Preparação de fotoeletrodo utilizando óxido de grafeno aplicado em célula solar sensibilizada por corante.

Abstract

Dye-sensitized solar cells is a very promising emerging technology because it presents greater theoretical efficiencies than solar cells already on the market, in addition, it promises to significantly reduce polluting gases, that is, environmentally friendly. In this work, the preparation of a dye-sensitized solar cell will be presented with a very promising material due to its excellent properties, such as: optoelectronic, mechanical, thermal and chemical resistance, graphene oxide used as a counter electrode and which has a wide potential to replace or modify the traditional materials that are commonly used in the manufacture of solar cells. These cells are characterized by the I-V current-potential curve, highlighting the values obtained from the parameters with emphasis on the efficiencies found using two sensitizers, dye N3 and dye N-719, which were used to sensitize the TiO2 films that make up the photoelectrode of the cell. This experiment proved effective for the development of dye-sensitized solar cells (DSSC).
