Solar cell calibrator
for accurate characterization of photovoltaics

Helios solar cell calibrator is a tailored solution for accurate characterization of photovoltaics. It combines high current nulling amplifier and current-to-voltage converter with low noise bandpass filtered voltage amplifier. The four-point measurement circuitry enables the compensation of wire and junction resistances which would otherwise generate significant voltage over the measured photovoltaic. Helios provides a direct solution to meet the requirements for photocurrent measurements in spectral responsivity characterization, as specified in IEC 60904-8.

The bandpass filter has selectable gain ranging from 1 to 107, and selectable bandwidth up to 10 kHz. Standard model is suitable for photocurrents up to 10 A and can compensate wire and junction resistances up to 300 mΩ. Higher currents and frequencies are available upon request.
