Solar cell analysis system

Short circuit current

Instead of sweeping the entire IV-curve during the short illumination with a Xenon flash we maintain the solar cell in short circuit during the decay to measure the short ciruit current only.

If an EQE is available the spectral mismatch is calculated automatically and the result used as a setpoint to regulate the intensity of the LED-array. Subsequently, the IV-curve is recorded without compromises in accuracy because plenty of time is available. The spectrum of the Xe-flash is filtered to match class A according to IEC 60904‑9.
