However, end-of-life solar photovoltaic modules present the growing dilemma of solar waste management. A circular economy approach should therefore be applied to the solar industry due to the valuable materials contained within modules, and their upfront emissions and energy intensity. Solar module recycling has to date been delineated into three phases: disassembly, delamination, and extraction. Disassembly has been commercially established; delamination has experienced some progression with further development required to liberate the valuable solar cell material, while extraction has had more limited exploration, predominantly through a hydrometallurgical lens. Extraction via electrochemical methods, however, has received some recent attention in the literature with promising outcomes for both metal extraction and process electrification. Electrochemical approaches offer new methods for more advanced processing options. For example, high-temperature molten salt electrorefining has been investigated for metallurgical-grade silicon and could prove to be an effective process for recovering silicon.

In the IJP of PSCs, one important question is how to remove redundant excess solvent and facilitate the crystallization of the perovskite phase. Along with IJP, an antisolvent bathing is employed.
