Exploration and development of ‘green’ materials for photovoltaic devices have attracted intense attention since green plants exemplify solar energy conversion. Inspired by the sophisticated system of nature plants, here, we have demonstrated an eco-friendly and effective light sensitizer to be applied in solar cells, which can be prepared in one step via hydrothermal treatment of celery leaves extractive. Heat treatment will degrade the natural dyes and introduce carbon quantum dots (CQDs) into the extractive. The effects of hydrothermal temperatures on the CQD formation and the nature dye survival have been investigated. Experimental results indicate after heat-treatment at 120°C for 2.5 hours, the formed CQDs have particles size ranged from 4~6 nm together with some dyes surviving. The nanocrystalline TiO2 solar cells using this hydrothermally treated extractive as light sensitizer can achieve the best power conversion efficiency of 0.482% under AM 1.5G one full sun illumination, which is 1.7 times higher than the solar cell using the original extractive as the sensitizer and 1.5 times higher than the one based on pure CQD sensitizer. The doped CQDs can improve the energy efficiency by facilitating the electron/energy transfer in the dye-semiconductor complex and thus may provide a useful approach for the development of highly efficient photoelectric devices.
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.
