Lambda’s active coating boosts PV output by 10%
Diagram of a simple PV cell

Sunlight includes all visible colours plus radiation such as Ultraviolet (UV). A common PV cell works best at converting red light into electricity but is much less effective for UV-green light.

Lambda’s coating added to increase efficiency

Lambda is designing an active coating to be applied to PV glass, either for new-build solar panels or in a retrofit configuration for installation onto existing solar farms.

As UV, blue, or green light passes through the coating, it will be converted to red, and the electrical output will increase.

Lambda will deliver a 10% increase in solar performance. Our own modelling indicates that 15% is feasible.

We are creating advanced materials that are non-toxic, economical and durable.

Our scientific team is developing nanocrystals for solar applications, which use a process called quantum cutting to yield two near-infrared photons for every Ultraviolet (UV) photon that is absorbed. Please see our Technology page for more information.

Benefits of Lambda’s nanocrystals for Solar PV:

  • Electrical output of panel increases by 10% or more
  • Beneficial to modern silicon PV modules
  • PV cell lifetime is extended as harmful UV light is converted into useable electricity

Our commercial strategy is to establish partnerships with the international chemical companies which supply key materials to the solar PV manufacturing sector, primarily polymers (i.e., plastics), pigments and anti-reflective coatings. We already have pilot testing lined up for our retrofit solution, with one of the leading UK solar farm operators.

We are seeking further collaborations with materials companies in the solar and polymer chemistry sectors. If you would like to understand more, are interested in incorporating our nanocrystals into your material, or would consider joining a funded research collaboration, then we’d love to hear from you.

Lambda is seeking strategically aligned investors who can help us accelerate the development and adoption of our technology. If you would like to discuss then please contact us at

The Lambda team are developing our advanced materials at the world class Cambridge Nanoscience and Graphene Centres.
