6 Frequently Asked Questions about “How to extract substances from solar energy”
How to extract pure silicon from a solar cell?
To extract pure silicon from the solar cell, various chemical treatments have been used [4, 5, 8]. Hydrofluoric acid was the most common chemical used for separating silicon from the solar cell [4, 5]. However, the usage of hydrofluoric acid has to be eliminated as it is a highly toxic and corrosive chemical.
How to recover pure silicon and other materials from disposed solar cells?
This work is aimed at efficiently recovering pure silicon and other materials such as aluminium, silver, and lead from disposed solar cells using chemical treatments. Earlier, the pure silicon was recovered by treating the solar cells with hydrofluoric acid or mixture of hydrofluoric acid and other chemicals.
What is the use of recovered silicon in a solar cell?
The recovered silicon can be used for manufacturing new solar cell or electronic components such as diode, transistor, and microchip. The other materials present in solar cell such as aluminium, silver, and lead are recovered as aluminium hydroxide, silver chloride, and lead hydroxide, respectively.
Which material is used to recover pure silicon from inner solar cell?
Here, the recovery of pure silicon from inner solar cell is conducted. The solar cell mainly contains silicon (about 91.586% by weight) (Table 1). It also contains other materials such as aluminium at bottom layer, silver electrodes at top layer, and lead and antireflecting coating (Si 3 N 4) at top layer.
