Proceedings of International Conference on Perovskite Thin Film Photovoltaics and Perovskite Photonics and Optoelectronics (NIPHO20)
Publication date: 25th November 2019
Organic-inorganic metal halide perovskites have drawn considerable attention due to their outstanding performance as semiconductors in solar cells and light-emitting diodes. [lm1] Besides their use as the active layer in such devices, the relatively high charge mobility can be exploited using perovskites as thick transport layers in organic optoelectronics. This new application is still rather unexplored, and limited to vacuum deposited multilayer devices. Light-emitting electrochemical cells are unconventional light-emitting devices based on a single organic semiconducting layer. The presence of mobile ions in the active materials assist charge injection and transport, allowing for a simple device architecture. In this work we present a proof of concept demonstration of perovskite films operating as charge transport layers in combination with light-emitting electrochemical cells. We combined the inorganic wide band gap perovskite CsPbBr3 with polymer semiconductors such as Super Yellow or Red F and studied the device lifetime and luminous efficiency at different current density and for various device layout. Photophysical measurements [lm2] have been carried out in order to establish whether the perovskite layer contributes to the electroluminescence or provides non-radiative deactivation paths. Finally, the performance of the device has been optimized by varying the thickness of the perovskite hole transport layer and of the polymer film.
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.
