Proceedings of International Conference on Hybrid and Organic Photovoltaics (HOPV22)

Patterned silver nanostructures such as nanowires, nanoparticles and films patterned with periodic arrays of apertures are of a great interest for a range of applications due to fast progressing miniaturisation of technology and increased interest in cost-effective and off-grid, portable, wearable, and flexible devices. For application in organic photovoltaics (OPVs) silver films patterned with a periodic array of sub-wavelength apertures are of interest as plasmon-active light trapping electrodes.1,2 However, current industrial methods for the fabrication of such structures over the large areas needed for practical application in OPVs are too costly to be economically viable and often involve the use of thick layers of photoresists and/or toxic metal etchants. Here we apply a new, potentially very low-cost method for the fabrication of light-catching silver electrodes based on the condensation coefficient modulation; a method recently developed by our group.3,4 We show that the key to achieving such highly selective silver deposition is the use of perfluorinated polymethacrylate film deposited by micro-contact printing. The performance of these electrodes as both the reflective and transparent electrodes will be reported.

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.
