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.
In Chapter 3, the structures and types of solar cells are summarized, and general aspects of the working principles of solar cells are explained. Chapter 3 also contains a comparison of the solar cells in regards to their efficiencies.
This is the case for solar cells, in which electrons need to be able to exit the n side of the cell and holes need to be able to exit the p side (this will be thoroughly analyzed in Section 3.4). If the flow of the majority carriers is also blocked by the passivation layer, the solar cell cannot generate any photocurrent.
If the flow of the majority carriers is also blocked by the passivation layer, the solar cell cannot generate any photocurrent. An effective way to achieve the desired carrier selectivity (to block the minority carriers but allow the majority carries) is the use of a doped layer.
However, it is required for many semiconductor devices that the passivation layer allows the flow of majority carriers. This is the case for solar cells, in which electrons need to be able to exit the n side of the cell and holes need to be able to exit the p side (this will be thoroughly analyzed in Section 3.4).
