Anderson localization is not only interesting from a scientific point of view, but also has been proposed to play a critical role in materials that can be used for the harvesting and efficient use of energy. Combining two recently developed methods, the effective disorder Hamiltonian method and the typical medium dynamical cluster approximation, has opened the door to investigate localization in such energy materials with first principles simulations. In this talk, I will present our recent studies of localization in the diluted magnetic semiconductor Ga(Mn,N) and the intermediated-band photovoltaic Ti-doped Si.
