Abstract
Official abstract text for this publication.
A method for processing a perovskite photoactive layer. The method comprises depositing a lead salt precursor onto a substrate to form a lead salt thin film, depositing a second salt precursor onto the lead salt thin film, annealing the substrate to form a perovskite material.
First claim
Opening claim text (preview).
What is claimed is: 1. A photovoltaic device comprising: a perovskite material comprising formamidinium lead iodide (FAPbI 3 ) having a cubic crystal structure. 2. The photovoltaic device of claim 1 wherein: the FAPbI 3 has a cubic primitive crystal structure. 3. The photovoltaic device of claim 1 wherein: the FAPbI 3 has a Pm-3m space group. 4. The photovoltaic device of claim 1 wherein: the FAPbI 3 has an X-ray diffraction pattern having peaks, in terms of 2θ, at 14.06±0.1 and 24.30±0.1 degrees. 5. The photovoltaic device of claim 1 wherein: the FAPbI 3 has an X-ray diffraction pattern having peaks, in terms of 2θ, at 14.06±0.1, 19.84±0.1, 24.30±0.1, 28.15±0.1, 31.55±0.1, 34.63±0.1, 40.30±0.1, 42.78±0.1, 45.48±0.1, 49.77±0.1, 51.79±0.1, 58.13±0.1, 58.70±0.1, 62.02±0.1, 65.75±0.1, 67.43±0.1, and 72.81±0.1 degrees. 6. The photovoltaic device of claim 1 wherein: the FAPbI3 has a lattice parameter, a, equal to about 6.35 Å.
