Abstract

In tandem thin-film solar cells with a superstrate device structure, the front transparent conductive oxide (TCO) contact needs high transmission and high conductivity for top cells, as well as higher transmission at the near-infrared wavelength region for bottom cells. Unfortunately, conventional TCOs (such as ITO, SnO₂, and ZnO) cannot completely meet these requirements. We developed a high-quality cadmium stannate (Cd ₂SnO₄ or CTO) TCO film, which has transmission of 80%-90% in the region of 400-1300 nm and bulk resistivity of ≈1.8×10 ^-4 Ω cm. In the CdTe/CIS tandem thin-film solar cell, the short-circuit current density (J_sc) loss due to CTO film absorption can be reduced to only 0.6 mA/cm² and ≈1.0 mA/cm² for the top cell and bottom cell, respectively.
