A perovskite solar cell (PSC) equipping with an efficient electron transporting layer (ETL) is essential for high efficiency, good reproducibility and low hysteresis control. However, the efficient exciton extraction between ETL and perovskite is a crucial factor for high performance PSCs. Much research about doped TiO2 has been done to improve the efficiency of photovoltaic devices In this study, a Nb-doped TiO2 ETL was anodically electrodeposited in constant current fashion from an aqueous TiCl3 solution containing NbCl5 additive. The morphology of the Nb-doped TiO2 film was examined by scanning electron microscopy (SEM), Kelvin probe force microscope (KPFM), and X-ray photoelectron spectroscopy (XPS), whereas the optical and electrical properties of Nb-doped TiO2 ETL were measured by UV-Visible (UV-Vis) spectroscopy, photoluminescence (PL) spectroscopy and Mott-schottky (MS) plot. Currently, the results confirm that the Nb-doping not only improved the conductivity of TiO2 ETLs but also affected the surface morphology of film considerably, demonstrating a facile way to adjust TiO2 ETL’s property via additive strategy in electrodeposition solution.
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.
