This talk will present recent progress in the development of a new way to fabricate high performance transparent silver grid electrodes matched to the needs of organic photovoltaics: The electrodes have an average far-field transparency of 88%, a sheet resistivity of 6 ohm/sq, low (tuneable) surface roughness and can be fabricated on flexible plastic as well as glass. Electrodes of area 25 cm2 exhibit a less than 5% change in sheet resistance after 100,000 bending cycles through a radius of curvature of 6 mm. The silver grid is fabricated using a new iteration of a novel approach to patterning metal films developed in the Hatton laboratory, based on selective metal deposition by condensation coefficient modulation.[1,2] Using this approach embedded silver grid electrodes with micron-sized linewidth are realised, which is more than 10 times narrower than can be achieved using the conventional printing techniques of screen, inject and flexographic printing. This novel approach to grid electrode fabrication removes the need for harmful metal etchants and slow, chemical intensive electrochemical deposition steps. A performance of 10% power conversion efficiency in model OPV devices using these electrodes is comparable to that achieved using a conventional ITO coated glass electrode.
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.
