Optical and Electrical Analysis of Core-Shell ZnO/ZnTe Micropillar Solar Cells
This paper presents an investigation on the effects of micropillar physical parameters (height, pitch and diameter) on the optical and electrical performance of ZnO/ZnTe core-shell micropillar solar cells. It also studies the effect of the doping level in the absorber layer on the device's perf...

This paper presents an investigation on the effects of micropillar physical parameters (height, pitch and diameter) on the optical and electrical performance of ZnO/ZnTe core-shell micropillar solar cells. It also studies the effect of the doping level in the absorber layer on the device's performance considering the impact of Auger's recombination. A Finite-Difference Time-Domain (FDTD) solver, Lumerical, is used for the numerical analysis. Based on the range of parameters analyzed it was concluded that for a core-shell ZnO/ZnTe micropillar solar cell a 4 μm height, a 0.5 μm pitch, a 70 nm ZnTe shell thickness and a 2.16 x 10<sup>19</sup> cm<sup>-3</sup> doping concentration for ZnTe achieves an efficiency of 17%. |
