Proceedings of International Conference on Hybrid and Organic Photovoltaics (HOPV16)
Publication date: 28th March 2016
Dye-sensitized solar cells (DSCs) have been attracting a large amount of research interest in view of the extreme potential of converting solar and artificial light to electricity at low cost, and have recently reached a power conversion efficiency (PCE) record of 14.5% measured under the simulated AM1.5G sunlight, without using any conventional metal-complex dye. This glorious accomplishment embodies over 10 years intense studies on organic donor-acceptor dyes, single-electron redox shuttles, molecular-scale interface engineering, and device physics. Predictably, the development of more powerful metal-free organic dyes could well address the economic efficiency of a DSC, on primary account of copious raw materials and versatile synthetic methodologies. To further raise the PCE of a DSC with organic dyes, the realization of harvesting photons in the infrared region of the solar emission spectrum will be of paramount importance in the future explorations, mainly via narrowing the optical energy gap of a dye molecule. However, a reduction of HOMO/LUMO energy gap of a dye molecule is certainly concomitant with either a stabilized LUMO energy level or a destabilized HOMO energy level, or even both. These energetic changes are very much possible to exert unfavorable influences on the yields of generating long-lived charge carriers and thus lower external quantum efficiencies (EQEs). Additionally, the open-circuit photovoltage of a DSC is notably dominated by the thickness and pinhole defect of self-organized dye layers, lying spatially at the boundary of electron-transporting titania and hole-transporting redox electrolyte. In this talk, I will select several examples from our studies to address these issues.
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.
