Large-scale perovskite production: materials, processes, and challenges

In the field of solar energy, it has become a common belief that perovskite solar cells
are advancing at an unprecedented pace. While the historical trajectory may seem
astonishing, we can gain insight by examining the development path of the solar cell
industry, which has progressed from silicon and CIGS (copper indium gallium
selenide) to organic solar cells. Perovskite solar cells represent the culmination of
decades of knowledge and research.
A perovskite solar cell is composed of multiple layers. Each layer is carefully
deposited on a substrate, which imposes certain limitations on the choice of
materials and manufacturing processes for the top layer. To overcome these
limitations, various process technologies such as slot-die coating, blade-coating, and
spray deposition have been developed and refined for large-scale production.
Additionally, a wide range of materials has been extensively studied.
In the presentation, we will delve into the critical considerations for selecting
materials and processes when fabricating perovskite solar cells. Furthermore, we will
highlight the challenges and obstacles associated with these technologies.
