Deposition Techniques for Perovskite Solar Cells
Perovskite solar cells have displayed power conversion efficiencies that are close to viable for commercialisation (>20%). The quality of the perovskite films in devices is correlated with the power conversion efficiency measured. Two groups of methodologies have emerged: one-step and two-step deposition, both with their own advantages and disadvantages. This chapter discusses the most important techniques for the deposition of inorganic–organic lead halide perovskites in photovoltaic devices.
