Abstract
A solar cell design is presented that allows energy conversion in solid-state photovoltaics as well as in photoelectrochemical and photoelectrocatalytic cells. The energy-converting structure uses a Schottky-type, (i.e., metallic) nanoemitter, prepared by an oscillatory (photo)electrochemical process. Silicon shows (photo)current oscillations in fluoride-containing electrolytes that form an oxide with interspersed nanopores. Spatially selective electrodeposition of Schottky-barrier metals into these pores produces the nanoemitter contacts. The electrolyte structure shows pronounced photoactivity in a photoelectrochemical cell. Light-induced hydrogen evolution is obtained for structures made with . The energy-band alignments of the structures are discussed and routes for preparation of efficient solid-state devices are outlined.
