concentration in the starting solution, to 4.0 at% also modifies the surface morphology of the films as
triangular shaped laminar structures of about 400 nm height and 10 nm thicknesses were formed at the
surface. It has been found that this triangular surface morphology is an efficient light trapping structure
which is useful for silicon thin film solar cells
