Perovskite-based solar cells (PSCs) are the most fascinating solar-to-electricity converting technologies in the new century. The urge of searching for alternative hole-transporting materials (HTMs) for high-performance perovskite-based solar cells is growing. Rencently we have developed new category of porphyrin-based hole-transporting materials which are structurally simple, easy to prepare and well performed. For PSC device based on porphyrin HTM Y2, high performance with PCE of 13.82% with open-circuit voltage (VOC) and short-circuit current (JSC) of 1.01 V and 20.88 mA cm-2, respectively, is observed comparable to that based on Spiro-OMeTAD where PCE = 14.67% (VOC = 1.04 V and JSC = 20.87 mA cm-2). However, the long chain tethered Y2A2 shows lower PCE of 10.55% (VOC = 1.01 V; JSC = 17.80 mA cm-2). It is found that Y2 and Spiro-OMeTAD are of similar HOMO level and of the same order of hole mobility at 10-4 cm2 V-1 s-1. Our results offer new class of high performance hole-transporting materials for perovskite-based solar cells. To our knowledge, it is the highest-performance solar cell device (including dye-sensitized solar cells and organic photovoltaics) ever reported that is incorporated with porphyrin materials.
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.
