Proceedings of International Conference on Perovskite Thin Film Photovoltaics, Photonics and Optoelectronics (ABXPV18PEROPTO)
Publication date: 11th December 2017
We have studied the band aligmenent between cuprite (Cu2O) and perovskite CH3NH3PbI3 through density functional theory (DFT). The objective is to propose Cu2O as hole transport material for perovskite solar cells. Cu2O, or cuprous oxide, crystallizes in a simple cubic lattice with a six-atoms base, two copper atoms and six oxygen atoms. The copper atoms form a face-centered-cubic lattice and oxygen atoms are located on a body-centered-cubic sublattice. The perovskite CH3NH3PbI3 (methylammonium lead iodide) is known abbreviated as MAPI. In MAPI the cation A is methylammoniun, the cation B is lead and the halogen C is iodide.
Through quantum mechanical calculations of the electronic structure, using the Quantum ESPRESSO code [1], we aligned the bands of cuprite and perovskite with respect to the vacuum reference. The procedure consists in calculating the profile of the electrostatic potential at the crystal surface using the slab model. The position of the band edges with respect to the electrotatic potentials is obtained from a generalized DFT calcultion with a hybrid functional. Previously, several surface models were designed for both Cu2O and CH3NH3PbI3.

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
