The influence of realistic interface morphologies on light trapping in amorphous silicon thin-film solar cells with periodic surface textures is studied. Realistic interface morphologies are obtained by a 3D surface coverage algorithm using the substrate morphology and layer thicknesses as input parameters. Finite difference time domain optical simulations(More)
ITO/TiO<sub>2</sub>/MEH-PPV/Au solar cells were fabricated using nano-porous titanium dioxide (TiO<sub>2</sub>) infiltrated with poly(2-methoxy-5-(2'-ethylhexyloxy)-p-phenylene vinylene) (MEH-PPV). The TiO<sub>2</sub> films were prepared using poly(ethylene glycol) (PEG) having different molecular weights and spin coated onto indium tin oxide (ITO) coated(More)
Light trapping and photon management of silicon thin film solar cells can be improved by a separate optimization of the front and back contact textures. A separate optimization of the front and back contact textures is investigated by optical simulations taking realistic device geometries into consideration. The optical simulations are confirmed by(More)
