NOVELTY - Photocurrent generation device having nano-composite coaxial cable (10), comprises stacks between first (18) and second (20) electrode, each stack having channels to provide charge transport between electrodes; where outer p-channel includes macrocyclic pi -conjugated planar molecules stacked to form nano-composite coaxial cable with axial channel; and inner n-channel including C60 molecules positioned within axial channel of stack, where stacks form ordered heterojunction to provide charge transport of photocurrent in device.    USE - In photocurrent generation devices such as photovoltaic cell e.g. solar cell.    ADVANTAGE - The vertical alignment enables shortest path for charge migration and maximal terminal contact of nano-composite coaxial cable with electrode, thus enhancing charge collection at electrodes. The extended p-conjugation (coupled with the strong intermolecular p-p interaction) enhances visible absorption, leading to increased light harvesting. The macrocyclic molecules are designed to be multi-functional with strong reducing capability to initiate photoinduced electron transfer with C60 molecules for effective intermolecular p-p interactions to produce strong, organized molecular stacking incorporating C60 within axial channel. The expanded p-system can also enhance intramolecular p-delocalization, helping stabilize charge separation with C60, thus leading to enhanced efficiency of photovoltaic cells.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for forming nano-composite coaxial cable for use in solar cell, involving coating first electrode with continuous film formed of stackable macrocyclic pi -conjugated planar molecules forming several stacks, each stack having an outer p-channel and axial channel substantially perpendicular with plane of first electrode, where C60 molecules are positioned within axial channel to form inner n-channel that forms bulk heterojunction with p-channel; coupling second electrode with film opposite first electrode, where second electrode is parallel with first electrode.
