Titanium dioxide (TiO2) as buffer layer in organic solar cell device
… function metal to oxygen and moisture in air. An inverted structure of organic solar cell (OSC) device with active layers (donor and acceptor) sandwiched by indium tin oxide (ITO) as the cathode and much higher work function metal and more air stable such as aurum (Au) or silver (Ag) as back …

Structural Characterization and Phase Behavior in Supported Metallic Nanoparticles
… by using in-situ extended X-ray absorption fine structure spectroscopy, temperature programmed desorption, and scanning-transmission electron microscopy. The data reveal that during activation in hydrogen the stabilizing CO shell is lost, and the metal centers assume an increasingly metallic …

Polymer and metallodielectric based photonic crystals
… approach in fabricating complex 3-dimensional structures. This thesis focuses on the bottom-up approach in the fabrication of polymeric colloidal photonic crystals and their subsequent modification. Poly(methyl methacrylate) sub-micron spheres were used to produce opals, inverse opals and 3D …

Enhanced Charge Transport and Cell Performance of an Inverted Organic Solar Cell Via UV-ozone Treatment of ZnO
… is its instability in ambient conditions. An inverted structure polymer solar cell was developed to improve the lifetime of the solar cell using an air stable top electrode. The highest efficiency was achieved by treating electron transport layer consisting of ZnO-PVP with UV-ozone. The effect …
