What are the basic processes behind the photovoltaic effect?

The basic processes behind the photovoltaic effect are: collection of the photo-generated charge carriers at the terminals of the junction. In general, a solar cell structure consists of an absorber layer, in which the photons of an incident radiation are efficiently absorbed resulting in a creation of electron-hole pairs.

What is the working principle of solar cells?

Chapter 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:

What are the loss mechanisms in single bandgap solar cells?

The two most important loss mechanisms in single bandgap solar cells are the inability to convert photons with energies below the bandgap to electricity and thermalisation of photon energies exceeding the bandgap, as illustrated in Fig. 3.1 (b).

What are the external parameters of a crystalline silicon solar cell?

Typical external parameters of a crystalline silicon solar cell as shown in Figure 3.1 are; Jsc of 35 mA/cm2, Voc up to 0.65 V and FF in the range 0.75 to 0.80. The conversion efficiency lies in the range of 17 to 18%. 3 M.A. Green, Solar Cells; Operating Principles, Technology and System Applications, Prentice-Hall, 1982.
