This thesis deals with fundamental issues related to phonons in hot-carrier solar cells, athird generation photovoltaic technology. This concept aims at extracting photogeneratedcharge carriers before their reach a thermal equilibrium with the lattice, and exhibits a the-oretical efficiency close to thermodynamic limit. One of the main issue is to hinder carriercooling, which occurs through LO-phonon emission. In addition to the idea of screeningthe electron-phonon interaction, one approach consists in designing an absorber in which theLO-phonon has an intrinsic lifetime longer than what it is in conventional materials, en-hancing the rate of its reabsorption by the carriers. The LO-phonon decay and lifetimeis first investigated in semicond...
