Proceedings of 13th Conference on Hybrid and Organic Photovoltaics (HOPV21)
Publication date: 11th May 2021
Organic solar cell (OSC) is a very promising photovoltaic technology. Over the past decades, the power conversion efficiencies (PCEs) of OSCs have been promoted from about 1% to currently over 18%. The development of new organic photovoltaic materials, including donor, acceptor and interlayer material, contributed greatly to the rapid increase of PCEs. In the past a few years, we developed many polymer donors based on benzothiophene (BDT) units and applied them to fabricate the PSC devices. For instance, we reported a polymer donor named PBDB-T in 2013 and then modified its chemical structure to obtain a polymer named PBDB-TF in 2015. These two polymers exhibit outstanding photovoltaic properties when blending with fullerene and non-fullerene acceptors. Very recently, the researchers in the field and our team employed PBDB-TF to blend with the newly developed acceptor and realized over 18% efficiencies. In this presentation, some general and efficient molecular design strategies related to this two polymer donors will be summarized and introduced. What is more, some of our recent progress including the OSCs with over 19% efficiencies and new considerations for interpreting the low driving force in the devices will also be briefly introduced.
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.
