CIMPS Add-On for QE/IPCE/PCS Measurements

Photo-Electrochemical photo current spectra system for quantum efficiency / incident photon conversion efficiency measurements. Extend the scope of your CIMPS system to the examination of solar cells, DSSC, etc.

Equipped with the tuneable light source TLS03, one of the core applications of PCS is measuring the Quantum Efficiency QE or Incident Photon Conversion Efficiency IPCE of organic and dye sensitized solar cells in the wavelength range from typical 365 nm up to 1020 nm (TLS03) with optional UV range extension, representing for the most effective range of solar light. Like the standard light sources for CIMPS, the TLS03 are based on the state-of-the-art LED technology. Switchable white background illumination helps to speed up measurements at DSSC and enables investigations on tandem solar cells. PCS profits from the modulation capabilities of LEDs just as CIMPS does. No mechanical choppers are necessary and instead of the more noise-sensitive Lock-In-technique the advantages of coherent frequency analysis technique can be used. PCS comes up as a plug & play application fully calibrated and equipped with the outstanding comfort of Thales: spectral data can be analyzed with the on-board package “light spectra analysis”, spectral data files are covered by the preview-support of the Windows® file explorer and can be exported in manifold ways as high-quality vector graphics, bitmaps and ASCII data lists. You may view and export data, while measurements are running.

Apart from recording photocurrent spectra the TLS03 can be used like standard light sources of the CIMPS core system.

TLS03 tunable light-source:
Wavelength range: 295–1020 nm
typ. res.: 1 nm@430-720 nm,15 nm@295-420 nm, 40 nm@735–1020 nm
typ. line width: 10 nm@295-720 nm, 50 nm@735–1020 nm

Photo-Electrochemical Light Emission Measurement System

Extend the scope of your CIMPS system to the examination of OPV, LED, OLED, etc.

Similar to the light absorbance measurement package, this option complements CIMPS by a UV-VIS-IR spectrometer to enable spectral resolved light emission measurements. For integral emission, an additional NIST traceable calibrated photo-detector can be added. Like with CIMPS-abs, automatic spectra series measurement vs. cellvoltage, current, time can be performed and additional series parameters like temperature, voltage and pH can be used optionally. Of course, emission spectra recording can be triggered also manually while controlling the electrochemical parameters. Like for CIMPS-abs, the light spectra analysis package within Thales supports single / multi-spectra 2-D, multi-spectra 3-D and contour plot visualization for instance as emission, emit-Schematransmittance, absorbance, extinction in linear or logarithmic scale vs. wavelength or wave-number. Data export can be done in form of ASCII-data, as bitmap or as Windows®-EMF graphics via clipboard copy & paste or as file.

Photo-Electrochemical Workstation

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 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 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 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/Zennium system, controls amplitude and modulation of the light source over a wide range of frequencies.

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.
