Abstract

The modelling and determination of the geometric parameters of a solar cell are important data, which influence the evaluation of its performance under specific operating conditions, as well as its industrial development for a low cost. In this work, an n+/p/p+ crystalline silicon solar cell is studied under monochromatic illumination in modulation and placed in a constant magnetic field. The minority carriers’ diffusion coefficient (D(ω, B), in the (p) base leads to maximum values (Dmax) at resonance frequencies (ωr). These values are used in expressions of AC minority carriers recombination velocity (Sb(Dmax, H)) in the rear of the base, to extract the optimum thickness while solar cell is subjected to these specific conditions. Optimum thickness modelling relationships, depending respectively on Dmax, ωr and B, are then established, and will be data for industrial development of low-cost solar cells for specific use.
共振频率下的扩散系数在n+/p/p+硅太阳能电池最佳基底厚度测定中的应用
太阳能电池几何参数的建模和确定是影响其在特定工况下性能评价和低成本产业化发展的重要数据。本文研究了在单色照明调制和恒定磁场下的n+/p/p+晶体硅太阳能电池。少数载流子在(p)基中的扩散系数D(ω, B)在谐振频率(ωr)处达到最大值(Dmax)。将这些值用于基底后部交流少数载流子复合速度(Sb(Dmax, H))的表达式中,以提取太阳能电池在这些特定条件下的最佳厚度。然后建立最佳厚度建模关系,分别取决于Dmax, ωr和B,并将为特定用途的低成本太阳能电池的工业开发提供数据。
