Proceedings of September Meeting 2016 (NFM16)
Publication date: 14th June 2016
Sb based chalcogenides including Sb2Se3, CuSbS2 and CuSbSe2 represent a group of photovoltaic materials that are environmentally benign, relatively earth abundant and possessing attractive optoelectronic properties. In this presentation, the fundamental physical properties of these three compounds including their band gap, band position, defect chemistry, intrinsic and extrinsic doping and so on, will be first discussed as a rough evaluation for their potential as photovoltaic absorber materials. Then I will discuss hydrazine processed Sb2Se3, CuSbS2 and CuSbSe2 polycrystalline films and solar cells, and aqueous solution sprayed Sb2(S, Se)3 solar cells with special emphasis on the chemistry reaction involved in precusor dissolution and film formation. I will also briefly discuss vacuum processed Sb2Se3 solar cells with emphasis on the fabrication and characterization of the certified 5.6% device by rapid thermal evaporation. Key steps for device optimization, comparision between solution processing and vacuum processing, as well as perspective for the further optimization of Sb based chalcogenide solar cells will also be included in the talk.
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.
