Abstract:
1. 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 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.
