- <p>Photovoltaics (PV) is one of the most important renewable energy. During the production of Si-based<br>PV panels, large resource flows are generated, and many waste materials are generated. The challenge for recycling is<br>connected to the material properties: The composition, purity and morphology will determine how the current waste<br>should be processed in order to realize the potential value. We have therefore performed a waste inventory for three<br>important material flows occurring from monocrystalline silicon ingot and wafer manufacturing in the PV production<br>value chain: Si kerf from sawing of wafers, silica from crucibles used in CZ-Si ingot pulling and graphite from CZ<br>crystal growth furnaces. A series of characterization and analysis methods, have been used to investigate the chemical<br>composition, phases, size and morphology etc. of the three waste materials. Possible contamination sources were<br>discussed. The waste inventory results give an overview of the materials quality and property, and their potential for<br>recycling and re-use in the PV section and other application fields</p>
