O emprego de um sistema individual automático de geração/conversão de energia solar em elétrica, com seguimento automático de intensidade luminosa, como instrumento didático de incentivo, motivação e suporte ao ensino de tópicos interdisciplinares de Física Moderna

Abstract

This dissertation details the design, construction and testing of an integrated educational product consisting of an isolated experimental system for generating and converting solar energy into electrical energy with automation of the capture of teh electromagnetic radiation intensity together with a booklet that presents the basic foundations of the physics phenomena, relating to topics of modern physics and physics of materials, involved with the construction, functioning and application of manufactured equipment. The experimental system consists of two parts: the first is composed of a medium-sized photovoltaic panel, affixed to a support system that has the ability to rotate the base of the panel in three spatial degrees of freedom. The second part consists of an electronic and electromechanical equipment for automatic tracking of the intensity of the electromagnetic radiation incident on the photovoltaic panel and a set of actuators, controlled by a microcontroller, that move the base of the panel in the direction of the maximum intensity of radiation. The booklet that describes the physical foundations of the phenomena involved with the experimental system built consists of a compilation, in pdf format, of the product application classes which have animations and applets related to the basic principles of electromagnetic waves, semiconductor materials, the photoelectric effect and the photovoltaic effect. The didactic set is presented as an innovation of digital information and communication technologies concretized in an educational product to help experimental physics classes in high school.
