RadianX raises $9M to develop perovskite solar cells for always-on devices
Key points
- RadianX raised $5M in seed funding and $4M non-dilutive investment.
- The company develops perovskite solar cells.
- New cells are twice as efficient indoors as existing solar panels.
- Funding will establish a commercial production line.
Funding for Perovskite Solar Technology
RadianX, a startup focused on solar energy solutions, recently closed a $5 million seed funding round led by SOSV and Twynam. Additional investors included One Small Planet, Sachsen Ventures, Avila VC, California Innovation Fund, quantumEDGE, Riceberg Ventures, and Alumni Ventures. Concurrently, Pacific Union Technology Precision Manufacturing is providing $4 million in non-dilutive investment to build a dedicated production line for RadianX's technology.
Advancements in Solar Material
RadianX has developed a new type of solar material using perovskites. This material matches the efficiency of existing solar panels outdoors and demonstrates double the efficiency when harvesting light indoors. This indoor efficiency is a key differentiator, allowing devices to operate continuously without needing to be charged from a power outlet.
The company states that its 1.2 meter by 0.6 meter panel achieves 22.33% light harvesting efficiency, which it claims is a record for this type of material.
Applications for Always-On Devices
The enhanced indoor efficiency of RadianX's perovskite solar cells could enable what the company terms "edge energy." This technology could power devices such as e-readers, IoT sensors, robots, and wearables, eliminating the need for frequent recharging or battery replacements. The co-founders, Josh Douglas and Vivian Qu, emphasize the high power density of perovskites as crucial for modern device requirements.
Perovskite Technology Background
While perovskites are not a new discovery, their commercial adoption has been limited due to higher costs and lower durability compared to traditional silicon-based solar panels. However, recent advancements have improved their performance. RadianX's focus on specific applications where durability is less of a concern, such as indoor or contained environments, allows them to leverage the material's power delivery advantages.

Reporting from
RadianX secured $5 million in seed funding and an additional $4 million in non-dilutive investment to develop and commercialize perovskite solar cells. These new solar panels are twice as efficient indoors as traditional panels, enabling portable and edge devices to operate without external charging. The funding will establish a production line for these solar materials.
