Shining a light on solar water splitting.
www.sciencemag.org SCIENCE VOL 344 2 MAY 2014 COVER A blood star (Henricia leviuscula) near Whidbey Island, Washington state. It is one of 10 species of sea star that appear to be affected by a mysterious wasting syndrome on the west and east coasts of North America. Various levels of mortality have been confi rmed in 10 other species, making this the largest documented die-off of echinoderms. ...
متن کاملSolar water splitting cells.
Energy harvested directly from sunlight offers a desirable approach toward fulfilling, with minimal environmental impact, the need for clean energy. Solar energy is a decentralized and inexhaustible natural resource, with the magnitude of the available solar power striking the earth’s surface at any one instant equal to 130 million 500 MW power plants.1 However, several important goals need to ...
متن کاملMetal-encapsulated organolead halide perovskite photocathode for solar-driven hydrogen evolution in water
Lead-halide perovskites have triggered the latest breakthrough in photovoltaic technology. Despite the great promise shown by these materials, their instability towards water even in the presence of low amounts of moisture makes them, a priori, unsuitable for their direct use as light harvesters in aqueous solution for the production of hydrogen through water splitting. Here, we present a simpl...
متن کاملIntegrating a Semitransparent, Fullerene-Free Organic Solar Cell in Tandem with a BiVO4 Photoanode for Unassisted Solar Water Splitting.
We report an unassisted solar water splitting system powered by a diketopyrrolopyrrole (DPP)-containing semitransparent organic solar cell. Two major merits of this fullerene-free solar cell enable its integration with a BiVO4 photoanode. First is the high open circuit voltage and high fill factor displayed by this single junction solar cell, which yields sufficient power to effect water splitt...
متن کاملEfficient solar water-splitting using a nanocrystalline CoO photocatalyst.
The generation of hydrogen from water using sunlight could potentially form the basis of a clean and renewable source of energy. Various water-splitting methods have been investigated previously, but the use of photocatalysts to split water into stoichiometric amounts of H2 and O2 (overall water splitting) without the use of external bias or sacrificial reagents is of particular interest becaus...
