Proceedings of International Conference on Hybrid and Organic Photovoltaics (HOPV16)
Publication date: 28th March 2016
During the last few years, rapid emergence of organic-inorganic halide perovskites solar cells along with the ever-increasing efficiency has led to a new era of solar energy research. Lead based perovskite solar cells are central to the efficiency rise, however the toxicity of lead and the adverse effects to the environment must be of concern. In this work, three different bismuth-iodide based inorganic-organic hybrid compounds have been studied for their potential to be alternatives to lead-based perovskites in the solar cell. Specifically, [CH3(C5H5N)]4Bi2I10 with one-dimensional chain structure, (C5H6N)4Bi2I10 with one-dimensional chain structure, and (C5H7N2)3[Bi2I9]2 dimer have been prepared and studied. Their structures have been investigated with single crystal X-ray diffraction; electrochemical and optical properties have been characterized to assess their potential as light absorbers in solar cells. Furthermore, the band structures and orbital energies have been calculated, and spin-coating carried out to prepare thin films for potential low-cost manufacturing. Applications of these materials in solar cells will be discussed and could lead to promising future materials for lead-free third generation photovoltaics.
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.
