  • All-back-contact photovoltaic devices using cracked film lithography
    Patent number: 11950436
    Abstract: The present disclosure relates to a device that includes an irregular network of interconnected ridges in physical contact with a planar substrate and a perovskite layer, where the planar substrate include a support layer and a first charge selective contact layer, the first charge selective contact layer is positioned between the support layer and the interconnected ridges, each ridge includes a second charge selective contact layer and an insulating layer, the insulating layer is positioned between the first charge selective contact layer and the second charge selective contact layer, and the perovskite layer substantially covers the plurality of interconnected ridges and the underlying planar substrate.

  • Energy-harvesting chromogenic devices
    Patent number: 10253559
    Abstract: An aspect of the present disclosure is a device that includes a switchable material and an intercalating species, such that when a first condition is met, at least a portion of the intercalating species is associated with the switchable material and the switchable material is substantially transparent and substantially colorless, and when a second condition is met, at least a fraction of the portion of the intercalating species is transferred from the switchable material and the switchable material is substantially transparent and substantially colored.

  • Group IV nanocrystals with ion-exchangeable surface ligands and methods of making the same
    Patent number: 9862841
    Abstract: Methods are described that include reacting a starting nanocrystal that includes a starting nanocrystal core and a covalently bound surface species to create an ion-exchangeable (IE) nanocrystal that includes a surface charge and a first ion-exchangeable (IE) surface ligand ionically bound to the surface charge, where the starting nanocrystal core includes a group IV element.
