Addressing the critical challenge of increasing the efficiency of solar panels is essential to meet growing energy demands sustainably.
To tackle this issue, Cambridge Photon Technology (CPT) has developed innovative photon multiplier materials that enhance the performance of existing silicon solar panels.
These advanced materials work by splitting and increasing the number of infrared photons that reach the solar panels, thereby harvesting more solar energy. This technology seamlessly integrates into existing photovoltaic modules without requiring changes to the manufacturing process, allowing for quick and scalable improvements.
By boosting the efficiency of silicon solar panels by up to 15%, CPT’s solution not only increases energy output but also provides a more environmentally friendly and cost-effective option for solar power generation.

Taking solar panel performance to the next level
Cambridge Photon Technology originated from groundbreaking research at the University of Cambridge, founded by Dr Claudio Marinelli, Professor Hugo Bronstein, and Professor Akshay Rao. The company has achieved key milestones, including demonstrating its photon multiplier technology and scaling production processes. CPT collaborates with academic and industry partners, such as the University of Cambridge and various photovoltaic manufacturers, to advance and validate their innovative materials in real-world applications.
CPT has received significant funding, including grants from Innovate UK and the Energy Entrepreneurs Fund, as well as investments from Cambridge Enterprise Ventures and other key investors. These funds have accelerated their research and development efforts. Currently, CPT is focused on refining its photon multiplier technology, scaling up production, and exploring new markets. Their future plans include further enhancing solar panel efficiency and contributing to global sustainable energy solutions.
