Poseidon Solar Services Pvt Ltd is an exclusive silicon wafer and solar cell recycling facility focused on the solar PV industry. The company recovers all types of silicon and solar cell raw material bringing disposed and dead material back to the value chain in a professional recycling way.

Broken Solar cells

Poseidon processes broken solar cells to remove the coatings for reuse and re-melting. The process involves chemical etching removing all contaminants. The diffusion layer is also removed until the material is crucible ready. The material is sample tested for resistivity to confirm the removal of the diffusion layer, packed and shipped. The following are the different categories of broken cells that we process:

Type of material	Before process	After process (Crucible Ready)
Broken cells with until diffusion and SiN coated
Broken cells with print grid up to dryer / non fired
Broken cells after metallization from fire oven

All of the above cleaned wafers can be used directly to make solar-grade ingots.

Zero Power cells

Zero Power Cells are defined as cells that deliver no power or fail the specification for power output. Poseidon processes zero power cells to be directly used for cell making. This can be substituted instead of expensive wafers. The processing at Poseidon eliminates the subsequent energy consuming steps of melting, ingoting and wafering. The removal of coatings and the diffusion layer is confirmed by 100% resistivity check.
