Abstract
A method for forming a perovskite solar cell includes: depositing a mixture comprising a sulfonium-based passivation material, a fullerene derivative, and a hole-blocking material on a surface of a substrate comprising a perovskite layer to form a single-step multifunctional layer; and further processing the substrate and the single-step layer to form a perovskite solar cell.

A method for forming a perovskite solar cell, comprising:
- depositing a mixture comprising a sulfonium-based passivation material, a fullerene derivative, and a hole-blocking material on a surface of a substrate comprising a perovskite layer to form a single-step multifunctional layer;
- and
- further processing the substrate and the single-step layer to form a perovskite solar cell.
A perovskite solar cell, comprising:
- a perovskite absorber layer;
- a single-step interfacial layer deposited on the perovskite absorber, comprising a sulfonium-based passivation material, a fullerene derivative, and a hole-blocking material;
- and
- an electrode deposited on the single-step layer,
- wherein the single-step layer simultaneously provides chemical passivation, electron transport, and hole blocking.
