The dye sensitized solar cell (DSSC) concept is thought as an important alternative to the traditional semiconductor based solar cells because of the limits and problems of these widely used constructs.¹ An important part of these emerging field is the choice of sensitizer.² Bodipy dyes which we use in our studies have a strong reputation as a fluorophoreand in recent years a number of DSSCs have been studied in this concept with these compounds. The first rationally designed example of a Bodipy based sensitizer was reported a few years ago.³ Three Bodipy dyes with strong absorptivities in the visible region were designed and synthesized as potential photosensitizers for liquid electrolyte n-type dye sensitized solar cells. Here, we have synthesized Bodipy derivatives with bis-dimethylfluorenyl amino donor groups for the first time due to its bulky structure as donor groups. We altered our mostly used diphenylaminophenyl group with bis-dimethylfluorenyl group and we have investigated the DSSC efficiencies of a new class of Bodipy dyes. Bodipy dyes were characterized IR, ¹H NMR and ¹³C NMR, elemental and mass analysis. We have investigated the full solar cell characterization of novel Bodipy 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.

MATSUS

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.

International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics

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.
