At the heart of any panel is a PV cell, protected by a layer of glass. Sunlight passes through the glass and into the cell where it produces electricity.
Sunlight includes all visible colours plus radiation such as Ultraviolet. A common PV cell works best converting red light into electricity, but is much less effective at converting blue-green light, where the sun’s energy is strongest.
Lambda is designing an active coating to be applied to PV glass.
As blue or green light passes through it will be converted to red and the electrical output will increase.
After just 18 months development Lambda has obtained a prototype yielding a 2-4 % increase in electrical power output. Academic research indicates that a 10% increase is feasible.
Lambda is focused on achieving 5% increase in solar performance, creating advanced materials that are non-toxic, economical and durable.
Benefits of Lambda’s active coating:
Electrical power output of panel increases by up to 10%
Panel temperature reduces due to greater efficiency
Harmful radiation prevented from damaging the PV cell
Improved lifetime, useful for PV application in desert conditions
The Lambda team are developing our advanced materials at the world class Cambridge Nanoscience and Graphene Centres.
