We describe a simple, inexpensive coating method to produce thin silica and titania films with surfactant templated, orthogonally tilted cylindrical nanopore arrays. These films can be deposited onto any substrate because orientation of the 2D hexago

Photovoltaic (PV) systems are currently too expensive to compete with grid power. After discussing the cost breakdown of currently available PV technology, we analyze the retail prices of PV necessary to become competitive with grid-power in various

The authors describe the studies of exciton diffusion and charge transport in polymer-titania and polymer-alumina systems. We show that the exciton diffusion length is 12 nm in MDMO-PPV, the effective exciton diffusion length can be even larger if tw
