在染料敏化太阳能电池(DSCs)中，硬脂酸作为共吸附剂，具有低的偶极矩和高的溶解度，减缓了染料在TiO2层上的竞争锚定过程中的吸附速度，从而增加了强结合染料在TiO2层上的含量。这使得J(SC)和DSC的功率转换效率都提高了约25%，即使染料覆盖率要低得多。
Stearic acid as a coadsorbent, which has a low dipole moment and high solubility, retarded the rate of dye adsorption during the competitive anchoring process on the TiO(2) layer in dye-sensitized solar cells (DSCs), thereby increasing the content of strongly bound dye on the TiO(2) surface. This resulted in an approximately 25% improvement in both J(SC) and the power conversion efficiency of the DSCs, even for much lower dye coverage.
