Single Photon Emission Computed Tomography
The principle and image properties of single photon emission computed tomography are introduced.
In this paper, we present a study on the behavior of a polycrystalline silicon cell, specifically the NPP+ structure. The simulation of this structure is done using the PC1D software; this latter allows simulating different structures of photovoltaic cells. The general purpose of the present work is focused on the study of the manner that the cell physical parameters evolve in order to extract the optimal values and then increase the conversion efficiency. The simulation of several parameters such as doping, texturing, textured surface depth, series resistance, shunt resistance, carrier life time and others parameters, make it possible to choose the right parameters values to be used. In this work the efficiency of this studied structure reaches a value of 23%, which represents a good value for this type of cell.
