Customer ServiceChapter 4. The working principle of all today solar cells is essentially the same. It is based on the photovoltaic effect. In general, the photovoltaic effect means the generation of a potential difference at the junction of two different materials in response to visible or other radiation. The basic processes behind the photovoltaic effect are:
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.
Here, LD is the Debye length (17) L D = ε k B T q 2 N B where ε is the static dielectric constant, and N B = N A N D N A + N D In an ideal p–n junction solar cell the junction (or depletion) region serves as a lossless mechanism for extracting and separating the minority carriers from the quasi-neutral regions—the base and the emitter.
In the application to solar cells a full understanding of the problem is hindered further by the polycrystalline nature of the materials and frequently the presence of more than two layers that need to be considered in the analysis. Figure 13.
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.
The band diagram corresponds the usual situation encountered in CdTe and CIGS solar cells where an n-type wide-gap window and a p-type emitter are the most common arrangements. Similarly to the p–n junction the built-in potentials Vbi (A) and Vbi (B) on the two sides of the junction can be determined by solution of the Poisson equation (see Eq.
