This paper mainly focuses on model of photovoltaic cell for energy harvesting application (EHV). This model is developed using the standard simulation software LTspice to explore the effect of electrical and physical parameters on Current-Voltage (I-V) and Power-Voltage (P-V) characteristics of photovoltaic cell (PV). The proposed model is based on mathematical equations and is described through an equivalent circuit. The developed model serves to specify the optimal conditions for operating
more &raquo; ... PV cell and define the maximum power point (MPP). It also allows the prediction of PV cell behavior as a function of temperature and ambient radiation. To demonstrate the validity of the generated model, an experimental test was performed for a PV cell (of type"ASI" from SCHOTT Company). Experimental and technical data display a good agreement with the simulated findings. Key words_ Photovoltaic cell (PV), energy harvesting (EHV), LTspice, generated model, I-V and P-V characteristics, maximum power point (MPP).
