Upon the formation of the surface complexes of organic molecules (TCNQ, 2-anthroic acid) with TiO2 nanoparticles, new visible light absorption bands appear due to interfacial charge-transfer (ICT) transitions from these organic molecule's adsorbates to the conduction band of TiO2 directly. Therefore, ICT transitions are expected to be a novel charge-separation mechanism for efficient photovoltaic conversion featuring one-step charge separation with energy loss [1]. In this study, the complexes of each organic molecules TCNQ and 2-anthroic acid with Nb doped TiO2 electrode were fabricated such as dye-sensitized solar cells (DSSCs) and investigated the improvement of charge-transfer process of them. The Nb doped TiO2 nanoparticles were prepared by hydrothermal method at 180 ºC for 24 h [2]. According to dope Nb into TiO2 lattice, its level of the conduction band could be closer to these organic molecule's adsorbates than its of Un doped TiO2 [3]. That is, the injection of ICT transitions could be shortly. This presentation will mainly discuss the surface of the Nb doped TiO2 nanoparticles chemically absorbed with these organic molecules by using incident photon-to-current conversion efficiencies (IPCE) and I-V measurement. Furthermore, the present description will also focus on the effect of carrier recombination due to ICT transitions with the Nb doped TiO2

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.
