Sequential Spray Deposition (IMAGE) Optica Caption Researchers have developed a new precision spray-coating method called sequential spray deposition that enables multilayer perovskite absorber for advanced solar cell designs and could be scaled up for mass production. The technique could be used to create perovskite architectures with any number of layers.
