	abstract = {The\&nbsp;quasiparticle\&nbsp;band structures and optical properties of ACdTS kesterite are investigated here on the basis of first-principles calculations, including the many-body effects theory, by using the GW plus Bethe-Salpeter equation. There were significant GW-quasiparticle corrections, over 0.9\&nbsp;eV, to the GGA-Kohn-Sham band gap. Our calculations also show that ACdTS kesterite had a small binding energy, exhibited\&nbsp;optical absorption\&nbsp;in the visible region, high minority\&nbsp;carrier mobility, and large diffusion in length, rendering this material a promising candidate for solar cells. Based on these findings, we designed and implemented an ACdTS absorber in a thin-film solar cell (TFSC) structure. The new kesterite solar cell has a high efficiency of 11.6\% with a low deficit in the output voltage. Moreover, a strategic combination between the\&nbsp;particle swarm optimization\&nbsp;approach and the ACdTS TFSC decorated with periodic nanowires is proposed to obtain significantly improved\&nbsp;photovoltaic\&nbsp;characteristics. The optimized design identifies a new pathway for a high conversion efficiency of 14\%, far surpassing that provided by the conventional TFSC kesterite.},
