Abstract

Perovskite solar cells (PSCs) have emerged as a promising option for solar energy generation. However, it is essential to consider the environmental impact of these innovative photovoltaic (PV) technologies as the industry moves towards commercialization. Researchers are currently exploring ways to recycle PSCs to recover valuable materials and reduce their environmental impact at the end of their life. To ensure the sustainability of PSCs, this study evaluates and compares the environmental impacts of five recently developed recycling approaches. The Tool for Reduction and Assessment of Chemicals (TRACI) method was utilized to measure environmental impacts in categories such as acidification (kg SO2-eq.), ecotoxicity (CTUe), eutrophication (kg Neq), GWP (kg CO2-eq), human toxicity (CTUh), cancer and non-cancer, human health particular air (kg PM2.5-eq), ozone depletion (kg CFC11eq), and smog (kg O3-eq). The results indicate a novel recycling approach using potassium iodide (KI) solution has lower environmental impacts. In contrast, processes involving butyl-amine (BA), chlorobenzene, and dimethylformamide (DMF) have significantly higher environmental impacts arising from 1 to 3 times higher than the reference method, except for ozone depletion, ~7 to 10 times higher than the reference.

Comparative Life Cycle Assessment Of Recycling Processes For Perovskite Solar Cells
