Patent ID: 8563129

Claim:
A method for producing a transparent reflection reducing light-side covering of solar cells on a transparent substrate, for producing insolation-side coverings of solar cells comprising the step of applying a polysilazane-containing solution comprising at least one polysilazane having the following formula —(SiR′R″—NR′″) n — (1) where R′, R″, R′″ are identical or different and stand independently of one another for hydrogen or an optionally substituted alkyl, aryl, vinyl or (trialkoxysilyl}alkyl radical, n being an integer and n being selected so that the polysilazane has a number-average molecular weight of from 150 to 150,000 g/mol, and optionally a solvent, a catalyst or a combination thereof and one or more co-binders, onto a substrate to form a coating and the coating is subsequently ceramized either by the effect of temperature coupled with VUV radiation having wavelength portions <230 nm or UV radiation having wavelength portions between 230 and 300 nm.
