Customer ServiceFrom an economic and productivity perspective in the recovery of silver from solar cells, the chemical leaching presents a viable technique. At present, the predominant method for leaching is the utilization of nitric acid, succeeded by precipitation with either NaCl or NaOH or by electrochemical refining.
Characterization of the solar cell before silver removal The success in separating silver electrodes without damage to the silicon wafer relies on the precise laser parameters used and the physical and geometric properties of the target material.
The AAS method is not recommended for general verification of the silver etching rate. Metallization is one of the key process steps to fabricate solar cells with high performance in a cost-effective way. Majority of photovoltaic solar cell manufacturing uses thick film screen print metallization with Ag containing paste to produce solar cells.
The successful removal and recovery of silver from the contact lines was analyzed through images obtained from optical microscopy, SEM, and EDS analysis. A laser-debonding approach to silver electrode recovery from solar cells is presented to address the critical need for efficient and eco-friendly recycling methods.
The effects of laser scanning on the solar cell surface and the removed silver lines were comprehensively characterized by involving scanning electron microscopy (SEM), optical microscopy, and energy-dispersive spectroscopy (EDS) images. The results confirm the successful removal of silver from the solar cells.
In this context, laser debonding is presented as a promising alternative for silver recovery from photovoltaic cells. Laser debonding is a technique that utilizes laser radiation to disintegrate the bonding at the interface between two materials.
