Set forth herein are pellets, thin films, and monoliths of lithium-stuffed garnet electrolytes having engineered surfaces. These engineered surfaces have a list of advantageous properties including, but not limited to, low surface area resistance, high Liion conductivity, low tendency for lithium dendrites to form within or thereupon when the electrolytes are used in an electrochemical cell. Other advantages include voltage stability and long cycle life when used in electrochemical cells as a separator or a membrane between the positive and negative electrodes. Also set forth herein are methods of making these electrolytes including, but not limited to, methods of annealing these electrolytes under controlled atmosphere conditions. Set forth herein, additionally, are methods of using these electrolytes in electrochemical cells and devices. The instant disclosure further includes electrochemical cells which incorporate the lithium-stuffed garnet electrolytes set forth herein.

Described herein is a method and system for determining a short-circuit current of a solar device before the solar device is tested in a solar simulator. A solar device includes a substrate layer, a front contact layer, a window/emitter layer, an absorber layer and a back contact. A thickness of the window/emitter layer and an absorption wavelength of the absorber layer are determined. The window/emitter layer thickness and absorber layer absorption wavelength are used with a fitting parameter that corresponds to transmission properties of the substrate and first contact layers in order to determine the solar device's short-circuit current.
