摘要

The paper refers about a possibility to check recombination rate distribution over the area of power (large-area) solar cells from measured values of open circuit voltage V_(OC) using local irradiation by monochromatic light of different wavelengths (LBIV - Light Beam Initiated Voltage). The method can give information both about recombination centres distribution in large-area solar cells and surface recombination rate at the antireflection coating. From V_(OC) distribution, also position and extent of local defects can also be determined. The method can be used to investigate the influence of technology on characteristics of solar cells as an in-process checking with the aim of increasing efficiency and reliability of solar cells.
