Produção de filme condutor de grafite e quitosana modificado com zinco

Abstract

In this work, a possible application of graphite, chitosan together with zinc in the renewable energy industry will be presented. For this, it was proposed to synthesize zinc-modified graphite and chitosan films and then use this film in an electric current generator system working together with a broken silicon photovoltaic cell. The justification for producing this work is the increasingly accelerated growth of the photovoltaic cell industry and the lack of alternatives when it comes to reuse of broken silicon photovoltaic cells. Measurements were made of the dimensions of the films produced and their respective electrical resistances. The choice of film components is due to the favorable interaction between the compounds and because they are commonly used in work involving electrical conduction. The efficiency of the final system was evaluated by making voltage and current measurements with the system being in contact with solar radiation. Considering that this is a relatively simple methodology, and based on the results obtained experimentally, it is reasonable to infer that the adopted procedures can be improved and, thus, readjusted in order to reach a larger scale.
