Abstract and subjects
Perovskites are low-cost semiconductors enabling a variety of high-performance optoelectronic applications. The rapid progress made in this field is driven by the development of high-efficiency photovoltaic devices. The perovskite solar cells adapt a thin-film device architecture where a uniform, crystalline thin film is required to deliver high-power conversion efficiency. This chapter will introduce the solution-based thin-film deposition methods that are used for lab-scale solar cell fabrication. Next, we will discuss the current status and challenges of scaling solar cells to solar modules. Solution coating method and chemical vapor deposition will be discussed for perovskite mini-module demonstrations. Finally, we will provide future perspectives of thin-film coating methods for solar panel development.
