Abstract
We present amorphous silicon solar cells on random and periodic back reflector geometries. 1D gratings offer an intuitive understanding of the light trapping process by excitation of guided modes. Using the same period and similar shape, better performance is observed on 2D gratings due to a higher number of resonances.
