CH3NH3PbX3 perovskites have attracted significant attention as absorber materials for solar light harvesting, reaching power conversion efficiencies above 20%. Although there is a prompt evolution of the cell efficiencies, the understanding of basic properties of these semiconductors is still ongoing. Important device operation related questions still need to be answered: the hysteresis behavior, i.e., the difference of the performance between the two voltage directions when performing a current–voltage measurement, and progressively more attention is focused on the role of ions or vacancies migration under an electrical field. The magnitude of the hysteresis seems to be influenced by the n-type interlayer contact, with the most significant observed hysteresis in devices containing TiO2.
We have conducted measurements on perovskite solar cells, comprised of different metal-oxide (MO) electrodes, as the n-type contact. The significance of the selected MO is observed, since the MO – Perovskite interface is affected, especially upon illumination. Under illumination the dielectric constant of the perovskite changes dramatically, thus forming the effect at the MO – Perovskite interface. This effect is mainly influenced by four parameters: the dielectric constant of the MO, the existing electrical field across the interface, the thickness of the MO and the illumination intensity.
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.
