摘要

在有机薄膜太阳能电池中插入周期性圆柱形银纳米天线可以提高光吸收效率。在本研究中，我们使用遗传算法对纳米天线进行几何优化。数值计算以有限元法为基础。考虑了四种不同几何参数的新型纳米天线，即锥形天线、锥形干状天线、指数1型锥形干状天线和指数2型锥形干状天线。我们发现，与其他天线相比，主干圆锥指数2天线能更好地解决不同入射角的光。

Geometry optimization of plasmonic nanoantennas for organic solar cells

It is known that insertion of periodic cylindrical silver nanoantennas in organic thin-film solar cells increases efficiency of light absorption. In this study, we perform a geometric optimization of the nanoantennas by using genetic algorithm. Numerical calculations are based on the method of finite elements. Four types of new nanoantennas with different geometrical parameters were considered, namely, conical antenna, trunk of conical, trunk of conical exponential 1 and 2 ones. We have found that the trunk conical exponential 2 antenna provide a better solution for different angle of light incidence as compared with the others.
