Uses

Used in Organic Electronic Devices:
4-(1',5'-dihydro-1'-methyl-2'H-[5,6]fullereno-C₆₀-1H-[1,9-c]pyrrol-2'-yl)benzoic acid is used as a functionalizing agent for the formation of electron-selective layers in organic electronic devices, such as inverted polymer solar cells and perovskite-polymer hybrid solar cells, due to its high electron affinity and electron-donating properties.
Used in Perovskite Solar Cells (PSCs):
In the photovoltaic industry, 4-(1',5'-dihydro-1'-methyl-2'H-[5,6]fullereno-C₆₀-1H-[1,9-c]pyrrol-2'-yl)benzoic acid is used as an electron-selective layer component to enhance the overall efficiency of perovskite solar cells by reducing hysteresis and improving the device's performance.

Formation of [60]fullerene nanoclusters with controlled size and morphology through the aid of supramolecular rod-coil diblock copolymers

On the starting block: Polystyrene-block-poly(4-vinylpyridine) and a [60]fullerene carboxylic acid combine to form spherical supramolecular aggregates (see picture), the size and morphology of which can be controlled by changing the block composition rati

Interfacial modification to improve inverted polymer solar cells

We report improved device performance of poly(3-hexylthiophene) (P3HT) and [6,6]phenyl C61 butyric acid methyl ester (PCBM)-based inverted bulk-heterojunction (BHJ) solar cells through the modified interface of the TiO2/BHJ with a series of carboxylic acid functionalized self-assembled monolayers (SAMs). The SAMs reduce the series resistance and improve the shunt resistance of the cell leading to increased fill factor and photocurrent density. Different aspects of device improvement can be affected depending on the nature of the SAMs. Modification with a C60-SAM shows the largest enhancement leading to a 35% improvement (η = 3.78%) over unmodified inverted devices (η = 2.80%). This SAM serves multiple functions to affect the photoinduced charge transfer at the interface to reduce the recombination of charges, passivation of inorganic surface trap states, improve the exciton dissociation efficiency at the polymer/TiO2 interface as well as a template to influence the overlayer BHJ distribution of phases, morphology and crystallinity leading to better charge selectivity and improved solar cell performance.

WATER-SOLUBLE PHOTOELECTRIC MATERIAL AND THE MANUFACTURING METHOD

The present invention relates to a water-soluble photoelectric material and a method for manufacturing the same. According to the present invention, electron transfers from porphyrin derivatives to C60 fullerene derivatives can be increased as hydrophilicity of a solvent increases by introducing the porphyrin derivatives and C60 fullerene derivatives to pullalan which is a water-soluble polysaccharide. In addition, by providing the water-soluble photoelectric material, the present invention can be variously used in an organic electronics market with competitiveness, which includes a flexible display, an organic light emitting device, an organic thin film transistor, RFID or an organic solar cell, etc.

Photoinduced charge separation in a ferrocene-aluminum(III) porphyrin-fullerene supramolecular triad

Light-induced electron transfer is investigated in a ferrocene- aluminum(III) porphyrin-fullerene supramolecular triad (FcAlPorCeo) and the constituent dyads (AlPorCeo and FcAlPorPh). The fullerene unit (Ceo) is bound axially to the aluminum(IU) porphyrin
