Investigation of Spectral Response Measurement Technology for Silicon Solar Cells

The principle of Spectral response and the measurement technology for solar cells were investigated.Base on quantum efficiency dependence on absolute spectral response,external quantum efficiency was deduced by the measuring data of the absolute spectral response.A highly automatic spectral response measurement system was developed for silicon solar cells using virtual instrument technology base on LabVIEW which integrated software of computer with monochrometer,lock-in amplifier and other instrument hardware systematically.The range of the scanning wavelength was 400 nm to 1 200 nm and the minimum step wavelength was 1 nm which could meet the requirement of spectral response measurement for silicon solar cells.Several measurement results showed that the measurement system has highly repeatability and accuracy through measuring the spectral response and quantum efficiency under the bias light of silicon solar cells with this measurement system.
