The Working Principle of a Solar Cell In this chapter we present a very simple model of a solar cell. Many notions presented in this chapter will be new but nonetheless the general idea of how a solar cell works should be clear. All the aspects presented in this chapter will be discussed in greater detail in the following chapters.
In this chapter, the working mechanism for traditional silicon-based solar cells is first summarized to elucidate the physical principle in photovoltaics.
