Proceedings of 6th International Conference on Hybrid and Organic Photovoltaics (HOPV14)

Whether used as the top cell in a multi-junction stack or to drive electrochemical reactions, solar cells with high open circuit voltages (VOC) are an important tool in the efforts for sunlight energy harvesting. Achieving this requires a combination of a suitable energy band structure together with good charge collection kinetics. Solution-processed organic-inorganic lead halide perovskite absorbers, with their high open circuit voltage to band-gap ratio, are particularly suited for this purpose.
Here methylammonium lead bromide and its mixed halide form, both with an optical band-gap of 2.3 eV were used as absorbers in a mesoporous p-i-n device configuration. Through judicious selection of the organic hole conductor with suitable band alignment and band-gap to minimize losses, a solar cell showing Voc above 1.5 V and short circuit currents of ca. 4 mA/cm2 was demonstrated. Analysis of the loss mechanisms and the proposed route for further improvement of the cell performance is discussed.
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.
