Abstract

Sm³⁺-doped barium borate glasses are investigated for their potential as a superstrate for CdTe solar cells. The influence of the Sm³⁺ conversion efficiency and the Sm₂O₃ doping level on the short circuit current density of a CdTe solar cell is analyzed. CdTe solar cells with CdS layer thicknesses of 45 and 300 nm are evaluated. A 3.2 mm thick, 2 mol% Sm₂O₃- doped glass superstrate enables a relative increase in the short circuit current density of approximately 1.4% and 2.9% for a 45 and 300 nm CdS buffer layer, respectively, assuming 100% Sm³⁺ conversion efficiency.
