Copper phthalocyanine based Schottky diode solar cells

Copper phthalocyanine (CuPc)/Aluminum (Al) Schottky diode solar cells were studied. The thickness of the CuPc layer was varied from 15 nm to 140 nm. Short circuit current densities (Jsc) increased with thickness from 0.042 mA/cm at 15 nm to 0.124 mA/cm at 120 nm reaching saturation at that level. Open circuit voltages (Voc) increased from 220 mV at 15 nm to 907 mV at 140 nm. Analysis of the cur...

Nonequilibrium spin crossover in copper phthalocyanine

We demonstrate the nonequilibrium tip induced control of the spin state of copper phthalocyanine on an insulator coated substrate. We find that, under the condition of energetic proximity of many-body neutral excited states to the anionic ground state, the system can undergo a population inversion towards these excited states. The resulting state of the system is accompanied by a change in the ...

Properties of copper (fluoro-)phthalocyanine layers deposited on epitaxial graphene.

We investigate the atomic structure and electronic properties of monolayers of copper phthalocyanines (CuPc) deposited on epitaxial graphene substrate. We focus in particular on hexadecafluorophthalocyanine (F(16)CuPc), using both theoretical and experimental (scanning tunneling microscopy - STM) studies. For the individual CuPc and F(16)CuPc molecules, we calculated the electronic and optical ...

Theoretical Investigation of the C60/Copper Phthalocyanine Organic Photovoltaic Heterojunction

Molecular heterojunctions, such as the one based on copper phthalocyanine (CuPc) and carbon fullerene (C60) molecules, are commonly employed in organic photovoltaic cells as electron donor–acceptor pairs. We have investigated the different atomic structures and electronic and optical properties of the C60/CuPc heterojunction through first-principles calculations based on density functional theo...
