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.
Working principle of Photovoltaic Cell is similar to that of a diode. In PV cell, when light whose energy (hv) is greater than the band gap of the semiconductor used, the light get trapped and used to produce current.
As we dive into the detailed world of the construction and working of solar cell, we need to see the parts and functioning of the solar cell. Individual solar cells are the main parts of photovoltaic modules. They are also known as solar panels. Solar cells are photovoltaic but their energy source is sunlight or artificial light.
Basics of solar cells A solar cell is an opto electronic device. It can directly convert light into electricity (Fig. 1.2). power. This process requires firstly the generation of electron and hole carrier s by the absorption of incident photons. Secondly, the collection of these carriers by the p-n junction,
Solar cells exploit the optoelectronic properties of semiconductors to produce the photovoltaic (PV) effect: the transformation of solar radiation energy (photons) into electrical energy. Note that the photovoltaic and photoelectric effects are related, but they are not the same.
These four parameters: Jsc, Voc, FF, and ŋ are the key performance characteristics of a solar cell. All of these should be defined for particular illumination conditions. The Standa rd Test around the sides of the device.
