<p>The rapid growth of solar energy adoption has led to an increasing demand for effective recycling technologies for silicon-based photovoltaic (PV) solar panels, which are expected to reach significant end-of-life volumes in the coming years. This literature review critically examines the current challenges and opportunities associated with the recycling of silicon PV panels. Key challenges include the complex material composition of solar panels, the economic viability of recycling processes, and the environmental impacts of improper disposal. Technological barriers, such as inefficient extraction methods and limited recovery rates, hinder effective recycling efforts. Conversely, advancements in recycling technologies, such as hydrometallurgical and pyrometallurgical processes, present opportunities for improved material recovery and reduced environmental footprints. The integration of circular economy principles into designing and manufacturing solar panels is also explored as a pathway to enhance recyclability. Furthermore, policy frameworks and industry collaborations are highlighted as critical components for fostering innovation in recycling practices. This review aims to provide a comprehensive understanding of the current state of silicon PV panel recycling, identify key areas for future research, and propose strategies to overcome existing challenges, ultimately contributing to a more sustainable solar energy ecosystem.</p> Graphical Abstract <p></p>
