Improvement in interlayer structure of p–i–n-type organic solar cells with the use of fullerene-linked tetrabenzoporphyrin as additive

Pristine π-extended aromatic compounds are attractive as organic functional materials including organic semiconductors, but are difficult to synthesize in pure form because of their low solubility in common organic solvents. The precursor approach is a very useful method to synthesize pure π-extended aromatic compounds that cannot be prepared via traditional organic synthesis in flasks. In this approach, pure precursors are first prepared; these precursors are then converted quantitatively to the target molecules via a retro-Diels–Alder reaction or Strating–Zwanenburg photodecarbonylation reaction. This approach has also been used for the on-surface synthesis of the large acenes, heptacene and nonacene, under ultra-high vacuum in order to investigate their electronic properties, and is useful for the control of the packing structure of organic semiconductors in solution–processed films. The charge carrier mobilities of organic photovoltaics and organic field effect transistors have been improved using the precursor approach in combination with substituent effects. This account focuses on the synthesis and morphological control of aromatic compounds using the precursor approach in our group in the last decade.

Improvement in interlayer structure of p–i–n-type organic solar cells with the use of fullerene-linked tetrabenzoporphyrin as additive

Abstract: The power conversion efficiency of p–i–n-type OPV was improved by 50% by addition of 5 wt% of BP–C60 to the interlayer, composed of BP and PC61BM, by increasing the miscibility and interface area of the two components.
