The electrical and structural behavior of uniformly mixed films of boron subphthalocyanine chloride (SubPc) and C60 and their performance in organic photovoltaic cells is explored. Device performance shows a strong dependence on active-layer donor–acceptor composition, and peak efficiency is realized at 80 wt.% C60. The origin of this C60-rich optimum composition is elucidated in terms of morph...
Metal phthalocyanine tetrasulfonic acids, metal phthalocyanine octacarboxylic acids, metal octakis(hexyloxymethyl)phthalocyanines, and metal anthraquinocyanines have been synthesized. Then, zinc bis(1,4-didecylbenzo)-bis(3,4-pyrido)porphyrazines, the cyclotetramerization products of a 1:1 mixture of 3,6-didecylphthalonitrile and 3,4dicyanopyridine, were synthesized. Futher, subphthalocyanine an...
Herein, both from the experimental and theoretical point of view, optical absorption properties a subphthalocyanine (SubPc), an organic macrocycle commonly used as sunlight harvester, coupled to metallic cavities are analyzed. How different electronic transitions characteristic this compound specifically those that give rise excitonic (Q band) charge transfer (CT couple cavity modes is investig...
Interfacial layers are commonly employed in organic photovoltaic (OPV) cells in order to improve device performance. These layers must be transparent, stable, be compatible with the photo-active materials and provide efficient charge extraction with a good energetic match to the relevant organic material. In this report we demonstrate the compatibility of zirconium acetylacetonate (ZrAcac) elec...
We report a small molecule tandem organic photovoltaic (OPV) cell with a high power conversion efficiency (PCE) of 7.27%. This cell contains two subcells with an identical mixed active layer of C70:5 wt%TAPC (1,1-bis-(4-bis(4-methyl-phenyl)-amino-phenyl)-cyclohexane). The performance was dramatically improved by simply inserting a thin boron subphthalocyanine chloride (SubPc) interlayer, which ...
The self-assembly of umbrella-shaped mesogens is explored with subphthalocyanine cores and oligo(thienyl) arms different lengths in the light their application as light-harvesting photoconducting materials. While shortest arm derivatives self-assemble a conventional columnar phase single mesogen repeating unit, more extended generate dimers that pile up into liquid crystalline columns. In contr...
