Given the high complexity of the c-Si cell recycling, other useful materials such as glass, aluminum and silver seem more and more useful to improve the economic viability of recycling processes. Wang et al. [52] proposed a two-step heating process for the thermal delamination of PV modules. By using the process, the EVA could be burned out and the whole glass plate could be obtained without breaking and directly used again as the module component when the temperature was well controlled.
