Scalable Fabrication Methods of Large‐Area (n‐i‐p) Perovskite Solar Panels

Abstract

Organometal halide perovskite photovoltaic (PV) cells have achieved power conversion efficiencies (PCEs) comparable to the leading crystalline silicon (c‐Si) PV technology. However, despite their exceptional performance, these perovskite solar cells (PSCs) face technological challenges such as large‐area fabrication complexities and outdoor stability concerns. These challenges need to be addressed to pave the way for the commercialization of PSCs. The key to commercializing PSCs lies in developing stable, large‐area solar modules that offer both high efficiency and reliability. Overcoming the hurdles of large‐area module design and fabrication is a crucial step, and researchers are exploring innovative solutions to tackle these challenges. This review article primarily focuses on the development of large‐area PSCs, recent advancements in this field, and the obstacles related to scaling up this technology. It delves into the techniques used to fabricate perovskite films, with a special emphasis on large‐area and large‐scale PSC manufacturing methods. Moreover, the review highlights stability concerns that perovskite solar modules (PSMs) face and reports on recent progress in addressing these issues. The article concludes by summarizing potential future research directions aimed at realizing the full commercial potential of this innovative and promising solar cell technology.
