Measurement Elements for the Extraction of Photovoltaic Cell Parameters
In order to evaluate performance and optimize systems using solar energy, the properties of the photovoltaic (PV) cell need to be properly extracted. This study gives the measurement elements and techniques of computing significant PV features, such as short circuit, fill factor, efficiency and open-circuit voltage. Any of the methods include temperature-dependent analysis, impedance spectroscopy, current-voltage (I-V) curve tracing. Precision in measurement is enhanced through accurate sensing element, controlled lighting and data recording in real time. The functions in PV systems during these measurement techniques include efficient modelling, performance predictions as well as fault detection. The paper highlights the importance of proper methods of measurement on the enhancement of the photovoltaic technology functionality as well as design.
