Photovoltaic technologies are pivotal in decarbonizing global energy systems. Hereby, halide perovskite solar cells (PSCs), alongside silicon solar cells, have emerged as a promising solution for large-scale solar energy production due to their exceptional optoelectronic properties, solution processability and rapid efficiency improvements over the past two decades [1], [2].
To ensure sustainable deployment, addressing the end-of-life management of PSCs is critical to avoid environmental waste. Our research group has developed a closed-loop recycling process that dissolves all PSC layers, purifies the materials, and enables their reuse [3]. However, in practical applications, PSCs must be encapsulated to shield them from environmental factors and withstand thermal and mechanical stresses. Therefore, the development of recyclable encapsulation technologies is equally essential to maintain the sustainability of the entire lifecycle of PSCs.
This poster presents our latest research on the recycling of encapsulated PSCs. We explore various encapsulation designs and materials to enhance the durability and performance of PSCs. Our findings include degradation behavior under heat and humidity, and the efficiency of different encapsulation strategies. We also detail our recycling process, which involves removing encapsulants using a hot wire method, cleaning glass substrates, and initial steps for reusing perovskite materials. These advancements contribute to a sustainable, circular approach for PSC technology.
