The search for the reduction of costs implementation renewable energies implies in optimization parameters manufacturing processes consolidated technologies. Among these technologies are solar collectors composed absorber films characterized by high absorption spectrum range corresponding to radiation and low emittance infrared range, allowing an increase collector's operating temperature (300 700°C). present work produced selective surfaces based on black chrome stainless steel substrate...
The availability of fossil resources decreases over the years, constituting a problem that needs to be properly treated. In this context, it is necessary exploration alternative and renewable sources energy, particularly use solar energy incident on planet. aim work examine feasibility application sugarcane bagasse ash as precursor material for obtaining an inorganic polymer will form absorber film in collectors medium high temperature. Through mechanical particle size separation its...
Selective surfaces have the function of absorbing strongly sunlight, while ideally losing little heat to environment via convection and radiation. The present study sought obtain a selective surface black chromium coated with an antireflective (AR) layer based on sugarcane bagasse ash using copper as substrate. From this electrodeposition parameters (time, working distance, voltage) well behavior were analyzed in order determine if AR provided increase absorption levels film. By means it was...
Solar thermal energy is one of the ways using solar radiation that can be applied to meet needs for heating. To achieve efficient photothermal conversion, selective surfaces are collectors absorb more and minimize heat loss. The present work produced absorber from black chromium electrodeposition on stainless steel substrate, main parameter evaluated was deposition time its effect optical morphological properties. In this sense, techniques characterization UV-Vis-NIR Spectroscopy, Infrared...
