Cubic methylammonium lead iodide (MAPbI3) is one of the hybride perovskite materials that exhibit high energy conversion efficiency for photovoltaics. Using Quantum Espresso, we calculate the energy profile of MAPbI3 with the Methylammonium ion under different orientations within the cubic structure. Based on this energy profile we calculate the electron mobility as a function of temperature using the complex band method.
