Title
Hybrid solar cells with ordered TiO2 nanostructures and MEH-PPV
Abstract

For use in hybrid solar cells consisting of TiO2 and poly[2-methoxy, 5-(2′-ethyl-hexyloxy)-1,4-phenylenevinylene] (MEH-PPV), a TiO2 nanostructure which has periodic hexagonal hole arrays was fabricated using surface relief gratings on azobenzene-functionalized polymer films as a template in the sol–gel reaction of a Ti-precusor. The ordered bulk heterojunction solar cells, prepared with the TiO2 nanostructure and MEH-PPV, have a higher power conversion efficiency of 0.21% compared to bilayer and random bulk heterojunction solar cells fabricated with thin-dense TiO2 films and randomly networked TiO2 nanoparticles, respectively, under one sun with air mass 1.5 global illumination.
