A front contact is typically applied to a solar silicon wafer through a process known as screen printing. In this process, a conductive paste containing metal particles is applied to the front surface of the wafer using a fine mesh screen. The paste is then dried and fired at high temperatures, causing the metal particles to fuse together and form a continuous conductive layer. This front contact acts as an electrode, allowing the collection and extraction of the generated electrical current from the solar cell.
A front contact is typically applied to a solar silicon wafer using a screen printing process. The process involves depositing a conductive paste onto the front surface of the wafer through a fine mesh screen. This paste consists of metal particles, such as silver or aluminum, mixed with a binder material. The screen is aligned with the wafer's surface, and the paste is forced through the screen using a squeegee, leaving a patterned layer of conductive material on the wafer. This front contact layer helps to collect and transport the electrical current generated by the solar cells.
A front contact is typically applied to a solar silicon wafer through a process known as screen printing. In this method, a special paste containing conductive materials such as silver or aluminum is spread onto the surface of the wafer using a mesh screen. The screen is carefully aligned with the wafer, and the paste is forced through the screen onto the wafer surface using a squeegee or a similar tool. This creates a pattern of conductive lines that make up the front contact. The paste is then dried and cured, forming a solid and durable front contact layer on the solar wafer.
