Proceedings of International Conference on Hybrid and Organic Photovoltaics (HOPV19)
Publication date: 6th February 2020
Organic photovoltaics (OPVs) have attracted much attention as energy-converting devices due to their potential in low cost production, light weight, flexibility, and ease of synthesis. Bulk heterojunction (BHJ) is one of the most promising device architectures that is fabricated from spin-coated mixed layer of donor and acceptor molecules. Such efforts on materials and device optimizations led to the enhancement of power conversion efficiencies (PCEs). Herein, we reported the synthesis and characterizations of A-π-D-π-A type small molecule donor for OPVs. The new molecular donors having alkyl thienyl-substituted benzodithiophene (BDT) as donor, bis(thiophe-2-nyl)thienodioxepine (BTD) as π-spacer and different accepting groups with dicyanomethyleneindanone (DCI) and ethylrhodamine (ER), namely BDT-BTD-DCI and BDT-BTD-ER were designed, synthesized, and characterized, respectively. Their optical, electrochemical properties, and mixed thin film morphology were investigated. The photovoltaic performances of both compounds were evaluated by fabricating the BHJ devices with ITO/PEDOT:PSS/BDT-BTD-DCI:PCBM/BCP/Al and ITO/PEDOT:PSS/BDT-BTD-ER:PCBM/BCP/Al. The donors (BDT-BTD-DCI, BDT-BTD-ER) and acceptors (PCBM) molecules mixed in a well-controlled way in photoactive layer which was optimized by varying ratio of donor/acceptor to enhance device performance. The above results demonstrated that both small molecules are promising in high performance organic photovoltaic applications.
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.
