This paper introduces a novel lateral quantum well solar cell, and investigates the effects of structural parameters of these nanostructures on the device’s performance. For modeling the device, first, the absorption coefficients and the reflectance parameters of the device at different regions were calculated. Those parameters were then used to find the system’s optical generation rate. Finally, while considering all the radiative and non-radiative recombinations, the continuity and drift-diffusion equations were solved to find the dark- and photo-currents. The results indicated that applying quantum wells to the traditional classical solar cells could noticeably increase the system’s efficiency. Additionally, it was found that efficiency was heavily dependent on the values of different geometrical parameters, including the active layer’s thickness and the width of the wells and barriers. Moreover, it was shown that modifying some structural parameters such as the barrier mole fraction could noticeably influence the solar cell’s characteristics. Therefore, to obtain good efficiency it is necessary to optimize these parameters.

本文介绍了一种新型的横向量子阱太阳能电池，并研究了这些纳米结构的结构参数对器件性能的影响。为了对设备建模，首先，计算设备在不同区域的吸收系数和反射率参数。然后使用这些参数来找到系统的光学发生率。最后，在考虑所有辐射和非辐射复合的同时，求解了连续性和漂移扩散方程，以找到暗电流和光电流。结果表明，将量子阱应用于传统的经典太阳能电池可以显着提高系统的效率。此外，还发现效率在很大程度上取决于不同几何参数的值，包括有源层的厚度以及阱和势垒的宽度。而且，已经表明，改变一些结构参数例如势垒摩尔分数可以显着影响太阳能电池的特性。因此，为了获得良好的效率，必须优化这些参数。
