Fabrication strategies for high quality halide perovskite films in solar cells
Abstract
Perovskite solar cell (PVSC) has emerged as a game-changing photovoltaic technique in recent years. Remarkable advances have been realized in its efficiency, stability, and large-scale fabrication techniques. High-quality halide perovskite films are the core component of PVSCs, which require suitable fabrication strategies. This review includes three key sections to provide a comprehensive overview of these strategies. First, we discuss the crystallization reaction-controlled growth of halide perovskite films from the aspects of intermediates and reaction conditions. Second, organic and inorganic additives are introduced to show their influence on film formation, as well as the underlying mechanism. Third, mass transfer-controlled growth of perovskite films is reviewed, including ion transfer and molecule transfer. Finally, the review is concluded by summing up the key points covered and discussions have been made about the potential routes for the further development of high-quality film fabrication strategies.
