Estudo do comportamento de vidros em função da temperatura para uso como substrato em aplicações fotovoltaicas e estudo teórico de um pirolisador

Abstract

The use of a glass substrate for use in photovoltaic system is very common, however, the substrates are subjected to high temperatures as in the case of obtaining glass covered with SnO2 (tin dioxide), where the operating temperature reaches values close to 600 ° C. Thus, a study of the glass expansion behavior with different thicknesses under temperature of 600 ° C was conducted in order to observe the influence of the same glass used as substrates, and thus, prevent possible defects cracks and broken glass inside the oven. Besides the study associated with the glass, a theoretical design of a pyrolyzer with these characteristics has been designed for obtaining layers of SnO2 on the glass, adding innovations such as the use of natural gas burning in porous media as heat source and the use of a pyrolyzer to replace the resistive furnaces.
