Electronic properties of 2D and 3D hybrid organic/inorganic perovskites for optoelectronic and photovoltaic applications
We herein investigate theoretically both 2D and 3D Hybrid Organic/inorganic Perovskite (HOP) crystal structures based on Density Functional Theory (DFT) calculations and symmetry analyses. Our findings reveal the universal features of the electronic band structure for the class of lead-halide hybrids (R-NH3)nPbXm, where (n,m)=(2,4) and (1,3) respectively for 2D and 3D structures. Among those, t...
متن کاملPressure-induced dramatic changes in organic–inorganic halide perovskites
Organic-inorganic halide perovskites have emerged as a promising family of functional materials for advanced photovoltaic and optoelectronic applications with high performances and low costs. Various chemical methods and processing approaches have been employed to modify the compositions, structures, morphologies, and electronic properties of hybrid perovskites. However, challenges still remain...
متن کاملInterconversion between Free Charges and Bound Excitons in 2D Hybrid Lead Halide Perovskites
The optoelectronic properties of hybrid perovskites can be easily tailored by varying their components. Specifically, mixing the common short organic cation (methylammonium (MA)) with a larger one (e.g., butyl ammonium (BA)) results in 2-dimensional perovskites with varying thicknesses of inorganic layers separated by the large organic cation. In both of these applications, a detailed understan...

متن کاملDecreasing the electronic confinement in layered perovskites through intercalation.
We show that post-synthetic small-molecule intercalation can significantly reduce the electronic confinement of 2D hybrid perovskites. Using a combined experimental and theoretical approach, we explain structural, optical, and electronic effects of intercalating highly polarizable molecules in layered perovskites designed to stabilize the intercalants. Polarizable molecules in the organic layer...
