This workshop is a research meeting opened to all academic, researchers, professional and students, to discuss innovative ideas and diverse topics on Photovoltaic cell and System. Because the photovoltaic revolution is advanced as an outcome to all our problems of electrical energy production, the workshop concentrates its activities to the proposal and discussion to minimize the cost of the realization and electrical energy provided by photovoltaic cell and panels PV, optimize the photovoltaic system structures allowing to transfer the product energy to the load (Battery…), good control of charge/discharge lead acid batteries and solar tracking PV panels. Papers accepted and presented in this Workshop will be published, with a preferential price, in the special issue: Optimization of Photovoltaic Cell and System for a Better Exploitation of the Solar Energy
