The sun’s photons provide the largest source of energy on earth and its exploitation could help solve the energy crisis without being detrimental for the environment. Organic semiconductors, either polymers (usually electron donor) or small molecules (fullerene or non-fullerene acceptors), can be dispersed in water to provide human and environmentally-friendly processes for photovoltaics as alternative to classical options typically using toxic organic solvents. Concerning solar fuel production, Pinaud et al. have demonstrated by life cycle analysis that a colloidal system, in which the photocatalysts are in the form of nanoparticles dispersed in water, would be the cheapest technology to the production of H2.[1] Therefore there is an important need to study the formation of organic semiconducting nanoparticles and develop their use in these solar-technologies.[2]
In this communication, I will show what we have developed the 4 last years on this topic and more precisely the use of the Nanoprecipitation methodology to prepare the nanoparticles.[3] I will discuss its advantages and drawbacks and the Donnor/Acceptor morphologies that can be expected from nanoprecipitation. Through two systems, P3HT/PCBM and PTQ10/Y6 I will describe the incorporation of these dispersions as the medium for photocatalyzed hydrogen generation and as the active layer of photovoltaics cells.
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.
