Summary / Abstract: The tremendous growth of the photovoltaic (PV) market and production capacities during the past years encourages the development of recycling processes of end of life modules and PV industry wastes. To explore and develop industrial solutions for such recycling issues, the European project CABRISS was launched. The goal of this project is essentially focused on the salvage of valuables metals such as silver (Ag) and indium (In) but also the silicon (Si) coming from PV wastes. In parallel, the development of these recycling processes will help feeding advanced reflections on how to create a circular economy integrating PV wastes recovery back into the market. During the last PVSEC conference, some works were presented on the recycling of broken solar cells (or at earlier stages of the solar cell fabrication) and the production of recycled Si (Re-Si) feedstocks [1]. Several p-type Re-Si ingots with different crystallinities (multi-crystalline (mc) and mono-like (ml)) were then successfully grown. Recently, these ingots were sliced into 156 mm² wafers for further material studies and solar cells fabrication.
