在光束诱导电流(Light Beam Induced Current,简称LBIC)成像技术的基础上,我们从理论和实验上分析了光束诱导电压(Light Beam Induced Voltage,简称LBIV)成像的机理。通过建立光束诱导电压成像的理论模型,认为光束诱导电压成像的测量值是一个平衡电压值,而不是光照区域的局域开路电压,我们在一块复合分布不均匀的单晶硅太阳能电池上验证了这个结论。这为改进光束诱导成像技术奠定了基础。
Based on the Light Beam Induced Current (LBIC) imaging technique, we theoretically and experimentally analyzed the mechanism of Light Beam Induced Voltage (LBIV) imaging. By establishing a theoretical model of beam-induced voltage imaging, we consider that the measurement of beam-induced voltage imaging is an equilibrium voltage rather than the local open-circuit voltage in the illuminated area. We validated a single-crystal silicon solar cell with a heterogeneous distribution of heterogeneity This conclusion. This laid the foundation for improved beam-induced imaging.
