Nanostructured inorganic materials such as TiO2 and ZnO have been widely studied for the application to hybrid solar cells. For the high efficiency in photovoltaic devices, it is important to control p-n interfaces in the nanometer scale. In this study, we employed block copolymer nanotemplates for the fabrication of nanostructured electrodes with atomic layer deposition. In thin films of PS-PMMA diblock copolymers, the morphology and size of the nanostructure of copolymers were controlled by changing the molecular weight and composition of each block. After selective removal of the PMMA block, ordered nanoelectrodes of inorganic materials were fabricated by atomic layer deposition, which can be applied to inverted hybrid solar cells with ordered bulk heterojunction structures. |
