Appl. No.:

17/703446

Inventors:

- Stanford CA, US
Axel F. PALMSTROM - Santa Barbara CA, US
Michael David MC GEHEE - Palo Alto CA, US
Stacey F. BENT - Stanford CA, US

International Classification:

H01L 31/0224
H01L 27/30
H01L 51/42
H01L 51/44
H01L 31/0392

Abstract:

A perovskite-based solar cell comprising a transparent electrode disposed on a buffer layer that protects the perovskite from damage during the deposition of the electrode is disclosed. The buffer material is deposited using either low-temperature atomic-layer deposition, chemical-vapor deposition, or pulsed chemical-vapor deposition. In some embodiments, the perovskite material is operative as an absorption layer in a multi-cell solar-cell structure. In some embodiments, the perovskite material is operative as an absorption layer in a single-junction solar cell structure.
