Another approach to achieve light trapping in silicon solar cells is the use of reflective external light-trapping structures with length scales larger than the involved wavelengths. Such structures can be modeled employing geometrical optics.
This review paper provides an overview of the physics involved in light trapping in solar cells with special focus on crystalline silicon. The Lambertian (4 n2) limit was derived, and it was explained how this limit can only be overcome through modification of the LDOS within the absorber or within the surrounding air.
For thin film organic solar cells, light trapping schemes need to be modified due to the low refractive index of the substrate, or practical difficulties of employing large textured structures, and also the fundamentally different optical behavior of light in thin films.
The principle of light trapping is to couple the guided whispering gallery modes (WGMs) in the spheres to the specific modes of the solar cell, which in turn increases the solar cell efficiency [ 59 ]. Simulation results show that the performance of a 100-nm-thick GaAs solar cell can be 11% better by optimizing the sphere size and spacing.
Given the fact that theoretical calculations predict remarkable effects of various structures for light trapping in organic thin film solar cells, but the experimental realization is left way behind, it can be foreseen that light trapping for organic solar cells will still be an active field in coming years.
Minimizing optical losses due to insufficient absorption in the thin organic active layer requires novel designs of light trapping schemes. In the article, we reviewed state of the art light trapping techniques for organic solar cells.
