The central semiconductor parameters that determine the design and performance of a solar cell are: i) concentrations of doping atoms, which can be of two different types; donor atoms which donate free electrons, ND, or acceptor atoms, which accept electrons, NA. The concentrations determine the width of a space-charge region of a junction.

3.2.1 Absorption and Energy Conversion of a Photon. When light illuminates a solar cell, the semiconductor material absorbs photons; thereby, pairs of free electrons and holes are created (see Fig. 3.1).However, in order to be absorbed, the photon must have an energy E ph = hν (where h is Planck''s constant and ν the frequency of light) higher or at least equal to …

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron vacancy or "hole" is created.
