Solar energy conversion plays a very important role in the transition to ore suitable energy system. In this sense, so many materials have been proposed to drive artificial photosynthesis, most of them based on inorganic semiconductors, and the achievements performance continue every day. However most of these materials presents well known short comings such as low light absorption, fast charge recombination, and lack of tunability which limiting their efficiency.[1] The use of conjugated Porous Polymers (CPPs) and their hybrid thereof open the door to multitude of possibilities when it comes to select and design of suitable photocatalyst. [2] Thus our group has been pioneering in the use of hybrid based on inorganic semiconductor and CPPs for hydrogen production and CO2 photoreduction processes[3]. However, when we tried to translate the acquired knowledge to photoelectrocatalysis devices we found difficulties related with the processability of this kind of hybrid materials. In order to design photoelectrocatalysts the main premise is to develop thin film photoelectrodes. But the CPPs synthesized by bulk techniques are big particles (from micrometres to millimetres) which the processing as thin films with enough optical and electrical quality is not possible. In this talk we will show our advance in the implementation of 1) high throughput microfluidic techniques through miniemulsion process; 2) electropolymerization; as well as 3) interfacial synthesis to the synthesis of nanostructured CPPs and how this is a key aspect to improve their performance in the energy field.

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.
