Desenvolvimento de um piranômetro baseado em componentes semicondutores

Abstract

This master of science thesis was developed from the idea of research and the production of a pyranometer of easy construction and low cost. This work presents research to develop a sensor in order to quantify the intensity of solar radiation incident on the earth's surface. The main component used is a photodiode which is constructed by two pellets of different semiconductor crystalline solids, encapsulated by an electrically insulating and transparent to the wavelength of the operating radiation material. The methodology used was to compare the measures of the developed prototype and considered standard pyranometer. This comparison was obtained by estimating the statistical parameters of the readings of photoelectric current generated by using a prototype, spectrally selective semiconductor device, which operates in the wavelength range around CMP3 consideret pyranometer model. The prototype was stable in its final stage of development, proving to be of viable production as a tool for low cost to obtain experimental data on the intensity of solar radiation.
