## Key points

- RadianX raised $5 million to scale its indoor-light solar technology.
- A manufacturing partner is adding $4 million for a production line.
- The company targets devices such as e-readers and factory sensors.

## Summary

RadianX says its perovskite solar material could help some portable and connected devices run for far longer, potentially without routine charging or battery replacement. The company’s approach targets indoor light, which it says the material harvests twice as effectively as existing solar panels, and could make devices such as e-readers and factory sensors more practical to power.

RadianX raised $5 million in seed funding, led by SOSV and Twynam, and Pacific Union Technology Precision Manufacturing is contributing a further $4 million to build a dedicated production line. The company says a 1.2 by 0.6 metre panel achieves 22.33% light-harvesting efficiency, and that its panels meet an industry durability standard. Perovskites can be less durable and more expensive than silicon, while RadianX is developing tailored power electronics and plans to sell packaged systems to device makers.
