Photoelectrochemical (PEC) cells based on layered semiconductors are particularly attractive for solar energy conversion for a number of reasons. The preparation of polycrystalline p-WSe/sub 2/ electrodes which show better than 1% red light efficiencies in photovoltaic (regenerative) PEC cells is described. The PEC behavior of these electrodes was investigated in cells containing a number of redox couples. It is difficult to account for the success of these polycrystalline films as photoelectrodes compared to earlier preparations. The method of surface pretreatment of the substrate appears to be important. 27 refs.
