Abstract :
The light scattering effect by rough surface of amorphous silicon was examined by several methods. We use the newly adopted Integral equation method and compare it with the first order approximation or high frequency approximation (geometric optics solution) of Kirchhoff method. The surface of amorphous silicon was assumed as Gaussian rough surface. The enhancement of light absorption by surface scattering can be predicted more accurately by the method suggested here.
