Electrolyte materials are the key components in dye-sensitized solar cells (DSCs) and are very crucial to the performance and long-term stability of DSCs. We developed a series of diamide derivatives as novel low molecular mass organogelators (LMOGs) for D ...

A series of novel near-infrared-absorbing zinc phthalocyanines bearing donor-chromophore-acceptor/anchoring groups have been synthesized to investigate their influence on solar cell performance. With the aim of extending the absorption spectra while mainta ...

This invention pertains to light emitting materials comprising novel ortho-metalated transition metal complexes [C^N] 2 ML comprising two orthometalated ligands having imidazole moieties and an ancillary ligand of ²-diketonate type. It has been surprisingl ...

The present invention provides an improved redox couple for electrochemical and optoelectronic devices. The redox couple is based on a complex of a first row transition metal, said complex containing at least one mono-, bi-, or tridentate ligand comprising ...

A simple diphenylamine-based hole transporting material V1553 was synthesized and incorporated into a perovskite solar cell, which showed remarkable power conversion efficiency close to 23%. The investigated HTM was synthesized via one-step catalyst-free c ...

A new carboxy-Zn(II) phthalocyanine bearing rigid 2,6-diarylphenyl peripheral substituents linked to the macrocycle through alkynyl spacers has been prepared by a convergent approach, which implies a triple Sonogashira coupling between the formyltriiodoZnP ...

We report the first comprehensive comparative synthetic, structural, electrochemical, and spectroscopic study of an extended series of fluorocarbon-modified iridium(III) complexes. We prepared seven new cationic Ir(III) complexes with tert-butyl isocyanide ...

Organic-inorganic lead halide perovskites have shown impressive power conversion efficiency (PCE) in a range of solar cell architectures. Despite the multiple ionic compositions that have been reported so far, the presence of organic constituents is an ess ...

1,6-Dithiophenol-substituted perylene organic sensitizer 1 was synthesized, and its photovoltaic properties in dye-sensitized solar cells were assessed. When anchored onto TiO2 film, the dye exhibits an unprecedented incident monochromatic photon-to-curren ...

We report on five cationic iridium(III) complexes with cyclometalating 2-(3'-trifluoromethylphenyl)pyridine and a diimine, (C boolean AND N)(2)Ir(N boolean AND N), N boolean AND N = 4,4'-R-2-2,2'-dipyridyl or 4,7-R-2-1,10-phenanthroline (R = H, Me, ...

Versatility of Bodipy (4,4-difluoro-4-bora-3a, 4a-diaza-s-indacene) dyes was further expanded in recent dye-sensitized solar cell applications. Here we report a series of derivatives designed to address earlier problems in Bodipy sensitized solar cells. In ...

In pursuit of efficient quantum dot (OD)-sensitized solar cells based on mesoporous TiO2 photoanodes, a new procedure for preparing selenide (Se2-) was developed and used for depositing CdSe QDs in situ over TiO2 mesopores by the successive ionic layer ads ...

The search for new classes of hole transporting materials (HTMs) is a very important task on the way towards commercialization of perovskite solar cells (PSCs). In this work, the synthesis and performance in PSCs of new enamine-based HTMs are presented. Th ...

We report a transient absorption study of the kinetics of re-reduction of ruthenium bipyridyl dye cations adsorbed to nanocrystalline TiO2 films by iodide ions, employing a series of RuII(dcbpy)2X dyes, where dcpby ) 4,4′-dicarboxy-2,2′-bipyridyl and X ) ( ...

Substituted carboxyphthalocyanines (I), wherein both the tert-butyl and carboxyl groups located in the four isoindole rings are located independently in any of the four positions of the corresponding benzene ring of each isoindole ring, its regioisomers an ...

Cationic bis-cyclometalated iridium(III) complexes (C boolean AND N)(2)Ir(N boolean AND N) with 2-(2'-pyridyl)-5-R-1,3,4-oxadiazoles (N boolean AND N; R = 1-adamantyl, mesityl, N-diphenylamino) have a redox gap of 2.58-2.68 V and exhibit orange-red ...
