STUDY ON THE PERFORMANCE OPTIMIZATION OF THIN FILM SILICON AND BIFACIAL PHOTOVOLTAIC MODULES THROUGH OUTDOOR VARIABLES
type: CreativeWork
description: Main object of this Ph.D. work has been the performance optimization of thin film Silicon and bifacial photovoltaic (PV) devices, by means of an in-depth study of their behavior by varying the outdoor variables affecting their electrical performance. The first part of such work has been focused on the study of performance instability phenomena affecting tandem amorphous/microcrystalline Si mini - modules under variable working conditions in terms of illumination, voltage stresses (both in DC reverse bias and in direct bias in Maximum Power Point) and temperature. An accurate analysis of the causes of such phenomena has been carried out, by thoroughly studying the effects on the performance of such PV devices in actual outdoor operation, due to variations of solar spectrum and of solar cell operating temperature. The relevant role played by the latter outdoor variable on the power conversion efficiency of such devices has been highlighted and demonstrated. Considering the crucial importance which the study of electrical behavior of high efficiency bifacial PV devices is currently assuming, essentially due to the fast development and diffusion of such promising devices, the second part of this work has concerned the performance optimization of bifacial PV systems. For such purpose, a novel analytical model to accurately predict the electrical performance of bifacial PV modules, usable for any geographical location, has been developed and its accuracy validated through experimental tests outdoor. This has allowed, on one hand, to analyze in-depth the behavior of bifacial devices and their performance optimization, by varying the main outdoor variables which determines such performance in real operating conditions. On the other hand, it has been possible to predict the electricity generation of bifacial PV systems with and without solar trackers for different geographical locations, by highlighting whether and where the solar tracker adoption is convenient for optimizin…
