For GaAs-based solar cells, performance can also be tuned by layering, where one solar cell can contain up to eight thin layers, each absorbing light at a specific wavelength. Such photovoltaic cells are called multi-junction or cascade solar cells. They use tandem fabrication, so they can also be found under the name tandem cells. Each layer ...
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.
For GaAs-based solar cells, performance can also be tuned by layering, where one solar cell can contain up to eight thin layers, each absorbing light at a specific wavelength. Such photovoltaic cells are called multi-junction or cascade solar cells. They use tandem fabrication, so they can also be found under the name tandem cells.
As widely-available silicon solar cells, the development of GaAs-based solar cells has been ongoing for many years. Although cells on the gallium arsenide basis today achieve the highest efficiency of all, they are not very widespread. They have particular specifications that make them attractive, especially for certain areas.
First, absorption of light generates an electron–hole pair. The electron and hole are then separated by the structure of the device—electrons to the negative terminal and holes to the positive terminal—thus generating electrical power. This process is illustrated in Fig. 1, which shows the principal features of the typical solar cells in use today.
The I – V characteristics of an ideal solar cell complies with the superposition principle: the functional dependence (1) can be obtained from the corresponding characteristic of a diode in the dark by shifting the diode characteristic along the current axis by Iph (Fig. 4). Figure 4. The superposition principle for solar cells. 2.2.
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.
