Influence of an aluminium concentrator corrosion on the output characteristic of a photovoltaic system

Abstract The climate changes observed over the last decades have been promoting a massive transformation on the energy sector, that is still, in truth highly dependent on fossil fuels. Renewable energies are a plausible alternative, because they have lower emissions of toxic gases in comparison with...
