Batteries have transformed electronics, giving us powerful phones, tablets, e-readers, and smart watches. But eventually, every battery runs flat.
Maybe not for long. One startup, RadianX, envisions a world in which portable and edge devices can cut the cord for good without running out of power. The key is a better breed of solar panels.
RadianX has developed a new type of solar material from a family known as perovskites. The material is just as good as existing solar panels outdoors, but twice as good at harvesting light indoors.
“We can harvest any kind of photon, whether it’s an outdoor or indoor photon, and keep the device running longer — or running forever,” Josh Douglas, co-founder and COO, told TechCrunch.
The indoor efficiency of RadianX’s tech could be the key to unlocking what the company calls “edge energy.” Think an e-reader that never needs charging or an IoT sensor that never needs a battery swap. But as with any new category, unexpected uses could emerge, including long-runtime robots or wearables that have been held back by limited battery power.
To fund a commercial-volume production line, RadianX recently raised $5 million in a seed round led by SOSV and Twynam, the company exclusively told TechCrunch. Other investors included One Small Planet, Sachsen Ventures, Avila VC, California Innovation Fund, quantumEDGE, Riceberg Ventures, and Alumni Ventures. Alongside the seed money, Pacific Union Technology Precision Manufacturing is pitching in $4 million of non-dilutive investment to build a dedicated production line for the startup.
