“…11b shows a light-induced current map along with schematics of the device and an optical photograph of the device. Nakatani and co-workers have recently demonstrated an elegant modification of the LBIC technique, 193,207 where the photocurrent of the solar cell is detected using a SQUID magnetometer (Fig. 11c).…”

“…1, because the detected magnetic field is sensitive to the vertical component of the magnetic field. In our previous work 3) , we reported that the magnetic images of a solar cell taken by the laser-SQUID microscope were similar to the current images taken by laser beam induced current imaging (LBIC) technique, which is widely used for solar cell evaluations [4][5][6] . Those images showed the fine contrast changes corresponding to the defects.…”

“…We have developed a laser-superconducting quantum interference device microscope (a laser-SQUID microscope), in which a scanning SQUID probe microscope is combined with a laser excitation system [1][2][3] . The magnetic field can be induced by the photocurrent from the laser spot on a semiconducting sample excited by the laser.…”
