The present invention provides a thick-film paste for printing the front side of a solar cell device having one or more insulating layers. The thick-film paste comprises an electrically conductive metal and a lead-tellurium-boron-oxide dispersed in an organic medium. L'invention concerne une pâte pour film épais servant à imprimer la face avant d'un dispositif à cellules solaires comportant une ou plusieurs couches isolantes. La pâte pour film épais comporte un métal électroconducteur et un oxyde de plomb-tellure-bore dispersé dans un milieu organique.
