One novel blue coulored organic donor-$\pi$-acceptor sensitizer Dyenamo-Blue has been applied for highly efficient solid-state dye-sensitized solar cells (ssDSSCs) in the first time. Using 2,2',7-,7'-tetrakis (N,N-di-p-methoxyphenyl-amine ) 9,9'-spirobifuorene (Spiro-OMeTAD) as the hole transport material (HTM), excellent power conversion efficiency of over 5% was recorded together with an open-circuit voltage of 860 mV under standard AM 1.5G illumination (100 mW cm\textsuperscript{-2}). By cosensitized with D35 dye, the solid state solar cell showed excellent efficiency of over 7%, with high current of 12.41 mA cm\textsuperscript{-2} and open circuit voltage of 880 mV. The results also showed that the Voc of solid state dye sensitized solar cells can be improved via cosensitization strategy due to suppressed recombination losses. In addition, photo-induced absorption (PIA) spectroscopy showed efficient dye regeneration in cosensitized solar cells in corresponding to their high photocurrent. The results of our research will guide the design of aesthetic and highly efficient ssDSSCs for scaling up production in the very near future.
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.
