Method for forming a monodisperse granular film

Abstract

The method for forming the monodisperse granular film includes: providing an initial substrate having a first surface and a second surface opposite to the first surface, forming a sacrificial layer, an adhesive layer and a monodisperse granular layer over the first surface, where the monodisperse granular layer includes multiple granules arranged dispersedly over the first surface, the sacrificial layer is between the multiple granules and the initial substrate, the adhesive layer is between adjacent granules of the multiple granules, and the adhesive layer is exposed between adjacent granules on a side of the multiple granules away from the initial substrate, dissolving and removing the initial substrate, and dissolving and removing the sacrificial layer. The embodiments of the present application are at least conducive to reducing the difficulty in forming the monodisperse granular film, and extending application scenarios of the stacked solar cell.
