Process flow of perovskite photovoltaic panel packaging line

The process flow of packaging lines for perovskite photovoltaic panels usually includes the following steps:

Substrate preparation:

Cleaning the substrate: Clean the impurities and pollutants on the surface of the substrate to ensure subsequent material adhesion and packaging quality.

Cutting and edging: According to product design requirements, the substrate is cut and edged to achieve the desired size and shape.

Electrode preparation:

Transparent electrode coating: Coating a transparent conductive oxide (TCO) film, such as tin oxide (SnO2) or indium tin oxide (ITO), on a perovskite film.

Metal electrode coating: Coating a metal electrode on a transparent electrode, usually using silver paste or copper paste.

Coating of protective layer:

Coating protective layer: Coating a protective transparent material on the surface of the electrode to improve the stability and durability of the device.

Encapsulation:

Backboard installation: Attach the backboard to the electrode to provide mechanical support and protection.
