Solar cells converts the solar photons energy into electrical energy. The first solar cell was realized in 1954 at Bell Laboratories. The functioning principles of this first generation solar cells are based on a p-n homojunction realized in a bulk semiconductor (Silicon or GaAs). Figure 3.1 depicts the charge carriers’ distribution and band diagram levels before and after junction formation.
