Abstract
The coexistence of macroscopic p- and n-type domains in nominally smooth, single-crystal tungsten diselenide photoelectrodes leads to substantial efficiency losses in these crystals. The presence of such regions is demonstrated by rotating-disk electrode experiments, Seebeck coefficient measurements, and in situ topographic photogenerated carrier-collection analysis with a scanning laser spot. These results indicate the importance of controlling growth parameters to yield homogeneously doped crystals to achieve maximum solar conversion efficiencies.
