近年来,量子点敏化太阳能电池的光电转换效率大幅提升,得到了研究者的广泛关注.量子点敏化太阳能电池的工作机制和染料敏化太阳能电池类似,利用量子点替换传统染料具有以下优点:(1)量子点的消光系数高达105 L/(mol cm);(2)量子点的光谱响应可以通过改变其尺寸而方便地调节;(3)相较染料而言,量子点具有较好的抗水氧性;(4)量子点具有多激子效应,有望发展为高效率的光伏器件.尽管量子点敏化太阳能电池有诸多的优点,但就目前的研究而言,其光电转换效率(~6%)仍然远远落后于 In recent years, the photoelectric conversion efficiency of quantum dot-sensitized solar cells has been greatly increased, attracting a great deal of attention from researchers. The working mechanism of quantum dot-sensitized solar cells is similar to dye-sensitized solar cells. The use of quantum dots to replace traditional dyes has the following advantages : (1) the extinction coefficient of the quantum dots is as high as 105 L / (mol cm); (2) the spectral response of the quantum dots can be easily adjusted by changing its size; (3) the quantum dots have a better color than the dyes (4) Quantum dots have multi-exciton effect and are expected to develop into high-efficiency photovoltaic devices.Although quantum dot sensitized solar cells have many advantages, the photoelectric conversion efficiency (~ 6%) is still far behind
