The aim of this work is to determine the best combination of parameters for the recycling of silicon from end-of-life solar cells. A chemical etching in hot sodium hydroxide solutions is the proposed treatment for the removal of the back-surface field and the emitter.

Abstract
The aim of this work is to determine the best combination of parameters for the recycling of silicon from end-of-life solar cells. A chemical etching in hot sodium hydroxide solutions is the proposed treatment for the removal of the back-surface field and the emitter. The etching kinetic has been studied on the back side of the cell. The best combination of time, temperature and solution concentration for the process is proposed. Then, the time when the emitter is removed has been studied too.File in questo prodotto:
