Controlling and designing the crystallization process [1,2,3] of halide perovskites is key to their higher efficiency and long-term stability. Therefore, to achieve the required stability of record efficiency perovskite solar cells for their industrialization, it is essential to understand the atomic level fundamentals details of nucleation and growth process of perovskites on interfaces. Experimental techniques are often limited by their temporal and spatial resolution to get the atomic details of the formation process. Moreover, there could be electron beam-induced degradation and phase transitions due to the soft ionic nature of halide perovskites, therefore limiting the use of powerful techniques such as transmission electron microscopy to even achieve imaging of full crystallization pathway. In this talk, I will show how alternate methodology of molecular dynamics simulations [4,5] reveal the molecular details of the nucleation and growth process of halide perovskites on widely used interfaces such as TiO2, SnO2, NiO and commonly employed SAMs. To obtain precise results, I use quantum accurate machine learning potentials to simulate the all-atom dynamics of these multi-species complex systems and provide fundamental insights for designing reproducible experiments on interfaces. Apart from the growth mechanism, I will also show the molecular details of the buried interface and the origin of most detrimental defects, such as stacking faults [6], and nanovoids [7], and possible ways to eliminate these defects.
SNSF post-doc mobility fellowship
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.
