AI Technical Summary
Technical Problem
The black solder strips or busbars of existing photovoltaic modules are prone to problems such as miscoating, delamination, cracking, and high cost during the coating preparation process.
Method used
A blackening solution containing sulfides, carboxyl compounds, and oxygen-containing polar solvents is used to perform an in-situ sulfidation reaction on the non-welding surface of the solder strip or busbar, generating a black lead sulfide and/or tin sulfide blackening layer to form a uniform blackening layer.
Benefits of technology
This technology makes it less prone to delamination or cracking when the welding strip or busbar is bent, improves light absorption, reduces costs, and the blackening layer is environmentally friendly and free of heavy metal pollution.
