Porphyrins and phthalocyanines in solar photovoltaic cells

Abstract

This review summarizes recent advances in the use of porphyrins, phthalocyanines, and related compounds as components of solar cells, including organic molecular solar cells, polymer cells, anddye-sensitized solar cells. The recent report of a porphyrin dye that achieves 11% power conversion efficiency in a dye-sensitized solar cell indicates that these classes of compounds can be as efficient as the more commonly used ruthenium bipyridyl derivatives.

Investigation of ground and excited state photophysical properties of gadolinium phthalocyanine

“…Due to its structural flexibility, the synthesis and structure-property relationship of phthalocyanines continue attracting attention from the scientific community. For example, phthalocyanines with distinct ligands and central atoms have been used in various applications, such as the photovoltaic material in solar cells [8,9], all-optical switching [10], optical power limiting [11e13], molecular electronics [14,15], 3D optical data storage [16], sensors [17,18], electrochromic and photochromic systems [19,20] and photodynamic therapy [21e23], and so on.…”

Photophysical studies of CdTe quantum dots in the presence of a zinc cationic porphyrin

“…[27][28][29][30] The light-harvesting properties of porphyrins 45 has led them to be considered as components in solar photovoltaic cells. [31][32][33][34] Currently, bulk hetero junctions (BHJ) are Scheme 1 Schematic representation of ZnTMPyP4 and CdTe systems 50 considered to show most promise for improved solar cell efficiency. Recently, BHJs prepared from solution phase PbSe QDs and tetrabenzoporphyrin components were shown to be 40 times more efficient than a flat bilayer heterojunction (FHJ) comprising the same material.…”

Synthesis and characterization of Biphasic Vanadyl phthalocyanine and C₆₀ composite nanoparticles through a reprecipitation process

“…[2] Porphyrins and phthalocyanines (Pc's) have played an important role in the understanding and the development of these types of photovoltaic devices. [3] Tang first reported in 1986 of a heterojunction composed of bilayer organic solar cell composed of CuPc and a perylene derivative. [4] We have previously studied the photoelectrochemistry of organic n/p bilayer of a perylene derivative (3,4,9,10-perylenetetracarboxyl-bisbenimidazole, PTCBI) or fullerene (C 60 ) and metal-free Pc's (H 2 Pc) in water phase, [5][6][7][8][9][10][11][12][13] wherein the evolution of O 2 from water was found to occur along with hole conduction through the p-type layer under visible light irradiation.…”
