The PL-SPV/IPCE1000 Steady-State Surface Photovoltage Spectrometer provides both steady-state SPV and IPCE (incident-photon-to-current efficiency) measurements. The former reveals charge separation, while the latter gives wavelength-resolved conversion efficiency of a device under applied bias.
A typical configuration includes a light source and monochromator, a sample chamber, lock-in detection, and bias control. Steady-state SPV uses modulated light to measure surface potential, while IPCE scans monochromatic light to obtain external quantum efficiency.
After loading the sample, first measure the dark baseline, then scan wavelength under illumination to obtain the SPV spectrum; switch to IPCE mode and scan each wavelength for quantum efficiency—all without damaging the sample.
Characterization conclusions must return to activity: verify the material's real activity with the PCX-50C Discover Multi-Channel Photocatalytic Reaction System or the PLR-GSPR, confirming that the characterization trend matches the reaction.

It integrates steady-state SPV (charge separation) and IPCE (wavelength-resolved conversion efficiency under bias) in a single instrument.
A light source with monochromator, sample chamber, lock-in detection, and bias control handle both SPV and IPCE scanning.
Verify its characterization trends with a reactor such as the PCX-50C Discover or PLR-GSPR to confirm they match real activity.
