Optoelectronic Properties of New Synthesized Phtalocyanine

Abstract

One novel Zn-phthalocyanine bearing different substituent was synthesized. The resulting compounds were characterized by NMR and FTIR. The corresponding polymer was synthesized via cyclic voltametry. The optical properties of these π-conjugated systems were investigated by UV-Visible absorption and photoluminescence (PL) spectroscopy. The electrochemical behavior was reported. The optical and electrochemical gaps were estimated. Those complexes, having low gap energy, have been identified as holding much promise for the developpement of photovoltaic device.

Preparation and optimization of heterojunction donor(DLC) – acceptor(SI) as a solar cell by DFT and PLD

“…Compared to the acceptor, donor materials have greater LUMO and HOMO. But the donor is the material transporting the hole and ideally makes ohmic contact with the anode while electrons are transported by the acceptor materials and the cathode contact [11,12]. The voltage of open-circuit (V oc ) of organic photovoltaic machines is identified by the variance between the energy level of donor HOMO and the acceptor LUMO energy level (V OC = E HOMO D -E LUMO A ) [13,14].…”

Hybrid Bilayer Heterojunction Al/ZnPc/ZnO /ITO Thin Films Solar Cell Prepared by Pulsed Laser Deposition

“…HOMO and LUMO of the donor material should be 0.2-0.3 eV higher than that of the acceptor material, respectively, to achieve effective load segregation. Where is the LUMO of ZnPc and ZnO is -3.6 and -4.3 eV respectively [12][13][14]. If the offset is too tiny, effective charge separation would be difficult; if the offset is too large, a lot of energy loss would occur.…”
