Proceedings of International Conference on Hybrid and Organic Photovoltaics (HOPV16)
Publication date: 28th March 2016
Organic-inorganic solar cells based on lead halide perovskites are drawing growing interest recently due to their high efficiency, low fabrication cost, and exhibit favourable optical and electronic properties such as strong optical absorption in the visible and ultraviolet spectrum. These properties are also highly desirable for many other optoelectronic applications, where organic-inorganic perovskites could once more lead to a step change in feasibility or performance. However, little in depth knowledge exists to date on what governs the behaviour of the emissive species in these materials. Recently, organometal halide perovskite have also shown promising applications as light-emitting materials due to the high photoluminescence (PL) quantum yield and transport of both electrons and holes. Charge recombination was proposed as the main mechanism for PL emission. PL provides important information about the excited state and charge dynamics that have also been investigated by transient absorption spectroscopy time-resolved terahertz, and microwave conductivity. In this work two perovskites systems has been studied, namely methylammonium lead bromide (MAPbBr3) and the mixed halide obtained by partial substitution with chlorine (CH3NH3PbI3-xClx) with various halide combinations studied via fluorescence microscopy (FM) coupled with an optical fibre spectrometer. This provides information on the local photoluminescence (PL) and allows us to map the surface of the films.
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.
