recurring production.
Our engineers work with yours from the first sample through production.
Intelligence is moving into sensors, wearables and robots. We turn indoor and outdoor light into power, helping these devices run longer and deploy with fewer power constraints.
Power sensors, cameras, doorbells, trackers and e-paper from ambient light. Suitable low-power designs can run without a battery or use one designed to last the device’s life.
Extend runtime for wearables, AI glasses and rugged handhelds with power generated at the device’s surface.
Support standby power, help protect batteries from deep discharge and add supplemental charging outdoors.
Traditional solar was designed for roofs and fields. AlphaGlass
by RadianX is designed for surfaces, products and environments where rigid silicon was never practical. Built for changing light, our perovskite platforms harvest energy indoors and outdoors.
