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.

The efficiency of a solar cell, defined in Eq. 1.1 of Chapter 1, is the ratio between the electrical power generated by the cell and the solar power received by the cell. We have already stated that there must be a compromise between achieving a high current and high voltage, or, equivalently, between minimizing the transmission and thermalization losses.
Phosphoric acid fuel cells use liquid phosphoric acid as an electrolyte— the acid is contained in a Teflon-bonded silicon carbide matrix—and porous carbon electrodes containing a platinum catalyst. The phosphoric acid fuel cell (PAFC) is considered the "first generation" of modern fuel cells. It is one of the most mature cell types and the
These cells have working temperatures in the range of 150℃ to 200℃. Because of the non-conductive nature of phosphoric acid, electrons are forced to travel via an external circuit to the cathode.
