Solar-powered consumer electronics have long promised less reliance on chargers and replaceable batteries. However, as devices become more energy-intensive, conventional small solar cells often struggle to generate enough power within limited space.
US startup RadianX is developing perovskite-based solar panels designed to address this challenge by generating more power from compact surfaces. Co-founder and CEO Vivian Qu identified power density as a key advantage of the material, telling TechCrunch that perovskites can capture substantial amounts of energy without requiring large panels.

According to the company, one of its panels, measuring 1.2 metres by 0.6 metres, achieved a light-harvesting efficiency of 22.33%, which RadianX describes as a record. The panels can be as thin as 0.7 millimetres and adapted to different product dimensions, giving manufacturers greater flexibility when integrating solar technology into electronic devices.
Overcoming The Challenges Of Perovskite Solar
Despite their potential, perovskite materials still face commercialisation challenges. They remain more expensive than conventional silicon-based solar panels, while long-term durability has historically been a concern.
RadianX says its technology has met a key industry durability standard. The company is initially targeting indoor applications, where panels generally face less wear than outdoor installations.
Power electronics present another challenge. Most existing systems are designed for silicon-based cells, which behave differently under light. RadianX is therefore developing specialised electronics to match its panels and improve overall energy capture.
$9 Million To Support Manufacturing
RadianX recently secured $5 million in seed funding led by SOSV and Twynam, with participation from One Small Planet, Sachsen Ventures, Avila VC, California Innovation Fund, quantumEDGE, Riceberg Ventures and Alumni Ventures.
Pacific Union Technology Precision Manufacturing is contributing an additional $4 million in non-dilutive investment to establish a dedicated production line. The funding is intended to help the startup move from technology development towards commercial-scale manufacturing.
For hardware companies, achieving consistent production volumes is a critical step in turning laboratory performance into products that manufacturers can integrate into their devices.
Targeting E-Readers And Industrial Sensors
Rather than supplying standalone solar panels, RadianX plans to offer manufacturers an integrated power solution combining its material with the electronics required to operate it. This approach could simplify adoption by reducing the need for device makers to redesign their power systems around a new component.
Potential applications include e-readers, factory sensors and other low-power electronics. The technology could help devices operate for longer without conventional charging and reduce the need to replace batteries in connected equipment.
However, its commercial success will depend on whether RadianX can bring costs down, demonstrate long-term reliability and scale production to meet manufacturers’ requirements.
