摘　　要：The maximum theoretical power conversion efficiency(PCE)for single-junction solar cells based on the Shockley-Queisser(S-Q)model is 33.7%for an optimal bandgap(Eg)of 1.34 eV under 1-sun illumination[1].Multi-junction(tandem)solar cells present a realistic option for overcoming the S-Q limit and achieving efficiency of>40%due to decreased thermalization loss in tandem configuration[2].Metal halide perovskites,in particular,are the most sought-after materials for tandem solar cells(TSCs),as their bandgap energy can be fine-tuned from 1.2 to 3 eV by simple compositional engineering.Recently,two-junction perovskite tandems with silicon attained an astounding efficiency of 33.9%,surpassing the previous record of PCEs of single-junction perovskite and silicon solar cells,and bolstering investor confidence in perovskite-based tandem technologies[3].
