| Abstract: | The structure, the linking method and the working process of the automatic photovoltage spectrum measuring system which are composed of computer,scanning controller,grating monochromator and lock-in amplifier have been reported. The system raises the measuring efficiency 20 times in comparison with manual system, which makes it easy to measure photovoltage spectrum accurately at large wavelength range. The experimental results of the application of the system to measuring photovoltage spectra of AlAs/GaAs superlattices are also reported. |
