RadianX Secures $9M to Commercialize Perovskite Solar and Kill the IoT Battery

REDWOOD CITY, Calif. – November 05, 2026 – For the better part of a decade, perovskite solar technology has been the clean energy sector's most tantalizing mirage. In the laboratory, it promised extraordinary efficiency, ultra-thin flexibility, and the ability to generate power from mere ambient light. Yet, the moment these nanomaterials were exposed to the harsh realities of commercial manufacturing and outdoor elements, they degraded rapidly. Today, that narrative officially shifts.

RadianX, formerly operating as California Perovskite Technology, Inc., has announced a $9 million combined venture and project financing round to scale production of its certified perovskite solar modules. Co-led by SOSV and Twynam, with participation from One Small Planet, Sahsen Ventures, and others, the seed round signals a critical transition for the industry. More importantly, RadianX has partnered with Pacific Union Technology Precision Manufacturing (PUT)—a publicly listed precision components manufacturer—to fund and build a dedicated 6MW automated production line.

For industrial strategists and asset allocators watching the 2026 economic landscape, this is not just another early-stage hardware funding announcement. It is a blueprint for the decentralized future of energy harvesting, targeting a multi-billion-dollar bottleneck in the global Internet of Things (IoT) hardware market: the routine replacement of batteries.

Crossing the 'Valley of Death'

The commercialization of perovskite has historically been paralyzed by the "quad-lemma" of efficiency, stability, scalability, and sustainability. Lab records rarely survived the jump to full-sized modules, the materials degraded quickly under moisture or heat, and the inclusion of lead raised severe environmental red flags.

RadianX has systematically dismantled these hurdles. The company's modules are among the world's first to be certified by TÜV across all three categories of the IEC TS 63163 specification for consumer photovoltaic modules. Crucially, this includes Category 3, the rigorous rating for products with high outdoor exposure. This certification proves that the encapsulation and material engineering have finally bridged the gap between fragile lab curiosity and durable commercial hardware.

"Perovskites have been one of the hardest problems in solar, because lab records have rarely held up as stable, manufacturable products," said Po Bronson, General Partner at SOSV and Managing Director at SOSV SF. "We invested in RadianX because we have conviction in both the technology and the team, which already has certified modules in customers' hands."

Beyond durability, RadianX has solved the scalability and toxicity equations. The company holds a certified 22.33% efficiency record on a commercial-scale 1.2-by-0.6-meter module format. Furthermore, the modules have passed stringent lead-release testing under the European Union's REACH regulation and comply with RoHS standards. By proving that lead leakage can be effectively contained—falling below the thresholds of conventional silicon panels with lead solder—RadianX has cleared the primary regulatory roadblock preventing mass deployment in consumer electronics.

Powering the Battery-Free Edge

The immediate commercial target for RadianX is not utility-scale solar farms, but the rapidly expanding "edge energy" market. The global ambient IoT market is projected to reach nearly $35.8 billion by 2035, driven by an insatiable demand for sensors, wearables, connected devices, and Physical AI. Currently, this ecosystem is tethered to a massive, unsustainable reliance on disposable batteries.

Traditional silicon solar cells fail in this arena; they are designed for direct sunlight and suffer catastrophic efficiency drops in low or indoor light. RadianX's modules, which are as thin as 0.7mm, thrive in indoor, outdoor, and diffuse light environments, delivering up to 250 W/m² with minimal added mass. This allows device makers to integrate the modules directly into the surfaces of existing products, drastically reducing battery size or eliminating the need for routine battery replacement entirely.

"Most connected devices still depend on a battery that someone has to replace," said Josh Douglas, Co-founder and Chief Operating Officer of RadianX. "Our job is to turn that light those devices already receive into power, to drive increased uptime and even reduce or eliminate the battery."

The commercial traction is already materializing. RadianX has been selected for the 2026 Amazon Devices Climate Tech Accelerator, run by Plug and Play, positioning the technology for potential integration into one of the world's largest consumer electronics ecosystems. Simultaneously, the company is collaborating with NGK Corporation, pairing RadianX modules with NGK's high-performance EnerCera batteries to power wireless asset trackers. In the logistics and supply chain sectors, where tracking millions of assets is hampered by the labor costs of battery maintenance, a self-sustaining tracking node is a holy grail.

While RadianX faces competition from organic photovoltaics (OPV) and dye-sensitized solar cells (DSSC) developed by companies like Epishine and Dracula Technologies, RadianX's high efficiency and the sheer scale of its upcoming 6MW production line provide a distinct competitive moat in the race to power the battery-free edge.

Bypassing the Silicon Bottleneck

Beyond the immediate applications in IoT, RadianX's manufacturing strategy offers a profound geopolitical advantage. The traditional silicon solar supply chain is highly centralized, energy-intensive, and vulnerable to global trade disruptions. It requires polysilicon refining, ingot casting, wafer slicing, and cell manufacturing, often spread across multiple facilities and international borders.

Perovskite upends this paradigm. "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 larger scale anywhere in the world."

The partnership with Pacific Union Technology Precision Manufacturing is the linchpin of this strategy. Based in Shenzhen, PUT is a heavyweight in high-precision component manufacturing, supplying major brands like Apple and Amazon. By funding and hosting RadianX's dedicated production line, PUT transitions the technology from a venture-backed prototype to a commercially scaled industrial product.

"RadianX has demonstrated world-leading performance and stability metrics across all important categories, and has validated that performance in customer hands. This positions the technology as a key unlock for perovskite applications across all markets," said Tiger Yang, CEO of PUT. "PUT is proud to partner with RadianX, bringing our experience in delivering at scale together with their unique technology to scale capacity and meet RadianX's immediate customer demand."

To execute this manufacturing blueprint, RadianX has brought on Gary Chen as VP of Manufacturing and Product. Chen's transition from his previous role as CEO of Sunspark, a 250MW traditional silicon solar producer, serves as a bellwether for the broader industry. When veteran silicon executives begin migrating to perovskite operations, it signals that the technology's commercial viability is no longer theoretical.

As the 2026 economic landscape continues to be shaped by supply chain resilience and the exponential growth of connected hardware, RadianX is positioning itself at the exact intersection of these macro forces. By conquering the lab-to-market divide, the company is not just offering a new way to power sensors; it is offering a decentralized, silicon-free model for the future of global energy manufacturing.
