<p>A method of making a crystalline film includes providing a film comprising seed grains of a selected crystallographic surface orientation on a substrate; irradiating the film using a pulsed light source to provide pulsed melting of the film under conditions that provide a mixed liquid/solid phase and allowing the mixed solid/liquid phase to solidify under conditions that provide a textured polycrystalline layer having the selected surface orientation. One or more irradiation treatments may be used. The film is suitable for use in solar cells.</p>
