| 英文摘要 | Antimony selenosulfide (Sb-2(S,Se)(3)), featuring large absorption coefficient, excellent crystal structure stability, benign non-toxic characteristic, outstanding humidity and ultraviolet tolerability, has recently attracted enormous attention and research interest regarding its photoelectric conversion properties. However, the open-circuit voltage (V-oc) for Sb-2(S,Se)(3)-based photovoltaic devices is relatively low, especially for the device with a high power conversion efficiency (eta). Herein, an innovative Se-elemental concentration gradient regulation strategy has been exploited to produce high-quality Sb-2(S,Se)(3) films on TiO2/CdS substrates through a thioacetamide(TA)-synergistic dual-sulfur source hydrothermal-processed method. The Se-elemental gradient distribution produces a favorable energy band structure, which suppresses the energy level barriers for hole transport and enhances the driving force for electron transport in Sb-2(S,Se)(3) film. This facilitates efficient charge transport/separation of photogenerated carriers and boosts significantly the V-oc of Sb-2(S,Se)(3) photovoltaic devices. The champion TA-Sb-2(S,Se)(3) planar heterojunction (PHJ) solar cell displays an considerable eta of 9.28 % accompanied by an exciting V-oc rising to 0.70 V that is currently the highest among Sb-2(S,Se)(3)-based solar cells with efficiencies exceeding 9.0 %. This research is anticipated to contribute to the preparation of high-quality Sb-2(S,Se)(3) thin film and the achievement of efficient inorganic Sb-2(S,Se)(3) PHJ photovoltaic device. |
