Intensity Modulated Photocurrent Spectrometer

Intensity-modulated photocurrent spectroscopy (IMPS) is one technique that links the electrical and optical responses of the device. In intensity-modulated photocurrent spectroscopy testing, the device is irradiated with a sinusoidally varying modulated light intensity while maintaining a constant voltage and measuring the photocurrent.

Sample Requirements

• Powder: 50 mg.
• Thin films on ITO / FTO glass.
