This work reports a chemical solution sensitization of HgS nanocrystals on mesoporous TiO₂ films for different deposition times. The adsorption of the precursor ions and the surface growth of the crystal were found to be affected during the temporal deposition of the HgS over spin-coated TiO₂ films. The synthesized electrodes were characterized by structural, morphological, wettability, optical, photovoltaic, and electrochemical performances. The results designate the qualitative confirmation of the TiO₂/HgS heterojunction formation, and the combination is explored for the photovoltaic application, which is first of its kind.

用于光电化学研究的二氧化钛（TiO 2）和硫化汞（HgS）异质结的制备

这项工作报告了HgS纳米晶体在中孔TiO ₂膜上化学沉积对不同沉积时间的敏化作用。发现在旋涂的TiO ₂膜上HgS的时间沉积过程中，会影响前体离子的吸附和晶体的表面生长。合成电极具有结构，形态，润湿性，光学，光电和电化学性能。结果表明定性证实了TiO ₂ / HgS异质结的形成，并探索了这种组合在光伏应用中的应用，这是其首次。
