Customer ServiceA solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. A solar cell is basically a p-n junction diode.
All the aspects presented in this chapter will be discussed in greater detail in the following chapters. The working principle of solar cells is based on the photovoltaic effect, i.e. the generation of a potential difference at the junction of two different materials in response to electromag-netic radiation.
Construction Details: Solar cells consist of a thin p-type semiconductor layer atop a thicker n-type layer, with electrodes that allow light penetration and energy capture.
Material Characteristics: Essential materials for solar cells must have a band gap close to 1.5 ev, high optical absorption, and electrical conductivity, with silicon being the most commonly used.
Sufficient solar energy strikes the earth each hour to meet worldwide demands for an entire year. The n-type layer of a PV cell is very thin to allow light penetration into the p-type region. The thickness of the entire cell is actually about the thickness of an eggshell.
The coating layer in a solar cell is a flexible and thin layer of ethylene-vinyl acetate (EVA) material applied to the surface of the battery’s photodiode. The sheet is made of a thermoplastic polymer, ensuring: Insulation properties. Additionally, the coating layer provides a strong connection between tempered glass and solar elements.
