"Cage Traps" for Perovskite Solar Pb Management

• Researchers from Zhengzhou University and Chinese Academy of Sciences have developed a new lead capturing technique for perovskite solar cells to mitigate Pb leakage and shield from external invasion, providing insights into green and sustainable industrial processes.

Researchers from Zhengzhou University and the Chinese Academy of Sciences have developed a novel lead capturing technique for perovskite solar cells by creating a biomimetic cage trap. The technique effectively mitigates Pb leakage and shields the cells from external invasion. The team's findings also provide insights into promoting green and sustainable industrialization of perovskite solar cells by establishing a sustainable closed-loop Pb management process based on four critical steps: precipitation, adsorption, desorption and recycling.

How Can Perovskite Solar Cells be Sustainably Managed?

• Design and implement adequate cell materials and device structures to reduce Pb leakage from cells
• Regularly monitor the Pb leakage of the cells and use appropriate mitigation measures
• Develop effective methods for Pb trapping and recycling
• Enhance cell stability and design efficient cell protection strategies
• Use renewable energy sources such as wind and solar to power production processes
• Ensure proper handling and disposal of all hazardous materials from the production process
• Implement safety measures and environmental regulations to protect workers and the public
• Promote the use of green energy technology to reduce the need for Pb-based materials in the solar cells
• Invest in research and development of alternative materials and technologies to replace Pb materials in the production of solar cells
