[How we decide](https://millionrounds.com/methodology) ## About Cambridge Photon Technology Cambridge Photon Technology (CPT) is a deep-tech startup founded in 2019, emerging from the University of Cambridge. The company specializes in advanced materials designed to enhance the efficiency of silicon solar panels by 15-20% through its patented photon multiplication technology. CPT's innovative photon multiplier film converts high-energy photons, which are typically lost as heat, into lower-energy photons that can be absorbed by solar cells, thereby increasing power output without changing existing manufacturing processes. Headquartered in Cambridge, England, CPT focuses on commercialization, research and development, and pilot deployments, aiming for market entry by 2028. The company has secured over £1.6 million in pre-Series A funding and holds four key patents licensed from the university. CPT collaborates with academic and industry partners for material development and testing, contributing to projects like PILATUS and receiving recognition such as The Spinoff Prize 2021. ## What company datasets say Cambridge Photon Technology raised Funding, as reported Reported in all **1.5M** in the source's currency Rounds **1** Last round **Seed** Last round size **1.2M** Last round date **Jan 2020** Investors listed **5** ## Funding filed with regulators Cambridge Photon Technology filed 8 raises, $3.6M in all.
