CIMPS is an universal photo- and spectro-electrochemical workstation for a wide field of applications. You can easily extend the basic CIMPS system with various options for special fields of photo-electrochemical research.


Energy Storage & Conversion

Our power potentiostats, electronic loads and multi-channels acquisition systems provide a smart system for research and investigation on batteries, fuel cells and super caps.



Electrochemical noise has become popular as a new method of corrosion detection and prevention. ZAHNER has developed the CorrElNoise® technique, the first method to obtain both, potential noise and current noise from one electrochemical source.


Solar Cells and Photovoltaics

Investigation of silicon solar cells (SC), dye sensitized SC, perovskite SC, Grätzel SC, organic photovoltaics (OPV), and other photoactive devices such as photo sensors. Determining power conversion efficiency, incident-photon-to-current-conversion efficiency IPCE, fillfactor and charge extraction. 

Depleting fossil energy resources and the climate change are forcing to look for alternatives. Here, photovoltaics have been seen as the most promising environmental friendly energy supply for the past decades.

The direct conversion of sunlight into electricity is emission free, quiet and reliable. With time, dozens of different solar cells types were investigated, but only a few have been established. Nevertheless, the urge of changing our way of energy production makes research in the field of solar cells absolutely essential. New materials have to be found showing high solar energy conversion efficiencies at low cost productions.
