Abstract
Antimony sulfoselenide Sb2(S, Se)3 is a promising material for thin-film solar cells due to its simple elemental composition, low toxicity, high absorption coefficients and tunable bandgap. In this work, we fabricated Sb2(S, Se)3 thin-film solar cells employing hydrothermal approach followed by post-deposition annealing at 350 °C. After that, we screened different organic hole transport layers (HTLs) like Spiro-OMeTAD, P3CT, PTAA, and PEDOT:PSS to evaluate their impact on the photovoltaic (PV) performance of Sb2(S, Se)3 based solar cells. We found that the power conversion efficiency (PCE) is significantly higher using Spiro-OMeTAD as compared to other counterparts.
