As the amount of photovoltaic (PV) modules installed around the world increases, the amount of end-of-life PV modules is also expected to increase. In view of this prospect, studies on a method of processing end-of-life PV modules are in progress. The most popular existing method of disposing of end-of-life PV modules is incineration. Glass and solar cells are often broken during this process. Methods such as chemical and heated cutter are being studied to recover the PV module components in an unbroken state. In this study, the transparent conducting oxide (TCO) delamination phenomenon existing in thin-film solar cells was applied to a silicon PV module to try to separate the encapsulant and glass. The fluorine-doped tin oxide (FTO) thin film was used as a sacrificial layer between the glass and the encapsulant. The sacrificial layer was delaminated by applying voltage and heating to the module, and as a result, it was confirmed that the glass and the encapsulant were separated.
