Patent ID: 11939525
Assignee: ALLIANCE FOR SUSTAINABLE ENERGY, LLC
Field: Macromolecular chemistry, polymers (Chemistry)
Classification: CPC C  Y | IPC C

Claim 0:
1. A composition comprising:
a first phase comprising at least one of a three-dimensional (3D) perovskite or a zero-dimensional (0D) perovskite; and
a second phase comprising a switching molecule, wherein:
the first phase and the second phase are in physical contact,
the composition is capable of reversibly switching between a substantially opaque state and a substantially transparent state,
when in the opaque state, the first phase comprises a plurality of pores and the 3D perovskite comprising ABX3,
when in the transparent state, the first phase comprises the switching molecule and the 0D perovskite comprising at least one of A6BX8 or A4BX6,
A comprises a first cation,
B comprises a second cation,
X comprises a first anion, and
the composition is capable of switching between the opaque state and transparent state when the composition transitions through acritical temperature, Tc, between 20° C. and 95° C.
