So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Shehata, M. M.; Makhlouf, M. M.; Kamal, H.; Abdelhady, K. researched the compound: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II)( cas:28903-71-1 ).Reference of 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II).They published the article 《Constructive impact of temperature and frequency on electrical transport performance of cobalt tetramethoxyphenylporphyrin/p-Si hybrid heterojunction solar cell》 about this compound( cas:28903-71-1 ) in Journal of Alloys and Compounds. Keywords: cobalt tetramethoxyphenylporphyrin silicon hybrid heterojunction solar cell elec transport; solar cell temperature frequency constructive impact elec transport. We’ll tell you more about this compound (cas:28903-71-1).
Thin films of cobalt tetramethoxyphenylporphyrin, CoTMPP, have been prepared via thermal evaporation method. X-ray anal. exhibits the polycrystalline and amorphous structural formation for the powder form and the film of CoTMPP, resp. Micrographs of SEM reveal that the CoTMPP film is consisting of nanoparticles like spheres structure (15-28 nm) embedded in amorphous matrix. UV-Vis absorption spectroscopy of as-deposited film has been recorded and from which the Sort and Q bands are observed in a wide range of UV-Vis spectrum. Two others weak bands labeled M and N are detected in UV spectral region. In addition, the film of CoTMPP is grown on the single crystal of p-silicon (p-Si) substrate to fabricate Au/CoTMPP/p-Si/Al hybrid heterojunction solar cell. Complex impedance spectroscopy of the fabricated device is investigated from which, Nyquest spectrum is analyzed at different temperatures ranged from 300 to 380 K. The frequency dependent of the imaginary impedance and the elec. modulus exhibit relaxation phenomena that attributed to the CoTMPP/p-Si and p-Si/Al interfaces, resp. Many elec. parameters including activation energies, depletion width, life times, diffusion coefficients and mobility of the charge carriers were determined and interpreted at these interfaces.
In addition to the literature in the link below, there is a lot of literature about this compound(5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II))Reference of 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II), illustrating the importance and wide applicability of this compound(28903-71-1).
