1. A method for fabricating an organic active material for a solar cell, the method comprising:
providing a metallic substrate which enables self-assembly of organic molecules;
forming an organic molecular block on the metallic substrate, wherein the organic molecular block includes a metal-molecule multilayered heterostructure formed by metal-ion mediated self-assembly of organic molecules;
wherein the metal-molecule multilayered herterostructure includes a plurality of self assembly monolayers connected by metal ions;
wherein the organic molecular block is formed by immerising the metallic substrate in a first solution to create a molecular self-assembly and then immersing in a second solution to provide metal ions on the molecular self-assembly, where the metal ions serve as mediators for formation of a subsequent molecular self-assembly; and
wherein immersing the metallic substrate in the first solution and then in the second solution is repeated to form the organic molecular block.
