We report a quantum dot sensitized solar cell (QDSSC) with a thioglycolic acid (TGA) capped CdSe quantum dot (QD) sensitized ZnO nanorod photoanode. As revealed by UV-Vis absorption spectrum and transmission electron microscopy, the quantum dots can be effectively adsorbed onto ZnO nanorods. By studying the emission decay, the quenching of the CdSe QDs by ZnO nanorod was verified, and an electron transfer (from QD to ZnO) rate constant of 1 x 10(8) s(-1) was obtained. The efficiency of the as-prepared QDSSC was 0.66% and an incident power conversion efficiency of 22% at 400 nm was achieved.
我们报道了一种量子点敏化太阳能电池（QDSSC），其具有用巯基乙酸（TGA）包覆的CdSe量子点（QD）敏化的ZnO纳米棒光阳极。紫外-可见吸收光谱和透射电子显微镜显示，量子点能够有效地吸附到ZnO纳米棒上。通过研究发射衰减，证实了ZnO纳米棒对CdSe量子点的猝灭作用，并获得了1×10⁸ s⁻¹的电子转移（从量子点到ZnO）速率常数。所制备的QDSSC的效率为0.66%，在400 nm处实现了22%的入射功率转换效率。
