Abstract
Wire-shaped perovskite devices and methods for manufacturing the same are provided. The perovskite devices have a uniform layer thickness of perovskite material on wire-shaped substrates of semi-conductor or carbon material. The method includes an electro-coating process, which advantageously allows for predictability and repeatability.
Claims20
A device comprising:
- a wire-shaped semi-conductor substrate comprising a carbon nanotube yarn;
- and
- a perovskite coating on an outer surface of the wire-shaped semi-conductor substrate.
A method of making a wire-shaped perovskite device, the method comprising:
- depositing a perovskite solution onto an outer surface of a wire-shaped semi-conductor substrate;
- and then
- annealing the deposited perovskite solution by Joule heating to produce a perovskite coating on the wire-shaped semi-conductor substrate;
- and
- optionally, repeating said depositing and annealing in order to build successive layers of the perovskite coating on the wire-shaped semi-conductor substrate.
2 more elements
A wire-shaped photodetector comprising:
- a flexible wire-shaped semi-conductor substrate comprising carbon nanotube yarn;
- and
- a crystalline perovskite coating annealed onto an outer surface of the wire-shaped semi-conductor surface.
