Earth-Abundant Orthorhombic BaCu₂Sn(Se_xS_1–x)₄ (x ≈ 0.83) Thin Film for Solar Energy Conversion

Exploiting renewable solar energy in terms of solar-driven water splitting and photovoltaic devices provides clean and efficient paths to overcome diminishing fossil fuel resources and the greenhouse effect. Here, a state-of-the-art earth-abundant BaCu2Sn(Se0.83S0.17)4 (BCTSSe) thin film has been presented as a promising top-cell absorber in tandem photoelectrochemical water splitting and photovoltaic conversion devices. Our BCTSSe thin film...
