This work mainly focuses on modeling the impact of bulk resistivity $ \rho_b $ on the bifacial n-type passivated emitter rear and totally diffused rear-junction (n-PERT-RJ) solar cells using Quokka3. Through simulation, under the front illumination, the light-generated excess carrier flow behavior in the bulk is studied. The regulatory function of the rear-junction solar cells’ bulk on the electron flows distributary is discussed. Finally, how the different $ \rho_b $ values affect the hole-current flow behavior and the FSF performance is revealed. This explains very well the reasons for decreasing short-circuit current J_SC because of the low $ \rho_b $ wafers in n-PERT-RJ solar cells. The studies also provide insights on the lowest value of $ \rho_b $ that can be applied to n-PERT-RJ solar cells without the efficiency deterioration. We also simulated the n-PERT-RJ solar cell performance and bifaciality when applying different $ \rho_b $ values under rear illumination. Last but not the least, investigation on how $ \rho_b $ affects the output performance will be extended to when n-PERT-RJ solar cells are served as the bottom subcell in a four-terminal tandem configuration.

模拟体电阻率对双面 n-PERT 后结太阳能电池的影响

这项工作主要侧重于模拟体电阻率的影响 $ \rho_b $ 在双面 n- 型钝化发射极后和全扩散后结（n-PERT-RJ) 太阳能电池使用 Quokka3。通过仿真，研究了在前照度下光生过剩载流子在体中的流动行为。讨论了后结太阳能电池体积对电子流分布的调节作用。最后，如何不同$ \rho_b $值影响空穴电流流动行为，并揭示 FSF 性能。这很好地解释了短路电流降低的原因J_SC因为低$ \rho_b $ 晶圆 n-PERT-RJ 太阳能电池。这些研究还提供了关于最低值的见解$ \rho_b $ 可以应用于 n-PERT-RJ 太阳能电池的效率不会下降。我们还模拟了n-PERT-RJ太阳能电池在应用不同时的性能和双面性 $ \rho_b $后照度下的值。最后但并非最不重要的，调查如何$ \rho_b $ 影响输出性能将扩展到当 n-PERT-RJ 太阳能电池用作四端串联配置中的底部子电池。
