CIMPS

Controlled Intensity Modulated Photo Spectroscopy

CIMPS System with XPOT The Zahner CIMPS system based on LED arrays brings an additional advantage compared to the IMPS described in the literature: a control loop regulates light intensity and modulation and keeps it absolutely stable. The automatic comparison between set value and sensed intensity eliminates the influence of non-linearity, ageing and temperature drift. Furthermore, it allows the direct calibration of the light source in units of intensity (W/m2).

The CIMPS package consists of several components, working together in a plug & play application, including software and an overall calibration of the system. An ElectroChemical Workstation ECW IM6 or ZENNIUM acts as a Frequency Response Analyser and as a support unit (Potentiostat / Galvanostat) for the cell under test. The IM-series workstations are renowned for their high precision, ease of use and comprehensive software. A slave potentiostat, driven by the IM6/IM6e system, controls amplitude and modulation of the light source over a wide range of frequencies.

PECC An optical bench carries the housing of the light source with the integrated photo-amplifier and the slide with the photo-electrochemical cell (PECC-1 and PECC-2). A photodiode sensor is mounted near the site of the cell’s light inlet, adjustable in height and angle. Depending on the application, you can chose from different types of light sources (see table).

CIMPS Software Option CIMPS Software Option

The ZAHNER CIMPS measurement system has been designed to match the special demands of dynamic photo-electric investigations. Besides traditional electrochemical investigations supported by the Thales software package a variety of special photo electric measurements can be done easily with the CIMPS option:
  • SC fill-factor efficency
  • Maximum power
  • Intensity modulated photocurrent spectroscopy (IMPS)
  • Controlled IMPS (CIMPS)
  • Intensity modulated photovoltage spectroscopy (IMVS)
  • Controlled IMVS (CIMVS)
  • Charge extraction after N. W. Duffy, L. M. Peter et. al.
  • Light transient measurements
  • Time domain measurements
  • DC vs. intensity transfer functions
  • Chopped light voltammetry (CLV manual)
