Definition of Solar Cell Back Side Silver Paste
Definition of Solar Cell Back Side Silver Paste
Solar cell back side silver paste is a conductive material applied to the rear surface of photovoltaic cells during manufacturing. Its primary purpose is to facilitate electrical conduction, connect the cell’s internal components, and protect against environmental factors. Composed mainly of fine silver particles suspended in a binder, this paste ensures efficient charge collection and transfer, which are vital for the overall performance of solar panels.
Unlike front contact pastes, which are designed for light absorption, back side silver paste focuses on conductivity and durability. It forms a conductive layer that helps in collecting electrons generated within the solar cell and directing them toward external circuits. This layer also provides mechanical stability, preventing physical damage during installation and operation.
The use of silver in this paste is due to its excellent electrical conductivity and resistance to oxidation. As solar technology advances, formulations are optimized for lower costs and higher efficiency, but silver remains a preferred material due to its superior conductive properties.
How It Works
How It Works
Preparation of the Cell: The solar cell is cleaned and prepared for the application of the back side silver paste, ensuring a smooth, contaminant-free surface.
Application of Silver Paste: The paste is precisely printed or coated onto the rear surface of the solar cell using screen printing or other deposition techniques.
Firing Process: The coated cell undergoes a firing process in a furnace, which sinters the silver particles, creating a conductive and adherent layer.
Formation of Conductive Pathways: During firing, the silver particles fuse together, forming continuous electrical pathways that connect the cell’s internal layers to the external circuitry.
Encapsulation and Final Assembly: The finished cells are encapsulated with protective materials, sealing the silver layer and preparing the panel for deployment.
Electrical Functionality: The back side silver paste facilitates efficient charge collection, reduces resistive losses, and enhances overall energy conversion efficiency.
