首次报道了以Sb_2 O_3、Se、CS_2和正丁胺的DMF混合溶液为前驱体，在200 °C的低温热解-晶化温度下制备出低硒Sb_2S_xSey（x：y= 3.0：0.2）薄膜。具有FTO/紧凑型TiO 2/Sb 2SxSey/spiro-OMeO 2/Au结构的相应薄膜太阳能电池实现了5.54%的功率转换效率，沿着具有0.56 V的开路电压、16.16 mA cm-2的短路光电流密度和0.61的填充因子。低温制备晶态Sb 2SxSey薄膜为柔性Sb 2SxSey薄膜太阳能电池的组装提供了一条可行的途径。
The low pyrolysis-crystallization temperature of 200 °C was firstly reported to prepare crystalline low-selenium Sb2SxSey(x:y= 3.0:0.2) thin films using the mixture solution of Sb2O3, Se, CS2, andn-butylamine in DMF as a precursor solution. The corresponding thin film solar cells with the architecture of FTO/compact TiO2/Sb2SxSey/spiro-OMeTAD/Au achieved a power conversion efficiency of 5.54%, along with an open-circuit voltage of 0.56 V, a short-circuit photocurrent density of 16.16 mA cm−2and a fill factor of 0.61. The low-temperature preparation process of crystalline Sb2SxSeythin films can provide a feasible approach for assembling the flexible Sb2SxSeythin film solar cells.Graphical abstract
