Abstract
Photovoltaic scavenging circuits have been presentedto reduce installation and maintenance costs of wirelesssensor networks. When small-size photovoltaic modules areadopted, optimizing the efficiency of the harvesting process andtracking theMaximum Power Point (MPP) becomes very difficult,and the development of a photovoltaic harvester has to bepreceded by extensive simulations. The paper focuses on thedefinition of the model for a small PV cell allowing the simulationof harvester systems. The model is validated on a case study ofMPPT circuit for sensor networks.
