We calculate electron-phonon coupling coefficients using density functional perturbation theory for harmonic systems, and treat anharmonic ones using a combined ab-initio molecular dynamics and excited-state electronic structure approach. These interactions are used to understand the thermal and dissipative effects on electrons far from the ground state. Recent work includes the behavior of hot carriers in perovskite solar cells, and the generation of anomalous photocurrents from phonon scattering.
