Quantum efficiency measurement

CIMPS-PCS

Tuneable light source
CIMPS-IPCE
CIMPS pcs allows "quantum efficiency" (QE) or "incident photon to current efficiency (IPCE)" measurements for the characterization of photoelectrodes or solar cells. The CIMPS pcs does not include a mechanical chopper and the IPCE measurements are not carried out via noise-prone Lock-In techniques but are carried out via intensity-modulated photocurrent spectroscopy. The LEDs based tuneable light source (TLS) used in CIMPS pcs is available for a wide wavelength range (with and without UV extension). A feedback sensor is incorporated in the TLS which ensures illumination with the correct light intensity.

An additional constant white background light is also incorporated in the TLS which allows IPCE measurements for the solar cells with high light intensity threshold for photocurrent. The effect of the constant white light is removed from the IPCE measurements.

The CIMPS-IPCE can be used for all standard electrochemical or photoelectrochemical measurements which are possible with the CIMPS.
