Photovoltaic Spectrometer is a complete experimental setup for solar cells spectral response investigation. The sample is illuminated with a monochromatic beam produced by the Monochromator with two types of light sources at the entrance: Xenon Lamp and Halogen Lamp. Both lamps provides wavelengths range that covers UV, VIS and IR light. Furthermore, the sample may be excited with a normalized white AM1.5G light from an additional Xenon Lamp combined with the Air Mass Filter. The examined cell is placed on a motorized vacuum XY Table, with a manual Z shift. Measurements are performed in a chamber that screens the setup from ambient light and external EM fields. The incident light intensity, is monitored with a Dual Band Si/InGaAs Photodiode. All the system components are fully automated, controlled via software.
The system consists of:
Photocurrent measurement/ Reflected flux measurement/ Built-in photodiode for Transmitted flux measurement
Instrument performance may be tailored to the certain requirements..
Dual Band Si/InGaAs Photodiodes are used to monitor the incident light intensity, the flux transmitted through the sample and the flux reflected by the sample.
Photocurrent measured for the standard crystalline silicon solar cell as a function of the incident wavelength.
