This current review article offers an extensive and thorough review of both primary and secondary treatment processes, including the top recycling processes (mechanical, thermal, and chemical), medium recycling processes, and bottom recycling processes adopted for recycling silicon PV panels.
Through extracting and refining silicon from decommissioned panels, manufacturers can reduce waste and optimize resource utilization, thereby contributing to a more sustainable solar energy ecosystem.
Electrostatic separation has an influence in most of the materials present in waste silicon photovoltaics. This process may assist in the recycling of waste PV.
Proper recycling and disposal of decommissioned PV modules is a practical requirement for the sustainable development of the country and industry. Crystalline silicon (c-Si) solar cells currently occupy 85%–90% of the market share, and some scholars have begun to seek the utilization pathways of the waste Si in and outside the PV industry.
However, technical challenges persist in the process of addressing the recycling and disposal of waste crystalline silicon PV modules. Numerous scholars have conducted extensive research, exploring methods such as pyrolysis, chemical treatment, and mechanical processing for recycling.
Projections suggest that e-waste from silicon PV panels may reach 60 to 78 million tonnes by 2050 (Song et al., 2023; Guinée, 2002), with environmental and health risks due to the presence of aluminum, silicon, lead, cadmium, and tin (Tan et al., 2022; Jain et al., 2022).
