To replace the conventional chemical bath deposition method, which is time‐consuming and has a high impurity level, a chemical single‐step deposition process employing a S/Sb ratio‐controlled SbCl₃‐thiourea complex solution is introduced to load Sb₂S₃ into a mesoporous TiO₂ electrode. This technique enables the fabrication of efficient and reproducible Sb₂S₃‐sensitzed inorganic–organic heterojunction hybrid solar cells with hole‐conducting conjugated polymers. The most efficient cell exhibits a short‐circuit current density of 16.1 mA cm⁻², an open circuit voltage of 595.5 mV, and a fill factor of 66.5%, yielding a power conversion efficiency of ≈6.4% at standard AM1.5G condition (100 mW cm⁻²).

通过使用S / Sb比率控制的SbCl3-硫脲复合物溶液一步一步沉积Sb2S3来实现高效的Sb2S3敏化太阳能电池

为了取代费时且杂质含量高的常规化学浴沉积方法，引入了采用S / Sb比率控制的SbCl _3-硫脲复合溶液的化学单步沉积工艺来加载Sb ₂ S ₃进入介孔TiO ₂电极。这项技术可以制造具有空穴传导共轭聚合物的高效且可复制的Sb ₂ S ₃敏化的无机-有机异质结混合太阳能电池。最高效的电池具有16.1 mA cm ^-2的短路电流密度，开路电压为595.5 mV，填充系数为66.5％，在标准AM1.5G条件下（100 mW cm ^-2）产生的功率转换效率约为6.4％。
