Mini-review on all-inorganic lead-based perovskite solar cells: challenges and opportunities for production and upscaling

Perovskite photovoltaic solar cells have gained popularity throughout the past few years. They have become the subject of multiple research studies due to their ability to achieve high efficiencies, specifically all-inorganic perovskite solar cells. They demonstrate a record operational lifetime and are also cheap to manufacture and highly efficient. This paper intends to build on the existing knowledge and provide a detailed summary of how these perovskites work and the technology behind as well as the various fabrication methods. The review will also consider the production challenges while presenting upscaling alternatives to overcome them.
