EVALUATION METHOD AND EVALUATION DEVICE FOR SOLAR CELL

摘要

PROBLEM TO BE SOLVED: To provide an evaluation method and evaluation device for a solar cell capable of quantitatively and efficiently evaluating a solar cell with high accuracy without depending on the types of a measuring apparatus and the solar cell.SOLUTION: The evaluation method for a solar cell includes a process for measuring the external quantum efficiency of a solar cell to be evaluated, a process for acquiring a light emission image of the solar cell to be evaluated in a light-emitting state by using a camera capable of displaying a characteristic corresponding to light emitting intensity in each pixel, and an open circuit voltage map acquisition process for acquiring an open circuit voltage map obtained by visualizing the solar cell to be evaluated in each unit of a unit to be evaluated that is either a pixel of the camera or a cell of the solar cell to be evaluated on the basis of information obtained from the external quantum efficiency and information of the light emission image about which the sensitivity information of the camera is calibrated by a light emission standard in which the absolute light emission intensity and a current characteristic during light emission are quantized.SELECTED DRAWING: Figure 2(e)
