Proceedings of International Conference on Hybrid and Organic Photovoltaics (HOPV23)

The presence of lead in high-performing hybrid perovskite-based solar cells remains a significant issue regarding commercial applications. On the other hand, materials based on Sb3+ as central atom are promising new candidates for low toxicity photovoltaic applications, as the same ns2 orbital configuration governs the frontier band character and semiconducting properties. Here, we showcase the thin film synthesis of 2D-MA3Sb2I9 and AgSbI4, circumventing common problems related to the use of antimony iodide as precursor. Furthermore, we demonstrate further synthetic and resulting electronic control of both these phases by heteroatom incorporation of Sn and Cu, leading to unique optical properties such as ultra-broad intervalence absorption. We critically assess the prospects of these compounds for optoelectronic applications by means of thorough theoretical and spectroscopic studies, revealing the presence of deep intragap states which govern the excitation behavior. Collectively, these results can help to achieve enhanced synthetic control and general understanding of the benefits and challenges associated with important lead-free perovskite alternatives.
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.
