Patent ID: 7462774

Claim:
A photovoltaic device, comprising: an insulating inorganic nanostructured template having regular template elements between about 1 nm and about 500 nm in diameter with a structure density of between about 10 12 elements/m 2 and about 10 16 elements/m 2 ; a first charge-transfer material coating the nanostructured template material leaving additional space; and a second charge-transfer material filling the additional space, wherein the first and second charge-transfer materials are volumetrically interdigitated, wherein the first and second charge-transfer materials have complementary charge-transfer properties with respect to each other, wherein a lowest unoccupied molecular orbital (LUMO) or conduction band of the first charge-transfer material differs from a LUMO or conduction band of the second charge-transfer material by more than about 0.2 eV, wherein an absorbance of at least one charge transfer material is greater than about 10 3 /cm at the peak of absorption.
