SOLAR CELL EVALUATION METHOD, EVALUATION DEVICE, MAINTENANCE METHOD, MAINTENANCE SYSTEM, AND METHOD OF MANUFACTURING SOLAR CELL MODULE |
摘要 |
A method and device for evaluating a solar cell each of which makes it possible to easily evaluate a defect of a solar cell especially in such a manner that an internal cause defect and an external cause defect are distinguished from each other. The device includes: electric current passing means for passing, in a forward direction, an electric current through a solar cell element constituting the solar cell; light emission detecting means for detecting, out of light emitted from the solar cell element due to the electric current passed by the electric current passing means, light in a first range of wavelengths from 800 nm to 1300 nm and light in a second range of wavelengths from 1400 nm to 1800 nm; and judging means for distinguishing between an internal cause defect and an external cause defect. |
