摘要
本研究利用 Quokka3 这一先进的太阳能电池仿真程序，专门为互嵌背接触（IBC）晶体硅（c-Si）太阳能电池量身定制。通过细致的 Quokka3 仿真，科学地探讨了太阳能电池背面的若干几何和晶片特性对 IBC 晶体硅太阳能电池电流-电压（I-V）性能的影响。研究涉及的参数包括晶片厚度、体寿命、电阻率、发射极和背面场面积分数以及前后表面钝化。为提高 IBC 太阳能电池的效率，提出了这些参数的最佳值。这些建议包括 70% 的发射极比例、200 μm 以上的晶片厚度、1 Ω cm 的晶片电阻率以及至少 10 ms 的晶片整体寿命。此外，在电池不短路的条件下，还显示出实现更高的电池效率（高达 26.64%）的潜力。
Systematic Modeling and Optimization for High-Efficiency Interdigitated Back-Contact Crystalline Silicon Solar Cells
This study utilizes Quokka3, an advanced solar cell simulation program, specifically tailored for interdigitated back-contact (IBC) crystalline silicon (c-Si) solar cells. Through meticulous Quokka3 simulations, the influence of several geometric and wafer characteristics of the solar cell backside on current–voltage (I–V) performance has been scientifically explored for IBC c-Si solar cells. The investigation encompasses parameters such as wafer thickness, bulk lifetime, resistivity, emitter and back surface field area fraction, and front- and rear-surface passivation. Optimal values for these parameters have been proposed to enhance the efficiency of IBC solar cells. These recommendations contain an emitter percentage of 70%, a wafer thickness ranging from 200 μm, a wafer resistivity of 1 Ω cm, and a wafer bulk lifetime of at least 10 ms. Moreover, under conditions where the cell is not short-circuited, the potential for achieving higher cell efficiency, up to 26.64%, has been shown.
