Recycling Perovskite Solar Cells: A Holistic Approach to Environmental and Economic Sustainability
This study presents a highly efficient recycling method for perovskite solar cells, encompassing the recovery of materials from various layers of the cell components, including the perovskite layer, hole transport layer (spiro-OMeTAD), and electrodes. Through layer-by-layer recycling and multiple recycling rounds, the method achieves an electrode recycling rate as high as 96.8%. A comprehensive life cycle assessment (LCA) was conducted to analyze the environmental impact and economic benefits at different recycling frequencies, and the levelized cost of electricity (LCOE) was calculated. The results demonstrate that recycling significantly reduces environmental impact and enhances the economic competitiveness of perovskite solar cells.
