摘要：A novelty method has been replenished for getting one kind of photoanode materials for dye-sensitized solar by an ingenious way. Using the ZnTi layered double hydroxide (LDH) as a precursor of photoanode materials, the ZnTi-LDH with different ratios were produced through urea method. Since the thermal treatment of LDH precursor at 500 degrees C, the ZnTi mixed metal oxides (MMO) were easily obtained and then DSSC based on different ratios of ZnTi-MMO were fabricated with two kinds of dyes (C101 and Z907). The different ZnTi cationic ratios and diverse dyes make a big difference on the performance of DSSC. As the amount of Zn2+ increasing, the photocurrent and power conversion efficiency (PCE) of the cells first increase and then decrease. The optimal efficiency under C101 condition gets up to 1.57% at 9:1 cationic ratio of the ZnTi-LDH precursor. The C101 dye exhibits a more impressive performance than the Z907 where the DSSC is equipped with same MMO and other conditions.
