Designing enhanced two-terminal tandem photovoltaic devices with AgSb2(SxSe1−x)3 absorbers
Integrating silver (Ag) into antimony sulfide selenide Sb(SxSe1−x)3 thin films has recently highlighted their potential as efficient light-absorbing layers in thin-film solar cells. In this work, we have designed and analyzed two-terminal monolithic tandem solar cells with AgSb(SxSe1−x)3 and Sb2S3. The novel tandem device is configured with a AgSb(SxSe1−x)3 bottom subcell with and a top subcell with a Sb2Se3 photovoltaic device with different bandgaps, enabling the selective absorption of targeted photon energy. The upper absorber layer's thickness is carefully calibrated according to the sulfur concentration optimized at xsulfur = 0.2 of the AgSb(SxSe1−x)3 layer to enhance the performance. The bandgap energies for the AgSb(S0.2Se0.8)3 bottom and the Sb2Se3 top subcells are optimized at 1.19 eV and 1.7 eV, respectively. After employing spectral filtering and current matching methodologies, tandem devices demonstrate open-circuit voltage (Voc) of 1.63 V, short-circuit current density (Jsc) of 17.04 mA/cm2, and fill factor (FF) of 62.94 %. These tandem devices could be promising candidates for future photovoltaic devices. The power conversion efficiency is 17.48 %, which shows a promising candidate for high-performing tandem solar cells.
