The company manufactures single-junction perovskite modules for indoor and outdoor light harvesting. According to RadianX, its thin-film modules feature an absorber layer under 1 µm thick deposited on glass or flexible films via low-temperature coating pv-magazine.compv-magazine.compv-magazine.comOpen source ↗. The firm reported certified conversion efficiencies of 22.33% on a 1.2 × 0.6 m form factor and 24.24% on a 300 × 300 mm aperture pv-magazine.compv-magazine.compv-magazine.comOpen source ↗. Under 500 lux indoor illumination, the devices demonstrate a power density of 50 µW/cm² and an indoor conversion efficiency of 38%.
Module portfolio and structural dimensions
RadianX offers modules with thicknesses starting at 0.7 mm, enabling integration into low-power Internet of Things devices and wearable hardware pv-magazine.compv-magazine.compv-magazine.comOpen source ↗. The commercial lineup includes rigid glass AlphaGlass units and semitransparent AlphaVis modules, alongside flexible AlphaFlex devices under development pv-magazine.compv-magazine.compv-magazine.comOpen source ↗. Tunable bandgap values allow the chemical absorber to match artificial ambient lighting or natural solar spectra depending on the application envelope.
Certification testing and production rollout
Independent testing confirmed module compliance with IEC TS 63163 across all three defined tiers, including Category 3 for sustained outdoor exposure pv-magazine.compv-magazine.compv-magazine.comOpen source ↗. The manufacturer stated that accelerated life testing demonstrates a projected field lifespan exceeding 10 years pv-magazine.compv-magazine.compv-magazine.comOpen source ↗. The automated manufacturing facility will expand the company's output from small-batch prototyping to industrial series fabrication for commercial hardware partners.
