The Fundamental Limit of Light Trapping and Solar Cells

Abstract:
What Yu and co show is that by designing the layers in a way that traps light effectively, it is possible to beat the old limit by a substantial margin.

They study, in particular, a patterned cell designed to trap light on the surface and calculate that this can enhance absorption by 12*4*n^2, a significant improvement.

That's important because it places a new fundamental limit on the amount of light that can trapped in a nanophotonic cell.
