摘要
综述了量子点敏化太阳能电池的结构、工作原理和量子点敏化剂的特性,并根据量子点敏化剂的组成进行分类,分别介绍了近期研究进展。量子点敏化剂的结构以及宽带隙材料的纳米结构对太阳能电池的性能都有影响,若制备的敏化剂粒径呈梯度分布,则可充分发挥量子点敏化剂的宽吸收特性;量子点和垂直生长在导电衬底上的一维纳米线或纳米管阵列相结合,光生电子直接传输到电极,能有效提高量子点敏化太阳能电池的效率。最后,结合现存问题提出了今后的研究方向。
The structure and operation principle of quantum dot sensitized solar cells, and the feature of quantum dot sensitizer are reviewed. Quantum dot sensitizer are classified according to their composition, the corresponding research progress are introduced. The structure of quantum dot sensitizer and large band gap materials affect the performance of solar cells markedly. If the size of quantum dot sensitizer are gradient increase, a wide scope of sunlight can be absorbed. Besides, quantum dot sensitizer attaches on one-dimensional nanowires or nanotubes array which stand on conducting substrate, then the photo generated electron will be transferred to electrode directly, the efficiency of solar cells can be improved obviously. At last, the present problems and research direction in the future are also described.
