Abstract
An inspecting device serves to inspect a solar cell. The inspecting device includes an irradiation part for irradiating with pulsed light and a detection part having a detector for detecting an electromagnetic wave pulse radiated from the solar cell depending on the irradiation with the pulsed light. The detector detects an electric field intensity of the electromagnetic wave pulse depending on irradiation with probe light emitted from a light source (a femtosecond laser) of the pulsed light. Moreover, the inspecting device includes a delay part for delaying a timing for detecting the electromagnetic wave pulse in the detector. Furthermore, the inspecting device includes an electromagnetic wave pulse analysis part for detecting a negative peak of the electric field intensity in a temporal waveform of the electromagnetic wave pulse.
