TL;DR: In this paper, density functional theory calculations of both the diffusion barriers and the formation energies for native defects (VI+, MAi+, VMA-, and Ii)-were performed for CH3NH3PbI3-based solar cells.
Abstract: CH3NH3PbI3-based solar cells have shown remarkable progress in recent years but have also suffered from structural, electrical, and chemical instabilities related to the soft lattices and the chemistry of these halides One of the instabilities is ion migration, which may cause current–voltage hysteresis in CH3NH3PbI3 solar cells Significant ion diffusion and ionic conductivity in CH3NH3PbI3 have been reported; their nature, however, remain controversial In the literature, the use of different experimental techniques leads to the observation of different diffusing ions (either iodine or CH3NH3 ion); the calculated diffusion barriers for native defects scatter in a wide range; the calculated defect formation energies also differ qualitatively These controversies hinder the understanding and the control of the ion migration in CH3NH3PbI3 In this paper, we show density functional theory calculations of both the diffusion barriers and the formation energies for native defects (VI+, MAi+, VMA–, and Ii–) an

TL;DR: In this paper, the effects of nano-particle oxide fillers including TiO2, SiO2 and Al2O3 have been shown to have a significant affect on the properties of polymer electrolytes, especially those based on polyether-lithium salt systems.
