Recent Advances in Phthalocyanine‐Based Sensitizers for Dye‐Sensitized Solar Cells

Abstract

It is demonstrated that a cationic iridium(III) dichloride phenanthroline complex is capable of CH activation and H/D exchange. It can cleave benzylic and unactivated secondary CH bonds, but exhibits unique selectivity when compared to similar systems that have been studied in the condensed phase. Gas‐phase rate constants and kinetic isotope effects are reported for a variety of substrates and the analysis is supported by DFT calculations at the M06/QZVP level.

Strategic Synthetic Approaches to Porphyrin-Based Artificial Light-Harvesting Systems for Solar Energy Utilization

“…211,212 These properties make them especially suitable for integration in light energy conversion systems. 213 A combination of porphyrin and phthalocyanine macrocycles offers interesting conjugate structures since these molecules have complementary absorptions in the visible region, and the emission spectra of phthalocyanines do not significantly overlap with those of porphyrins.…”

Asymmetric phthalocyanine derivatives containing 4-carboxyphenyl substituents for dye-sensitized solar cells

“…Among the various synthetic dyes being investigated for application in DSSCs, phthalocyanines (Pcs) have been considered to be promising candidates because of their unique optical and electrical properties [7]. These dyes are well known chromophores for their strong absorption around 300 and 700 nm, as well as for their excellent electrochemical, photochemical and thermal stability [8,9].…”

Highly efficient dye-sensitized solar cells based on metal-free and copper(II) phthalocyanine bearing 2-phenylphenoxy moiety

“…To improve the performance of these devices further, it is imperative to enhance their response in the far-red/near-IR wavelength region. Among various synthetic dyes, Pcs have been considered to be promising candidates because of their intensive absorption in the far-red/ near-IR region, and excellent chemical, light, and thermal stability [29,30]. It is also well known that central metals play a major role in tuning the properties of MPcs; Since the CuPcs use as dyes is now overshadowed by other applications such as organic field-effect transistor sensors [31], gas sensor [32], organic solar cells [33], and electro-catalysts [34] copper (II) ion was preferred as central metal.…”
