Thin-film solar cells are expected to play a significant role in the space industry, building integrated photovoltaic (BIPV), indoor applications, and tandem solar cells, where bifaciality and semitransparency are highly desired. Sb2(S,Se)3 has emerged as a promising new photovoltaic (PV) material for its high absorption coefficient, tunable bandgap, and nontoxic and earth-abundant constituents. However, high-efficiency Sb2(S,Se)3 solar cells exclusively employ monofacial architectures, leaving a considerable gap toward large-scale application in aforementioned fields. Here, a bifacial and semitransparent Sb2(S,Se)3 solar cell and its extended application in tandem solar cells are reported. The transparent conductive oxides (TCOs) and the ultrathin inner n–i–p structure provide high long-wavelength transmittance. Despite the MnS/ITO Schottky junction, power conversion efficiencies (PCEs) of 7.41% and 6.36% are achieved with front and rear illumination, respectively, contributing to a great bifaciality of 0.86. Consequently, the reported device gains great enhancement in PV performance by exploiting albedo of surroundings and shows exceptional capability in absorbing tilt incident light. Moreover, an Sb2(S,Se)3/Si tandem solar cell with a PCE of 11.66% is achieved in preliminary trials. These exciting findings imply that bifacial and semitransparent Sb2(S,Se)3 solar cells possess tremendous potential in practical applications based on their unique characteristics.

用于单结和串联光伏应用的双面和半透明 Sb2(S,Se)3 太阳能电池
薄膜太阳能电池预计将在航天工业、建筑一体化光伏（BIPV）、室内应用和串联太阳能电池等领域发挥重要作用，这些领域都非常需要双面和半透明。Sb 2 (S,Se) 3因其高吸收系数、可调带隙、无毒且地球丰富的成分而成为一种有前途的新型光伏（PV）材料。然而，高效Sb 2 (S,Se) 3太阳能电池仅采用单面结构，距离大规模应用还有相当大的差距。本文报道了一种双面半透明Sb 2 (S,Se) 3太阳能电池及其在串联太阳能电池中的扩展应用。透明导电氧化物 (TCO) 和超薄内部 n-i-p 结构提供高长波长透射率。尽管采用 MnS/ITO 肖特基结，但在前照明和后照明下，功率转换效率 (PCE) 分别达到 7.41% 和 6.36%，从而实现了 0.86 的双面率。因此，所报道的器件通过利用周围环境的反照率大大提高了光伏性能，并显示出吸收倾斜入射光的卓越能力。此外，初步试验还获得了PCE为11.66%的Sb 2 (S,Se) 3 /Si叠层太阳能电池。这些令人兴奋的发现意味着双面半透明Sb 2 (S,Se) 3太阳能电池因其独特的特性在实际应用中具有巨大的潜力。
