Solar energy is the most reliable, sustainable, and long-term source of energy that has the capacity to meet global electricity needs while providing environmentally friendly and grid-free electricity. There are three main requirements for any solar cell technology: low-cost components, high efficiency, and long-term performance. The advantages of the perovskite solar cells (PSCs) are the abundance of affordable and inexpensive materials that are solution-processable reducing the cost of manufacturing large-area panels. The era of PSCs began in 2009, when the power conversion efficiency (PCE) was only 3.8%, but due to the unique optical and electrical perovskite properties, PSCs quickly became one of the most researched solar technology. Rapid improvements in the device engineering and perovskite composition have made it possible to achieve a commercially attractive PCE exceeding 25%. Nevertheless, several challenges remain for the industrial application of perovskite solar cells. The biggest problem is considered to be the long-term stability of the light-absorbing three-dimensional (3D) perovskite compositions due to decomposition under atmospheric conditions. In this talk, novel perovskite compositions with the required hydrophobic properties and passivation strategies for the fabrication of PSCs to prevent direct contact with moisture, improve carrier transport and dipole moment leading to better device stability will be presented.

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.
