Quantum of Sol is a hands on exhibition that explains the physics of solar cells, and originally appeared as part of the Royal Society Summer Science Exhibition 2009 and has also featured in the Imperial Festival and Science Museum. Three main concepts are explored:

1. semiconductor bandgaps
2. increasing efficiency with multiple junctions
3. increasing efficiency using solar concentrators
