Abstract :
We observed waveforms and images of THz radiations from a triple-junction-solar-cell (TJSC) with InGaP-GaAs-Ge layered structure excited by wavelength-tunable laser pulses, and wavelength-dependent THz signals and images could be observed. The results indicate that characteristics of an each layer in TJSC can be extracted with this system.
