The invention relates to a process for coating substrates, in particular solar cells. In previous processes, disadvantageously, only strongly alkaline solutions and only nanoparticles could be employed. It is proposed that the substrate in a vessel is charged with a suspension of materials of high refractive index. After the particles have settled out of the suspension, the coated substrate is taken out of the dispersion and dried. The resultant layer can be used as a reflecting layer. One advantage of the reflecting layer is the high refractive index, since the proposed process does not require any additives or binders. A further advantage of this process is the possibility that the same is combinable with other light traps (such as, for instance, plasmonic nanoparticles or other diffraction structures). |
