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...
