Solar fuel generator including a catalytic mesh

This disclosure provides systems, methods, and apparatus related to a solar fuel generator. In one aspect, a device includes a photovoltaic cell, the photovoltaic cell having a first surface and a second surface, a mesh disposed on the first surface of the photovoltaic cell, and a polymer disposed on the mesh and on the first surface of the photovoltaic cell. The mesh has a catalyst disposed thereon. The polymer covers the first surface of the photovoltaic cell, with at least a portion of the mesh not being covered with the polymer.

Vapor phase photo-electrochemical cell

This disclosure provides systems, methods, and apparatus related to a vapor phase photo-electrochemical cell. In one aspect, a device includes a photovoltaic cell, a cathode disposed on the photovoltaic cell, an ionomer membrane disposed on the cathode, and an anode disposed on the ionomer membrane. The cathode includes a cathode catalyst. The ionomer membrane is in contact with the cathode catalyst. The anode includes an anode catalyst. The anode catalyst is in contact with the ionomer membrane. The anode, the ionomer membrane, and the cathode are transmissive to the solar radiation spectrum.
