In this contribution, the most significant advances made in the search for low cost natural sensitizers based on anthocyanins are reported through meaningful examples and case studies. We extract with different techniques raw anthocyanins from black carrots. By using selected natural dyes, overall conversion efficiencies above 1% under simulated sunlight have been achieved, which is comparable to that of natural photosynthesis. From the black carrots, we obtained a dark-blue extract employing two new methods: one based on acetone and another based on acid water solutions. We studied the effect of the electrolyte composition on the sensitizer performances and the effect of the thickness of TiO2 layers. Black carrots� solar conversion efficiency was deeply improved by a progressive optimization of the photoanode TiO2 multilayer and of the electrolyte compositions overcoming the best performance reported in literature so far. It�s worth to emphasize that, although presently natural vegetable based DSCs are still below the efficiency requirements for practical applications, our results indicate that these pigments are promising candidates to be potentially exploited, in the future, for production of non-toxic, cheap and fully biodegradable tandem dye-sensitized solar cells and as co-sensitizers since their absorption spectra is complementary to that of others dyes
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.
