In this study, the performances of a-Si: H(n-i-p) /µc-Si: H(n-i-p) tandem solar cell based on hydrogenated amorphous silicon (a-Si: H) and hydrogenated microcrystalline silicon (µc-Si: H) with thinner active layers were investigated by using numerical simulation. For simulation, a one-dimensional computer code AMPS-1D was used to investigat the effect of the top single cell n⁺ layer nature, the effect of the top single cell n⁺ μc-Si: H layer doping concentration (ND) and, the effect of the two active layers thicknesses, i-a-Si: H layer and i-μc-Si: H layer on the performances of the tandem cell. However, the merit figures, like J(V) characteristics at dark and under illumination, the electric fields, the energy band diagrams and, the cell output parameters are calculated and investigated.

According to our calculations it is found that, by using a n⁺µc-Si: H layer with a doping concentration value ND = 10¹⁹ cm^-3 instead of a n⁺ a-Si: H layer in the n-i-p top single cell the tandem solar cell performances were performed. It is also obtained, a values of 50 nm and 600 nm for the active layers i-a-Si: H and i-µc-Si: H thicknesses, respectively, are recommended for a-Si: H/µc-Si: H tandem solar cell good performances. Lastly, the tandem solar cell with top single cell n⁺µc-Si :H layer and with a thinner actives layers thicknesses has the higher output parameters (J_SC=10.52 mA/cm², V_OC=1414 mV, FF = 80.2% and, the efficiency = 12.14%).

在这项研究中，基于氢化非晶硅（a-Si：H）和氢化微晶硅（µc-Si：H）的a-Si：H（nip）/ µc-Si：H（nip）串联太阳能电池的性能通过数值模拟研究了具有更薄有源层的薄膜。对于仿真，一个一维的计算机代码AMPS-1D是用来investigat顶端单电池n的效果⁺层性质，顶单电池n的效果⁺μc-Si：H层掺杂浓度（ND）以及两个有源层厚度ia-Si：H层和i-μc-Si：H层对串联电池性能的影响。但是，需要计算和研究诸如黑暗和光照下的J（V）特性之类的优点图，电场，能带图以及电池输出参数。

根据我们的计算发现，通过在钳口顶部单电池中使用掺杂浓度值为ND = 10 ¹⁹  cm ^-3的⁺ µc-Si：H层代替了⁺ a-Si：H层，可实现串联太阳能进行电池性能测试。还可以得出，对于a-Si：H / µc-Si：H串联太阳能，建议有源层ia-Si：H和i-µc-Si：H的厚度分别为50 nm和600 nm。细胞性能良好。最后，具有顶部单电池n ⁺ µc-Si：H层和较薄的有源层厚度的串联太阳能电池具有较高的输出参数（J _SC = 10.52 mA / cm ²，V _OC= 1414 mV，FF = 80.2％，效率= 12.14％。
