ARTHUR B. ELLIS and BRADLEY R. KARAS Department of Chemistry, University of Wisconsin—Madison, Madison, WI 53706 The need for alternate energy sources has led to the rapid development of photoelectrochemical cells (PECs). A PEC consisting of an η-type semiconductor, a counterelectrode, and a suitably chosen electrolyte can convert optical energy directly into chemical fuels and/or electricity Q»2.»3,4). We recently reported that tellurium-doped CdS (CdS:Te) mimics undoped CdS in its ability to sustain the conversion of monochromatic ultraband gap light (>2.4 eV; λ
