<p><P>PROBLEM TO BE SOLVED: To provide a method for measuring solar cell characteristics, in which characteristic of a large area solar cell can surely be measured easily with higher accuracy, using a small-sized solar simulator. <P>SOLUTION: In the method for measuring the characteristics of solar cell 20 formed of a plurality of unit cells, individual unit cell characteristics are measured and the cell characteristic of a thin-film solar cell group as a whole is calculated, on the basis of the serial circuit calculating formula or parallel circuit calculating formula which is determined according to serial or parallel circuit. In this case, as the irradiation pulse beam, the light beam from the lamp source of the solar simulator 1 is guided to an irradiation head 6 facing the unit cells with a flux of a plurality of optical fibers 5, in order to obtain the uniform irradiation light beam converted, in matching with the shape of plane of the unit cell. Thereafter, this irradiation light beam is sequentially irradiated to a plurality of unit cells for the purpose of voltage-current measurement with a measuring apparatus 8, sequentially measuring the unit cell characteristics. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
