Abstract:
1. A method for making an optoelectronic device, the method comprising: forming a porous film on a substrate by a templation technique, substantially filling the pores in the porous film with a pore-filling material, removing the porous template film while leaving behind the pore-filling material that substantially filled the interconnected pores of the film, thereby forming a nanoscale grid network comprising interconnected structures of the pore-filling material that are distributed in a substantially uniform fashion with neighboring structures separated by a distance of between about 1 nm and about 100 nm, wherein the structures have diameters of between about 1 nm and about 100 nm; and incorporating a network-filling material into the nanoscale grid network, whereby the network-filling material substantially fills the spaces between the structures in the nanoscale grid network, wherein the nanoscale grid network and the network-filling material have complementary charge-transfer properties with respect to each other to provide a charge-splitting network in the optoelectronic device.
