Organic-inorganic hybrid perovskites have been demonstrated to be efficient light absorber for solar cells which reached over 20% power conversion efficiency (PCE) recently. Among many device architectures that have been developed so far for PSCs, the planar heterojunction (PHJ) configuration with metal oxides as a hole transporting material has many advantages such as simple device fabrication, high stability and small hysteresis. The PCE of NiOx based PSCs have been reached to 18.2% with cell size of 1cm-2, which remained 90 % of the initial PCE under 1000 hours light soaking. However, efficient NiOx layer fabricated at high temperature annealing processes (~500°C) cannot use in flexible and tandem solar. Recently, reported a low temperature (130°C) processed NiOx layer spin coated from NiOx nanoparticles and its PSCs achieved PCE of 16.5% with small cell size of 0.07 cm-2. However, any advanced engineering such as particle size of NiOx, its interfaces, and fabrication processes have not been investigated yet.
To improving the performance of PSCs, a series of advanced engineering have been intensely studied. The interface, materials, and fabrication engineering have particularly drawn widespread and sufficient attention, and many significant breakthroughs are eventually achieved. Thus, we have investigated detail properties of nanoparticles, their interfaces, and optimize fabrication processes to improve the PCE in low-temperature processed NiOx based hole transport layer. We have synthesized four kinds of NiOx nanoparticles with different particle size and investigated the photovoltaic proparties using their NiOx nanoparticles. The power conversion efficiency of over 15% have been obtained using NiOx nanoparticle which have particle diameters of 70 nm.
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.
