Abstract:
1. A photovoltaic cell having a photovoltaically active semiconductor material constituted by a plurality of metals or metal oxides, wherein the photovoltaically active material is selected from the group consisting of (a) a p- or n-doped semiconductor material constituted by a ternary compound of formula (I) with Me=Al, Ti, Zr, V, Nb, Ta, Cr, Mo, W, Mn, Fe, Co, Ni, Cu or Ag, S where S A and S B respectively come from different groups of the periodic table, x, y, z are independent of one another and can take values from 0.01 to 1, and where the proportion by weight of S (b) a mixed oxide of formula (II) with Me=Fe, Cu, V, Mn, Sn, Ti, Mo, or W, n=integer from 1 to 6, a=1 or 2, f=number from 0.2 to 5, k=number from 0.01 to 2,
