Abstract
The invention relates polysilazane-containing coatings for increasing the light permeability of sun-facing covers of solar cells. The coating for surfaces contains at least one polysilazane of formula (1) —(SiRR'R″—NR′″1)n- (1), wherein R′, R″, R′″ are the same or different or represent an optionally substituted alkyl, aryl, vinyl or (trialkoxysilyl)alkyl group, n being an integer and n being chosen in such a manner that the perhydropolysilazane has a number average molecular weight of 150 to 150,000 g/mol, a solvent and a catalyst. The cured coating has a thickness of at least 0.50-10 micrometer, preferably 0.2 to 5 micrometer, especially preferred 0.5 to 1.5 micrometer. It is especially suitable as transmission-promoting coating for use in sun-facing covers of solar cells.
