TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Layer: The photovoltaic layer has column-like super molecules formed by (pi)-(pi)-interaction of single-like polycyclic molecular system having longitudinal access oriented predominantly in the substrate plane, or planar super molecules having polycyclic molecules system with planes formed predominantly parallel to the substrate plane due to lateral interaction of binding groups by strong and weak chemical bond chosen from hydrogen bond, dipole-dipole interaction, cation-(pi) interaction, vander waals-interaction and/or (pi)-(pi) interaction. Preferred Processes: The super molecules forms molecular stacks by (pi)-(pi)-interaction of single-type polycyclic molecular system providing different current-conducting paths with electron and hole conductivity. The molecular stacks are electrically isolated using the group having solubility of organic compound. The molecular stacks are formed predominantly perpendicular to the substrate plane. The predominantly planar polycyclic molecular system is partially or completely conjugated. Preferred Arrangement: The column-like super molecules are positioned predominantly parallel to each other.

EXAMPLE - 5,10,15,20-tetrakis(p-aminophenyl)propyrin (in mg) (15), 1,7-(3'5'-di-t-butylphenoxy)perylene-3,4,9,10-tetracarboxydianhydride (334) and imidazole (3) were added to pyridine (10 ml), stirred and heated under dry nitrogen for 3 hours. The reaction mixture was refluxed for 2 days, and diluted with chloroform. The resultant mixture was washed with hydrochloric acid and water, and dried using anhydrous potassium carbonate, and porphyrine-(phenyl-perylene diimide)4-compound (III) was obtained. The photovoltaic device formed using porphyrin-(phenyl-perylene diimide)4-compound had excellent photovoltaic conversion efficiency.
