The majority of photovoltaic modules currently in use consist of silicon solar cells. A traditional silicon solar cell is fabricated from a p-type silicon wafer a few hundred micrometers thick and approximately 100 cm 2 in area.

A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. It is a form of photoelectric cell, a device whose
A solar cell is an optoelectronic device capable of transforming the power of a photon flux into electrical power and delivering it to an external circuit.

In modules, silicon solar cells are joined directly to copper ribbons and encapsulant layers, and indirectly to the front glass and the rear cover. Silicon shows a very low coefficient of thermal expansion (CTE) when compared to other materials (Fig. 3.8) ing a brittle material, the wafer requires a careful control of the maximum stress levels caused by thermomechanical loads.
In view of the destruction of the natural environment caused by fossil energy, solar energy, as an essential technology for clean energy, should receive more attention and research.
