Free-electron effects on the optical absorption of the hybrid perovskite CH3NH3PbI3 from first principles

Hybrid organic-inorganic perovskites, such as methylammonium lead tri-iodide (MAPbI3), are interesting candidates for efficient absorber materials in next-generation solar cells, partly due to an unusual combination of low exciton-binding energy and strong optical absorption. Excitonic effects in th...
