Organic semiconductors are an emerging class of materials with various optoelectronic applications and huge potential in supporting the development of greener electronics.In my talk, I will introduce sustainable routes to manufacture solution-processed organic photovoltaics. Most organic electronic devices are fabricated from halogenated and non-halogenated aromatic solvents, primarily due to the good solubility of the materials in the solvents and the ideal microstructure/crystallinity they are forming in those. For large-scale production and further commercialisation, this is a key limitation, as they can be carcinogenic or toxic to the human reproductive systems and negatively impact the environment. Here, I will show high-performing organic solar cells developed from novel, more sustainable organic semiconductors (in terms of less waste during synthesis and less energy consumption) as well as eco-friendly solvents. In particular, solvents derived from biomass have been explored for their application in delivering high-performing organic photovoltaics based on PTQ10:Y12 and FO6-T:Y12 with PCE > 14%.
Finally, I will discuss possible degradation mechanisms of the bulk heterojunction systems containing Y6 or Y12 as the acceptor, after degradation with indoor and outdoor light. A combination of electrical, morphological, and spectroscopic techniques were used to evaluate the degradation pathways of the OPVs.
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.
