RadianX, a perovskite solar module manufacturer formerly known as California Perovskite Technology, has raised $9 million in combined venture and project financing to scale production of its certified perovskite solar modules.

SOSV and Twynam co-led the seed funding round, with participation from One Small Planet, Sahsen Ventures, Avila VC, California Innovation Fund, quantumEDGE, Riceberg Ventures, and Alumni Ventures.

Separately, Pacific Union Technology Precision Manufacturing, a publicly listed precision components manufacturer, is partnering with RadianX to fund a dedicated production line for commercial volume manufacturing of the company’s modules.

The announcement did not disclose the investment amount for the production line or provide details about its planned manufacturing capacity or location.

RadianX develops perovskite solar modules for applications including sensors, wearables, connected devices, and Physical AI. The modules are designed for applications in low-light and indoor conditions.

According to RadianX, its modules can generate power under these conditions, allowing device manufacturers to extend device runtime, use smaller batteries, or reduce routine battery replacement in some applications. The modules are 0.7 mm thick and can be manufactured in custom sizes and output voltages for integration into product surfaces. RadianX said it is initially focusing on hardware applications and is integrating its modules with device manufacturers.

“Perovskite is a nanomaterial that doesn’t depend on the silicon supply chain. It is carbon-light, needs no rare materials, and can be manufactured from start to finish in a single facility, which means it can be made almost anywhere,” said Vivian Qu, Co-founder and Chief Executive Officer of RadianX. “By building our first automated 6MW production line, we are creating a blueprint we can replicate at a larger scale anywhere in the world.”

The company said its modules have received TÜV certification under all three categories of International Electrotechnical Commission Technical Specification 63163, which covers photovoltaic modules used in consumer products. The certification includes Category 3 for products with high outdoor exposure.

Following the initial financing, Gary Chen, former CEO of Sunspark, a 250 MW solar producer based in Riverside, California, joined RadianX as vice president of manufacturing and product.

In November 2026, Noak, a start-up focused on perovskite-silicon tandem solutions, raised €5 million ($5.57 million) in seed funding to scale and industrialize its technology. The funding comes as Noak prepares to move its perovskite-silicon tandem technology from research and development toward larger-scale manufacturing.

Global VC funding for the solar sector in the first nine months of 2026 came to $2 billion in 60 deals, a 31% decrease YoY compared to $2.9 billion raised in 55 deals in 9M 2025, according to Mercom’s 9M and Q3 2026 Solar Funding and M&A report. A total of 192 VC investors have participated in solar funding in 9M 2026.
