Photovoltaic spectrometer is a complete setup for solar cells’ spectral response investigation.
A sample is illuminated by a monochromatic beam, up to a few millimeters in diameter, in the ultraviolet, visible and infrared range. Additionally, the sample may be excited by a normalized white AM1.5G light. The cell is placed on a motorized vacuum XY table, with a manual Z shift. The measurement is performed in a chamber that provides screening from external light.
Reflected flux measurement
The Kelvin probe system allows precise measurement of work function of different semiconducting and conducting materials with high precision and accuracy
Photoelectric spectrometer serves as a scientific tool to automatically characterize photoelectrical properties (photocurrent, photovoltage) of wide band gap semiconductors
