摘要: The growing demand for energy combined with the scarcity of non-renewable sources has led to research alternative capable replacing traditional ones least environmental impact. Among these alternatives, solar is very important, since it a virtually inexhaustible source and generates relatively small impact compared other generation sources. collection its conversion into thermal or electrical only possible photovoltaic panels. These panels have limited lifespan 20 -25 in average will eventually be replaced by new thrown away. Thus, near future, large amounts modules become electronic waste. In order retrieve important raw materials, reducing production costs impacts, recycling such materials important. this paper, module components were characterized through visual inspection, x-ray fluorescence, dispersion spectroscopy atomic absorption spectroscopy. glass was identified as ordinary (soda-lime glass), which can reused without any previous treatment. metallic filaments tin-lead coated copper, recycled known pyrometallurgical processes. modules' cells made silicon had silver attached it. separated recovered chemical frames aluminium Moreover, different segregation methods been studied separate smallest Chemical, mechanical tested. Pyrometallurgical shown most promising results so far. A detailed description separations experiments' layouts given.
