The invention relates to a photovoltaic cell comprising a photovoltaically active semiconductor material, wherein the photovoltaically active semiconductor material is a material of the formula (I), of the formula (II) or of a combination thereof: <?in-line-formulae description="In-line Formulae" end="lead"?>(Zn<SUB>1-x</SUB>Mg<SUB>x</SUB>Te)<SUB>1-y</SUB>(M<SUB>n</SUB>Te<SUB>m</SUB>)<SUB>y </SUB>and (I)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>(ZnTe)<SUB>1-y</SUB>(Me<SUB>a</SUB>M<SUB>b</SUB>)<SUB>y</SUB>, where (II)<?in-line-formulae description="In-line Formulae" end="tail"?> M<SUB>n</SUB>Te<SUB>m </SUB>and Me<SUB>a</SUB>M<SUB>b </SUB>are each a dopant in which M is at least one element selected from the group consisting of Si, Ge, Sn. Pb, Sb and Bi and Me is at least one element selected from the group consisting of mg and Zn, and x=0 to 0.5 y=0.0001 to 0.05 n=1 to 2 m=0.5 to 4 a=1 to 5 and b=1 to 3. |
