Today, the efficient and economic access to renewable energy sources is one of the fundamental challenges to every industrialized country. Besides the use of wind and water, access to solar energy is of key importance and this is represented by the broad scientific field of photovoltaics. Solar cells based on sensitizers containing the ruthenium have existed since 1993, but they suffer from several drawbacks the most crucial of which is high cost and the use of a non-Earth abundant metal.
Our group focuses its research on n-type dye-sensitized solar cells (DSCs), which combine the use of Earth abundant metal complexes as dyes to address the current limitations of the known photovoltaic systems [1]. Recently, we have focused attention on developing new electrolytes to improve the solar-to-electrical energy conversion efficiency of DSCs with a previously reported N-heterocyclic carbene iron(II) dye [2, 3].
In this work, we have demonstrated that changes in solvent, ionic liquid and additive in the electrolyte could be crucial for the performance of DSCs. The enhanced efficiency was reached by tuning the electrolyte composition with an I–/I3– redox shuttle (up to 0.51% photoconversion efficiency, 8.5% relative to N719 set at 100%, compared to PCE = 0.13% previously published [2]). Moreover, our DSCs demonstrated long-term stability over a period of 40 days.

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.
