Abstract (in Japanese) (See Japanese page) 
(in English) arious proposals using THz Time-Domain Spectroscopy (THz-TDS) have been performed in the semiconductor research field. Laser Terahertz Emission Microscopy (LTEM) acquires an image of the THz emission on a sample by scanning it with femtosecond laser pulses. The distribution of local photoexcited current can be visualized. We report on the results of the detection of THz waves generated from the multicrystalline silicon solar cell excited by femtosecond laser pulses and imaging the amplitude of THz waves, which reflect the instantaneous and local electric power generation. Moreover, we observed the decrease of intensity of THz radiation by CW laser illumination.
