Photoelectrochemical water splitting to generate H2 and O2 using only photon energy (with no added electrical energy) has been demonstrated with dual n-type-semiconductor (or Z-scheme) systems. Here we investigated two different Z-scheme systems; one is comprised of two cells with the same metal-oxide semiconductor (W- and Mo-doped bismuth vanadate), that(More)
Depending on the rotational structure of Fresnel reflector, the rotation angle of the mirror was deduced under the eccentric condition. By analyzing the influence of the sun tracking rotation angle error caused by main factors, the change rule and extent of the influence were revealed. It is concluded that the tracking errors caused by the difference(More)
Quaternary-alloyed ZnxCd1-xSySe1-y arrays were prepared from four precursor aqueous/glycerol (3:1) solutions with a robotic piezoelectric dispenser on fluorine-doped tin oxide (FTO) conductive glass. Hydrazine (N2H4) was used for protecting the selenium source, dimethylselenourea, from oxidation so that fabrication of the arrays could be carried out under(More)
