摘要

At present, the power conversion efficiency of perovskite solar cells exceeds 25%. Their rapidly increasing efficiency has made people increasingly optimistic about their commercial application, but the stability of perovskite remains the biggest obstacle to successful commercialization. Quasi-two-dimensional perovskite solves this problem. Utilizing the hydrophobicity and thermal stability of large organic spacer cations, quasi-two-dimensional perovskite can effectively improve the stability of perovskite and improved crystal formation energy while providing a more stable structure. Quasi-two-dimensional perovskite also invites significant improvement to the morphology of perovskite films, which can replace anti-solvent processes, simplify production, and meet the industrial production requirements of perovskite. However, the relatively large band-gap and low carrier mobility caused by insulated organic spacer cations hinder ion transmission, causing quasi-two-dimensional perovskite solar cells to be far less efficient than three-dimensional perovskite solar cells. Therefore, for quasi-two-dimensional perovskite, it is necessary to further study its characteristics and device applications to achieve further optimization of device performance. This article summarizes the research progress of quasi-two-dimensional perovskite solar cells, the molecular structure of quasi-two-dimensional perovskite, the methods and principles of quasi-two-dimensional doping that improves the stability of three-dimensional perovskite, and the phase distribution and carrier transport characteristics of quasi-two-dimensional perovskite. Then this paper analyzes the problems faced by quasi-two-dimensional perovskite solar cells and looks forward to their prospects. It is expected that it will provide a reference for the preparation of efficient and stable quasi-two-dimensional perovskite solar cells.
