Semiconductor materials based on metal halide perovskites have attracted enormous attention in both research community and industry sectors in the past decade owing to their impressive performance demonstrated in the area of solar cells and other optoelectrical devices such as light emitting diodes, transistors etc. Currently the most widely used methods for synthesis of perovskite films is based on solution processing. The standard protocols of synthesis of the perovskite materials involves usage of large amount of hazardous, highly coordinating, aprotic polar solvent such as dimethylformamide (DMF) or carcinogenic N-methyl-2-pyrrolidone (NMP). The hazardous nature of these solvent raises concern for health, safety and environmental impact of these chemicals to humans and some of these solvent (e.g. DMF) has been banned to be used in manufacture in Europe. This restricts the commercial production of metal halide perovskite materials for various applications in practice.[1] Therefore it is highly critical to develop alternative sustainable solution processing for synthesis of metal halide perovskite using environmentally friendly, green solvent systems. In my talk, I will present our research on development of green processing methods for synthesis of metal halide perovskite using environmentally friendly solvent such as water, protic ionic liquids and biomass-derived solvent.[2] I will show that how the solvent system used in the material synthesis influence the physicochemical (morphology, optical and electrical) properties of the perovskite materials and the choice of precursor materials, which in turn determines the material’s performance in applications such as solar cells and light emitting diodes.
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.
