ABSTRACT:
A photoelectrochemical cell may include a cell housing defining an interior volume with a window affixed to the cell housing for allowing the passage of light into the interior volume of the cell. A polymeric film may be affixed within the interior volume defining an anterior compartment and a posterior compartment within the cell housing. A plurality of semiconductor particles embedded continuously within a through thickness of the polymeric film so that a first respective surface area of the plurality of semiconductor particles is exposed to the anterior portion of the cell and a second respective surface area of the plurality of semiconductor particles is exposed to the posterior portion of the cell. The membrane may be immersed within an electrolyte so that incident radiation on the semiconductor particles causes oxidation and reduction to occur within the cell to produce gaseous hydrogen and oxygen.
