Proceedings of September Meeting 2016 (NFM16)
Publication date: 14th June 2016
My talk will focus on the processes of charge separation and recombination in organic bulk heterojunction and planar organic-inorganic hybrid perovskite solar cells. Experimentally it will be based around the use of transient absorption, photovoltage and photocurrent measurements on films and devices. In the organic solar cells, I will focus in particular upon the impact of film morphology, and particularly the presence of both pure and molecularly mixed domains, in influencing charge carrier dynamics and in particular the geminate recombination losses from bound polaron pairs. I will draw upon examples of studies from my group on polymer / fullerene blends and on blends employing a range of non-fullerene acceptors. I will then go on to consider the charge carrier dynamics in planar solar cells employing a methylammonium lead halide photoactive layer and PEDOT:PSS & PCBM charge collection layers. Finally I will consider the role of piezo- and ferro-electric fields in stabilising charge separation in light absorbing junctions and semiconductors.
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.
