Interlayer materials play a vital role in mitigating the energetic mismatch between active materials and metal electrodes in various optoelectronic devices. The well-aligned electronic levels lead to an improvement in fill-factor (FF), open circuit voltage (Voc) and, consequently, power convention efficiency (PCE). Copper(I) thiocyanate (CuSCN) is a widely known candidate for transparent hole transport layer (HTL) in emerging solar cells, owing to its solution-processibility and low parasitic absorption in the visible and infrared range.[1] However, solution-processed films of CuSCN exhibit suboptimal microstructure and suffer from structural defects.[2-4] Doping CuSCN with appropriate dopants has shown promising improvements in microstructural and hole transport properties that result in enhanced device performance.[4,5] In this work, interfacial doping using potassium thiocyanate (KSCN) was employed to compensate for hole-killing thiocyanate vacancies (VSCN) in CuSCN films. An eight-fold improvement in the hole mobility was observed in CuSCN-based thin-film transistors when KSCN was included, suggesting a significant enhancement of hole transport properties. When KSCN/CuSCN was incorporated as the HTL in organic photovoltaics (OPVs), the excellent optical properties were unaffected while promising changes were observed in the modified OPVs: Voc increased from 0.73 up to 0.78 V along with a slight increase in FF. This enhanced device performance could be explained based on the improvement in microstructural and charge extraction ability of the HTL.
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.
