Computational studies on electronic structures of materials used in perovskite solar cells (PSCs) are reported. The main concern in this presentation is on chemical characteristics of metal-halide perovskite compounds, organic hole-transport materials, and their interface because carrier transports across these materials are considered to be the bottleneck in PSCs. We perform first-principles calculations at the density-functional-theory level and apply some cheminformatics methods in order to have better understanding and prediction of their chemistries. In the presentation, we will discuss the following four issues: (1) some electronic properties calculated by the DFT method can be used as descriptors of hole mobility in statistical analyses. Based on the informatics study, we suggest some organic compounds for efficient hole transport. (2) Pb-free perovskite-type compounds with a reasonably wide band gap are suggested on the basis of our own materials design, which is justified by the DFT calculations. (3) The rate constant of the photo-induced hole injection at interface are evaluated and is shown to be surface dependent. (4) Surface fabrication of metal halide perovskite by pi-conjugated molecules is expected to be useful to enhance carrier transport by removing harmful effects by lattice defects beneath the interface.
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.
