We applied a pump-probe laser terahertz emission microscope to investigate dynamic response of photoexited carriers in a solar cell. We could clearly observe the change of terahertz radiation at the grain boundary in the polycrystalline silicon solar cell using the pump-probe methods, which could not be obtained by simple terahertz emission imaging.
We have succeeded in detecting the terahertz waves generated from the solar cell under the irradiation of femtosecond laser pulses. This technique has enabled to visualize instantaneous power generation in the solar cell.
