| 摘 要： | 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。

| Abstract: | We analyze the mechanism of Laser Beam Induced Voltage （LBIV） method from theory and experiment referring to Laser Beam Induced Current （LBIC） method.By analyzing the established model of LBIV measurement,a conclusion is raised that the LBIV value is the balance voltage of dark area and the laser beam illumination area instead of local open circuit voltage of the laser beam illumination area.This conclusion is verified on a monocrystalline silicon solar cell with uneven recombination distribution.The research lays the foundation for the improvement of laser beam induced technical. |
