Dependence of new environmental nano organic semiconductor nickel-(II)-tetraphenyl-21H,23H-porphyrin films on substrate type for energy storage applications

Abstract

Characterization of organic nickel-(II)-tetraphenyl-21H,23H-porphyrin films as a function of substrate type was performed for energy storage applications and consequently environmental enhancement. Nickel-(II)-tetraphenyl-21H,23H-porphyrin films show an amorphous phase. They have a crystallite size of 8-11 nm. Strain caused a shift of different humps' positions. The measured transmittance has high values within the range of 85-91%, and the absorption coefficient values were included within the high-absorption region. Both optical gap and fundamental gap, refractive index, carrier-concentrationto-effective-mass ratio and lattice dielectric constant were calculated, and they were found to be increased, except refractive index and lattice dielectric constant. The obtained data indicated that nickel-(II)-tetraphenyl-21H,23H-porphyrin films are a candidate for energy storage applications.

Efficacy assessment of metalloporphyrins as functional materials for photodetection applications: role of central tetrapyrrole metal ions

“…Consequently, it can be noted that the grown films are composed of a nanostructured crystallite distributed in an orderly manner for a short range in the presence of the dominance of the amorphous nature. These observations about the randomness of the crystal structure of the thermally grown metalloporphyrins thin films were previously reported in much research [21][22][23][24].…”

Blueshifted dielectric properties and optical conductivity of new nanoscale nickel-(II)-tetraphenyl-21H,23H-porphyrin films as a function of UV illumination for energy storage applications

“…The absorption process occurs through this region, and direct or indirect electronic transitions may be available (Tauc 1976;El-Denglawey 2018;Mott and Davis 1971;Pankove 1971). No significant changes can be observed within the transparent or nonabsorbing region at λ > 750 nm (El-Denglawey et al 2020;Wemple and DiDomenico 1969;Mott and Davis 1971;Pankove 1971).…”

“…1b. No sharp peaks can be identified, and only a hump within 2θ (13.8-37.4°) is observed, which characterizes the amorphous phase (Warren 1953;Williamson and Hall 1953;El-Denglawey et al 2020;El-Nahass et al 2016;El-Denglawey 2018;Soliman et al 2015). The structure of the NiTPP films is developed, and the crystalline structure is pronounced after 4 and 8 h of UV illumination.…”

“…Recently, substances with high dielectric properties and low loss tangent (see Fig. 8a,b) have been shown to be good candidates for dielectric and energy storage applications (Zhang et al 2016;El-Denglawey et al 2020;Vidya and Thomas 2018). The loss tangent shows two maximums around energy values of E opt gi and E g ; the topmost value of tan (δ) is 0.51 and corresponds to 8 h of UV illumination.…”

“…(Hassan and Al-Ta'ii 2020). Therefore, decreasing energy consumption is no longer optional but compulsory, and energy should be saved to satisfy the abovementioned purposes (Alptekin et al 2020;El-Denglawey et al 2020;Zhang et al 2016). Energy conservation, savings and storage (ECSS) as a clean energy method can be used to avoid adverse influences on the environment and to counter energy shortages (Alptekin et al 2020;El-Denglawey et al 2020;Zhang et al 2016).…”
