Abstract: A method for forming a single atom catalyst on a two-dimensional support material involves providing the two-dimensional support material. The two-dimensional support material is combined with at least two heteroatoms and a metal to form a solution. Liquid is removed from the solution to form a material that includes the two-dimensional support material, the at least two heteroatoms, and the metal. The material including the two-dimensional support material, the at least two heteroatoms, and the metal is heated to form the single atom catalyst that includes single atoms of the metal. The at least two heteroatoms bind the single atoms of the metal to, and stabilize the single atoms of the metal on, the two-dimensional support material.

Abstract: A solar cell includes a p-type silicon layer having a first side and a second side and an n-type silicon layer having a first side and a second side. The first side of the n-type silicon layer is arranged on the second side of the p-type silicon layer. The solar cell also includes a first metal electrode arranged on the first side of the p-type silicon layer and a second metal electrode arranged on the second side of the n-type silicon layer. The second metal electrode includes an MXene.

Abstract: Embodiments of the present disclosure describe a photoelectrochemical (PEC) cell comprising a semiconductor photoelectrode configured with at least two light-harvesting faces; a catalyst layer deposited on at least one light-harvesting face and in contact with an electrolyte; a reference electrode deposited on at least another light-harvesting face; and a counter electrode in contact with the electrolyte.

Abstract: A photoelectrochemical device includes a substrate having a metallic electrocatalyst, a first ohmic contact layer arranged on the substrate, a tandem photoabsorber arranged on the first ohmic contact layer, a second ohmic contact layer arranged on the tandem photoabsorber, and a protective layer arranged on the second ohmic contact layer. The substrate is comprised of a different material than the tandem photoabsorber.

Abstract: A photoelectrochemical (PEC) cell for splitting water into hydrogen and oxygen is described herein. The PEC cell includes a first side configured to capture electromagnetic energy. The PEC cell further includes a second side opposed to the first side comprising an anode electrode and a cathode electrode. The PEC cell further includes a buried p-n junction that converts electromagnetic energy received at the first side into electrical energy. The electrical energy is used to catalyze oxygen and hydrogen at the second side of the PEC cell.
