Photovoltaic Testing System

This system includes either a 150W Xenon or 250W OTH lamp and a monochromator to tune the light source. A source meter used as an active load permits operating the test cell at various load conditions, includ- ing short-circuit, compensating for a series resistor re- quired to sense the current produced by the modulated monochromatic light. This sensed current plus a refer- ence signal at the frequency of the light modulation are both fed into the precision lock-in amplifier to allow measurement of the photocurrent generated by the modulated monochromatic light.
The PTS-1 features all the software required for l- V Curves and Spectral Response measurements. Main parameters of these measurements are displayed by the software, including the most important graphs typi- PTS Cell Testing System cally required by researchers and the industry. Option- ally, our software development group offers to develop whatever is required to meet your demands.
