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.
At the heart of a solar panel’s ability to generate electricity is the photovoltaic (PV) effect. Discovered in 1839 by French physicist Edmond Becquerel, the PV effect is the process by which solar cells within the panel convert sunlight into electricity.
The back of the panel is a solid backing material, and the entire assembly is framed in metal, providing structure and the ability to mount the panel. The assembly of solar cells into panels is a precise and careful process that aims to maximize the efficiency and durability of the final product.
Working Principle: The working of solar cells involves light photons creating electron-hole pairs at the p-n junction, generating a voltage capable of driving a current across a connected load.
The circuit allows the electrons to flow to the electron-poor back of the cell from the electron-rich front of the cell. Photovoltaic panels are oriented to maximize the use of the sun’s light, and the system angles can be changed for winter and summer. When a panel is perpendicular to the sunlight, it intercepts the most energy.

Experiments with PV Cells
Solar energy can be part of a mixture of renewable energy sources used to meet the need for electricity. Using photovoltaic cells (also called solar cells), solar energy can be converted into electricity. Solar cells produce direct current (DC) electricity and an inverter can be used to change this to alternating current (AC) electricity.

Working Principles of a Solar Cell
Solar cells need to absorb most of the incoming light to be efficient, and they must be thick enough to do so. For this reason, solar cells made of indirect-bandgap materials, such as silicon, are thicker than solar cells made of direct-bandgap materials, such as gallium arsenide. Nonetheless, very low thicknesses suffice to absorb most of the ...
