Ultimate transistor electronic load for electrical performance : Measurement of photovoltaic devices using pulsed solar simulators
The manufacture of photovoltaic modules requires electrical performance measurement of the finished product under standard test conditions. Present electronic loads at ESTI are working unsatisfactorily during characterisation under simulated flash light (2 ms) due to oscillations caused by the active feedback, and a poor distribution of measuring points. A new electronic load (UTEL) has been developed, capable of measuring solar cells and panels up to 200 W, having active forward coupling rather than feedback, and an improved distribution of measuring points. This improves accuracy and reproducibility; the UTEL can also measure I-V curves at low irradiance and is adjustable for all pulsed solar simulators. This paper describes the entire measurement system and the results of several measurements.
