Reducing reliance on coal-based grid electricity supply by using solar photovoltaic (PV) systems has become a viable global solution for energy issues. Furthermore, erratic electricity supply and the growing expense of producing electricity using fossil fuels can both be realistically addressed by PV technology .
Processes to recycle Si wafer from solar PV module The junction box, aluminium frame and cables have been separated mechanically which are attached with the help of adhesive glue (Silica gel). Mechanical separation is the only method to remove them without damage.
However, the International Renewable Energy Agency (IRENA) has reported that low quantities, limited recycling techniques, logistical challenges, and undeveloped material recovery markets have led to a high-cost, low-revenue scenario for global PV module recycling due to lack of efficient waste treatment methodologies and technologies .
For example, some SETO projects are working to replace the expensive silver contacts that carry electricity out of a solar cell with copper or aluminum. Several of our projects are also designing modules with new materials that make them easier to deconstruct. One approach uses sealants that can be dissolved without damaging other panel materials.
Making solar module recycling ubiquitous will require a combination of technology and policy innovation. To make a larger impact on reducing waste and other environmental impacts from solar technologies, actions need to be taken before a module is even made.
Conclusion This research provides a comprehensive analysis of End-of-Life (EoL) management for crystalline silicon photovoltaic (PV) panels, highlighting both challenges and opportunities. The results indicate sustainable options for managing PV panels beyond recycling.
