摘要

在有效质量近似下，通过变分理论计算了应变纤锌矿ZnSnN

/In

N柱形量子点的带隙，进而利用细致平衡理论，研究了柱形量子点太阳能电池的转换效率在多重激子效应以及内建电场的影响下随量子点半径、高度和In组分的变化关系。结果表明，量子点太阳能电池的转换效率随着量子点半径、高度以及In组分的增加单调增加。多重激子效应能够明显提高太阳能电池的转换效率，但是内建电场会使得太阳能电池的转换效率明显降低。

Abstract

Within the effective mass approximation

the band gap of strained wurtzite ZnSnN

/In

N cylindrical quantum dot is calculated theoretically by a variational method. Furthermore

based on the detailed balance theory

the relationship between the conversion efficiency of cylindrical quantum dot solar cell and the radius

height and In component of quantum dot under the influence of built-in electric field and multiple exciton generation are studied. The results show that the conversion efficiency of quantum dot solar cell increases monotonously with the increase of quantum dot radius

height and In component. The multiple exciton generation can obviously improve the conversion efficiency of solar cells

but the built-in electric field can reduce the conversion efficiency of solar cells significantly.
