Another promising source of green energy is from the sun, solar energy harvested by solar cells. We are currently studying phonon and electron transport in hybrid organic-inorganic perovskites, using molecular dynamics, lattice dynamics, as well as density functional perturbation theory. Our primary concerns are three-fold: i) the displacive structural phase transition; ii) the anomalous transport physics, such as the dependence of thermal and electrical properties on structure; and iii) polaron formation and polaronic effects.
