Quasi-solid-state dye-sensitized solar cell was fabricated by sandwiched polymer electrolyte containing liquid electrolytes between the dye-sensitized TiO2 electrode and a Pt electrode. The influence of hydrochloric acid treatment of TiO2 photoelectrode on the photoelectronic performance was investigated. Quasi-solid-state dye-sensitized solar cell showed better photoelectronic performance when the TiO2 electrode was treated with hydrochloric acid than that without treatment. The short-circuit current density (J(sc)), the open-circuit voltage (V(oc)), and a conversion efficiency obtained for an incident light intensity of 100 mW m(-2) were 6.49 mA cm(-2), 0.76 V and 4.1%, respectively. It was found that the hydrochloric acid treatment of TiO2 electrode increased the short-circuit current density and cell efficiency.
通过将含有液体电解质的聚合物电解质夹在染料敏化的TiO₂电极和Pt电极之间制备了准固态染料敏化太阳能电池。研究了TiO₂光电极的盐酸处理对光电性能的影响。当TiO₂电极用盐酸处理时，准固态染料敏化太阳能电池表现出比未处理时更好的光电性能。对于100 mW m⁻²的入射光强度，短路电流密度（J(sc)）、开路电压（V(oc)）和转换效率分别为6.49 mA cm⁻²、0.76 V和4.1%。发现TiO₂电极的盐酸处理提高了短路电流密度和电池效率。
