At the heart of PV systems, a solar cell is a key component for bringing down area- or scale-related costs and increasing the overall performance.
Crystalline silicon (c-Si) PV modules, the first generation of solar cells, occupy the largest market share due to their mature technology and high photoelectric conversion efficiency . Correspondingly, the recovery of EoL c-Si PV modules has attracted the most attention of related scholars [ 15, 16 ].

The most relevant methods for the production of crystalline silicon for PV applications are the Czochralski method for monocrystalline silicon and directional solidification method for multicrystalline silicon. We study the fabrication of these two types of crystalline silicon in the next sections.
For crystalline, silicon-based PV cells, the following chemical treatments were performed: removal of the metal coating, followed by the removal of AR coating and n-p junction byetching. The standard acid etching mixtures contain high amounts of toxic nitrogen oxides, fluorides and different silicon species, which require costly disposal measures.
5.1. Silicon wafer fabrication The vast majority of silicon solar cells in the market are fabricated on mono- or multicrystalline silicon wafers. The largest fraction of PV modules are fabricated with crystalline solar cells today, having multicrystalline cells been relegated to a few percent of market share, followed by thin film-based cells.
The fabrication of this solar cell design comprises these general steps: a. Surface preparation by cleaning and texturing to minimize light reflection. b. Diffusing an n-type dopant into the p-type wafer to form a pn junction. Back passivation through a BSF formed by Al diffusion.
Hence, the gettering process further purifies the silicon wafer. This gives room for using lower quality (and lower cost) silicon material to fabricate the wafers, knowing that they will be further purified during the solar cell fabrication.
Constant-source and constant-dose diffusion are the most common in silicon solar cell fabrication. Typical processes to form the pn junction in silicon solar cells comprise two steps: A pre-deposition process with a constant source, such as process A defined previously, to introduce the desired dose of dopant impurities in the wafer surface.
