Proceedings of Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP23)
Publication date: 21st November 2022
Perovskite solar cells (PSC) are widening the scope of photovoltaics (PVs) to applications beyond the effective capabilities of conventional silicon-based PVs. They are able to operate efficiently under low light conditions and can easily be printed as cheap lightweight-flexible devices, making them suitable for integration within indoor and portable systems. [1]
The organic hole transporter material (HTM) used plays a major role in controlling the overall performance and cost of PSCs. One challenge is charge recombination, due to charge build- up at the HTM/perovskite interface, which limits the efficiency of the solar cell. [2] In addition, state-of- the-art HTMs, such as Spiro-OMeTAD, are expensive and difficult to synthesise thereby reducing commercially viability. [3] As a result, inexpensive aromatic amide, azomenthine and hydrazone-based HTMs have been developed employing simple Schiff-base condensation chemistry, the structures of which can be tuned to optimise performance. [1,2,4]
By combining theoretical and experimental approaches, we are looking to understand the improved charge transport properties of novel materials with disrupted conjugation in the backbone, built using condensation chemistry. Based on our results, we aim to design and synthesise improved materials for use within PSCs. Here we present our recent findings from theoretical studies on the relationship between the HTM electronic dipole moment and charge carrier mobility.

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.
