Porous titania is a promising materials in environmental and energy sector, the improvement of the sensitivity is of social importance, which can be achieved by making highly structured anatase titania. Titania with anatase form is extensively used as a photocatalyst for remediation of contaminated water, air and as photoanode in solar cell. At the nanometer scale, its efficiency is greatly enhanced by the increased in surface area of the particles and modification of their optical properties due to size quantization. So far, the nanoporous titania has been used to remove toxic metal ions from water but disposable of these hazardous metals after removal is a problem. At the same time, metal doped nanoporous titania also in use as photoanode to control the electron recombination in dye sensitized solar cell. Here in, we prepared ionic liquid templated hierarchically porous titania which is used to remove toxic metal ion, lead (CPb2+ = 0.01M) from water. Porous titania efficiently (~ 97%) remove lead ion from water by simple filtration. The nanoporous titania before and after metal extraction was characterized by using XRD, EDAX, CV, Mott-Schottky etc. The lead ion embedded porous titania was used as a photoanode in dye sensitized solar cell (DSSC). The DSSC device shows enhancement in photocurrent, voltage and thus photo-conversion efficiency. The results will be compared with the device fabricated with undoped and commercially available titania nanoparticles (P25). References: [1] Chen, X.; Mao, S. Chem. Rev. 2007, 2891. [2] Moula et. al.

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.
