Featuring flexible configuration, IMPS/IMVS Intensity Modulated Photocurrent Spectroscopy and Intensity Modulated Photovoltage Spectroscopy instruments allow use of any color LED. Setup includes dummy cell allowing background subtraction. Instruments are fully controlled in standard data acquisition software, Gamry Framework. By adding 2 potentiostats – one to drive LED and another to measure cell response - IMPS/IMVS can be used to learn recombination and charge-extraction characteristics.
