Monoclinic-scheelite BiVO4 has been widely studied as a promising oxygen evolution reaction (OER) catalyst in artificial photosynthesis. Though significant progress to improve or augment its catalysis performance has been made, fundamental understanding of its relatively poor performance as a bare material is lacking. In this paper, we report the correlation of the surface structure and trap st...

A cyclometalated Ru dye bearing two triphenylamine groups to augment light absorption exhibits a power conversion efficiency (PCE) in excess of 7% in the dye-sensitized solar cell despite having a large molecular footprint on TiO(2).

Introduction Conclusions References

Y(3)Al(5)O(12):Ce phosphors have been prepared and used as an effective scattering layer on top of a transparent layer of nanocrystalline TiO(2) for dye sensitized solar cells (DSSCs). The Y(3)Al(5)O(12):Ce scattering layer increases the photocurrent of DSSCs due to the enhanced light harvesting mainly via the improved light absorption and scattering. Under one sun illumination (AM 1.5G, 100 mW...

a total number of 67 workers of teheran battery workshops were investigated for probable lead absorption due to the working with lead storage batteries. twenty workers with other occupations were selected as control group. blood and urine analysis were carried out for both groups. lead content of the urine in about 95.5% of the subjects was below 10 μg/100 ml. two subjects showed higher concent...
