We report on the effect of Na incorporation into Cu(In,Ga)Se2 (CIGS) for thin-film solar cells. Na ions were supplied by NaF films with different thicknesses, while those from the soda-lime glass substrate were controlled by a presence or an absence of a SiOx barrier. Gradually increasing a Na content in CIGS was found in the structures of CIGS/Mo/SiOx/SLG, CIGS/Mo/SLG, CIGS/5 nm-NaF/Mo/SiOx/SLG,...
H.264/AVC outperforms previous video coding with many other tools, but the complexity increases much. As the image resolution is high, the bus bandwidth and data read cycle are the most important problems for the real time processing decoder. Motion compensation is the main bottleneck, which can use about over 50% bandwidth of the total bandwidth. In this paper, we present a bandwidth aware motion...
