Physical parameters of a photovoltaic cell can be determined from its experimental current-voltage characteristic. The accurate determination of these parameters is particularly dependent on experimental measurements conditions. The reliability of measurements of temperature variations and intensity of solar radiation are dependent on the sampling time of the measurements. Controlling the radiation...
In this paper we present the study of a hybrid photovoltaic/thermal panel (PV/T). It consists of a sheet form with several inputs-outputs opening (I/O) of coolant fluid, confined between the rear face of the panel and a Plexiglas support plate. The system is designed to maintain the temperature of the PV panel near ambient temperature. Heat transfer through the components of PV/T collector, taking...
In this work, we study the influence of various technological factors on silicon solar cells efficiency. We use simulation by personal computer one dimension software package (PC1D) solving equations describing the transport of electrons and holes in devices based on semiconductor materials. We highlight the most critical steps and the technological factors to be improved to increase solar cells efficiency...
