A planetary emergency has arisen from the continued depletion of fossil fuels, producing green house warming and unprecedented environmental pollution. Future energy options for renewable and carbon-free sources will need to fill the terra-watt gap that will open up during the next few decades due to the growth of the world population. A promising development is the recent emergence of a new generation of low cost and highly efficient photovoltaic converters based on molecular sensitizers and perovskite pigments as light harvesters. Dye sensitized solar cells are meanwhile found applications as flexible light weight power supplies for portable electronics as well as electric power producing glass panels their market being presently in the multi-megawatt range. Perovskite solar cells (PSCs) [1] have directly evolved from DSCs. They have attracted enormous interest due to their low cost ease of preparation and ha certified solar to electric power conversion efficiency (PCE) exceeding already the performance polycrystalline silicon solar cells. Present efforts focus on scale up of the device size [2] and achieving operational stability [3]. The high photovoltage (Voc > 1.2 V) attained with these systems renders them very attractive for the generation of fuels from sunlight, e.g. by the splitting of water into hydrogen and oxygen [4] and the cleavage of CO2 into CO and 1/2 O2.

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.
