Facile all-dip-coating deposition of highly efficient (CH₃)₃NPbI_3-x Cl _x perovskite materials from aqueous non-halide lead precursor.

ABSTRACT: Sequential all-dip-coating deposition of (CH₃)₃NPbI_3-x Cl _x perovskite materials was conducted in an aqueous nonhalide lead precursor solution, which was followed by that in a (CH₃)₃NI and (CH₃)₃NCl mixed solution as part of a facile, cost-effective, and environmentally benign manufacturing process for high-efficiency perovskite solar cells. The (CH₃)₃NPbI_3-x Cl _x perovskite layers deposited via the proposed process were constructed with a Cl/I ratio below ∼3%, indicating the partial insertion of Cl into the (CH₃)₃NPbI₃ perovskite lattice. The amount of Cl inserted was readily modulated by var
