Halide Perovskite can be prepared from solution methods at low temperature, and consequently they can be fabricated without large and expensive facilities, can be easily combined with other materials and efficiencies higher than 22% have been certified. However despites the unprecedentedly fast increase of the reported efficiencies, especially in the last four years, the working mechanisms of this kind of devices are not completely understood. As example the cells with the highest efficiency reported presents a thin TiO2 scaffold with a thicker perovskite capping layer, but it is not completely clear why this configuration provides such high efficiency with suppression of hysteresis effect. Transport, recombination, injection at the contacts or J-V curve hysteresis are strongly dependent on the cell configuration, as the use of scaffold, the perovskite and contact materials and also on the growth conditions. In this talk, I analyze the effect in the solar cell performance of different electron selective contacts and of surface engineering by the addition of self assembly monolayers. In addition, I show the effect of different scaffold configuration in the properties of the device by a systematic optoelectronic characterization, with especial attention to injection properties. I will also analyze the use of additives for the preparation of perovskite thin films.
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.
