Abstract: The present invention is directed to photovoltaic and photogalvanic devices and methods of generating electrical energy and power or detecting light therefrom, based on a novel nano-enhanced bulk photovoltaic effect using non-centrosymmetric crystals, including ferroelectric and piezoelectric materials, where the non-centrosymmetry is the equilibrium state or it is static or dynamically induced. In certain embodiments, the device comprises a layer of non-centrosymmetric crystalline materials, and a plurality of electrodes disposed in an array upon or penetrating into at least one surface of the crystalline material, the electrodes being optimally spaced to capture the ballistic carriers generated upon irradiation of the crystalline material.

Abstract: The present disclosure is directed to using MXene compositions as templates for the deposition of oriented perovskite films, and compositions derived from such methods. Certain specific embodiments include methods preparing an oriented perovskite, perovskite-type, or perovskite-like film, the methods comprising: (a) depositing at least one perovskite, perovskite-type, or perovskite-like composition or precursor composition using chemical vapor deposition (CVD), physical vapor deposition (PVD), or atomic layer deposition (ALD) onto a film or layer of a MXene composition supported on a substrate to form a layered composition or precursor composition; and either (b) (1) heat treating or annealing the layered precursor composition to form a layered perovskite-type structure comprising at least one oriented perovskite, perovskite-type, or perovskite-like composition; or (2) annealing the layered composition; or (3) both (1) and (2).

Abstract: A method of growing a FE material thin film using physical vapor deposition by pulsed laser deposition or RF sputtering is disclosed. The method involves creating a target to be used for the pulsed laser deposition in order to create a KBNNO thin film. The resultant KBNNO thin film is able to be used in photovoltaic cells.
