SnS2 nanoparticles were synthesized through a simple wet chemical process at room temperature. The SnS2 nanoparticles were approximately spherical in shape and had diameter about 3-4 nm. SnS2-sensitized TiO2 electrodes were fabricated by the immersion of chemically modified TiO2 to well-dispersed SnS2 solution for 72 h (i.e., self-assembly method.) SnS2-sensitized TiO2 electrodes were applied in quantum dot-sensitized solar cells (QDSSCs). Under AM1.5 irradiation with 100 mW/cm2 light intensity (at 1 sun), the short-circuit current density (J(sc)), the open-circuit voltage (V(oc)), the fill factor (FF), and the energy conversion efficiency (eta) were 0.47 mA/cm2, 0.29 V, 0.58 and 0.081%, respectively.
通过简单的室温湿化学法合成了二硫化锡纳米颗粒。二硫化锡纳米颗粒形状近似球形，直径约为3 - 4纳米。通过将化学修饰的二氧化钛浸入充分分散的二硫化锡溶液中72小时（即自组装法）制备了二硫化锡敏化的二氧化钛电极。二硫化锡敏化的二氧化钛电极应用于量子点敏化太阳能电池（QDSSCs）。在100 mW/cm²光强（1个太阳）的AM1.5辐照下，短路电流密度（J(sc)）、开路电压（V(oc)）、填充因子（FF）和能量转换效率（eta）分别为0.47 mA/cm²、0.29 V、0.58和0.081%。
