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.
