Recent studies on organic and perovskite optoelectronic devices have primarily relied on solution processing. However, from the perspective of commercialization, the vacuum-deposited process is more feasible because the representative OLED industry is based-on vacuum-deposition process.[1] First, we present the development of wavelength-selective organic small molecules from UV to Red with their application in high-performance optical sensors. For narrowband UV selective organic photodetectors (OPDs), three thiazolothiazole-based small molecules were synthesized as an active layer donor.[2] The extended π-conjugation and highly planar backbone was important to improve the intermolecular ordering and efficient charge transport even in the evaporation with C60 acceptor. The resulting OPDs exhibited high responsivity and detectivity with ultrafast response times and a cutoff frequency. Moreover, the devices were successfully monolithically integrated with CMOS image sensors, enabling multifunctional imaging without resolution loss. For R/G/B wavelength selective OPDs, a series of cyclopentadithiophene-based donor molecules were designed for tuning absorption from blue to red while maintaining low molecular weights and thermal stability suitable for vacuum deposition.[3] When blended with C60, a green-selective donor exhibited outstanding performance with external quantum efficiency (EQE) up to 70% and specific detectivity of 2.5 × 10¹² Jones. These devices demonstrated practical applications in visible-light communication and high-resolution X-ray imaging. Seceond, we report novel bathocuproine (BCP) derivatives for cathode buffer layer in perovskite solar cells (PSCs). Substituting phenyl and p-tolyl groups at the 2,9-positions on BCP improves molecular planarity, protects reactive sites, which significantly enhances charge transport, reduces recombination losses, and markedly improves the structural stability of PSCs.[4]
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.
