Cambridge Photon Technology

The performance upgrade the solar industry's been waiting for. We’re developing advanced materials to deliver drop-in innovation that breaks through the efficiency limits of solar - no new factories, no new lines, just more power from every panel. As global solar capacity increases by 500+ GW year-on-year, Cambridge Photon Technology (CPT) is here to solve the industry's biggest bottleneck: the performance ceiling of silicon-based photovoltaic technology. Our world-first Photon Multiplier delivers up to 15% more power from every panel - with zero changes to solar panel design and manufacturing processes. This isn't just incremental improvement; it's the only proven drop-in solution capable of pushing solar efficiency above 28%, unlocking billions in value across >1TW of installed PV manufacturing assets worldwide. Our vision extends beyond efficiency gains. CPT offers IP-protected innovation that creates strategic value across the entire supply chain. Founded at the University of Cambridge's Cavendish Laboratory, we're not here to change how solar is made - we're here to change what it can achieve. The future of solar starts here.
