二、System outward:
三、Functional explanation of application:
This set of solar spectral response / QE / photocurrent conversion efficiency measurement system can provide
spectral response measurement of photovoltaic material, which is generally called QE measurements. A light
source system used, after spectroscopic spectrometer can provide specific single wavelength is irradiated onto the
sample, the sample generated photocurrent signals are converted via a system digital signal processor for signal
voltage and then sent into a computer to do analysis processing unit, the computer can control the various parts of
the system components, automatic data collection, analysis, and file access; and to make the system calibration
and produce output reports.
