Abstract:

Photovoltaics composed of organic-inorganic lead halide perovskite materials have a tremendous potential as solar power collectors. Solution-processing enables the cost reduction for perovskite solar cell production due to its high throughput vacuum-free manufacturing process. However, challenges for commercialization of perovskite solar cells remain and are critically dependent on cost-effective scalable fabrication of large and high-quality crystalline perovskite films. In my presentation, we present the basic principles governing the morphologies of spray-coated perovskite films and fabricate up-scaling perovskite solar celles device. This demonstrates the reliability and uniformity of the perovskite films and the corresponding device parameters. These findings highlight the relevance of high-throughput screening of perovskite compositions and the versatility of a scalable solution process, in which active layers are deposited by spray-coating.
