Growth of isolated grains in the mixed phase silicon films was examined by atomic force microscopy. We propose to use the grain shape as a probe for otherwise inaccessible microscopic growth processes. The depression of amorphous silicon surface in the vicinity of the grains was used to estimate the diffusion length of the growth precursors to be (60 ± 30) nm. Grains have approximately conical shape but the slope of the grain boundary evolves in two growth stages (expansion and elongation). During the whole evolution the caps of the grains on the surface keep spherical shape. A possibility of light focussing by the spherical grain caps was suggested. Coincidence of the focussed photogeneration with the high electric field region near the grain tip could lead to solar cells with photogeneration of the carriers spatially separated according to the photon energy.
