Dye Solar Cell Testing
IMPS / IMVS
Intensity Modulated Photocurrent Spectroscopy and Intensity Modulated Photovoltage Spectroscopy (IMPS/IMVS) are techniques that can be used to characterize Dye-Sensitized Solar Cells (DSSCs). Our system utilizes two Gamry potentiostats to fully characterize DSSCs, allowing you to extract recombination and charge-extraction parameters.
One potentiostat drives an LED while the second potentiostat is used to characterize the cell. Data acquisition between the two potentiostats is synced so that phase information between the driving potentiostat and the acquiring potentiostat is obtained.
The system includes a miniature optical bench with a dummy cell for background subtraction. Our 3D-printed cell holder can accommodate large and small cells and our flexible configuration allows you to use any color LED. We have red, white (several temperatures), blue, orange, and yellow available. You could even provide your own LED. The system is fully controlled in our standard data acquisition software, Gamry Framework.
