Stable AgBiS2 near-infrared absorbers for thin film tandem photovoltaics

Shiling Dong, Yongjie Wang, Hae-Jun Seok +22

AgBiS2 has rapidly risen in efficiency as single-junction photovoltaics (PVs), but its potential for tandem PVs is unexplored. Herein, we perform optical modeling based on the expe…
