Production process of epoxy board photovoltaic modules

How are thin film PV modules made?

Thin film PV modules are typically processed as a single unit from beginning to end, where all steps occur in one facility. The manufacturing typically starts with float glass coated with a transparent conductive layer, onto which the photovoltaic absorber material is deposited in a process called close-spaced sublimation.

How a photovoltaic module is assembled?

The assembly of photovoltaic modules consists of a series of consecutive operations that can be performed by automatic machines dedicated to optimizing the single production phases that transform the various raw material in a finished product.

Why should you learn photovoltaic module production process?

By understanding the photovoltaic module production process and to learn which machines are involved in the production of a module, gives you the knowledge to understand the points that are delicate and fundamental for the production helping you in the choice of a reliable and high-quality product.

How a photovoltaic cell can be integrated into a production line?

Some of this equipment can be integrated into the production line according to the wished level of automation. The photovoltaic cells are placed in a piece of equipment, called solar stringer, that interconnects the cells in a series by soldering a coated copper wire, called ribbon, on the bus bar of the cell.

How are photovoltaic absorbers made?

The manufacturing typically starts with float glass coated with a transparent conductive layer, onto which the photovoltaic absorber material is deposited in a process called close-spaced sublimation. Laser scribing is used to pattern cell strips and to form an interconnect pathway between adjacent cells.

How to install a photovoltaic module?

The process is done by attaching the box with a suitable silicone or glue on the back sheet of the module and by making the electrical connection between the bus ribbon prepared before the lamination and the cables of the junction box. At the inside of the box, you can find by-pass diodes that protect the photovoltaic module when operating.
