The cells are very thin and fragile so they are sandwiched between a transparent
front sheet, usually glass, and a backing sheet, usually glass or a type of tough plastic.
This protects them from breakage and from the weather. An aluminum frame is tted
around the module to enable easy xing to a support structure.
The picture in Fig. 2.6 shows a small part of a Module with cells in it. It has a glass
front, a backing plate and a frame around it.
