Abstract Perovskite solar cells (PSCs) have reached a certified 25.2% efficiency in 2019 due to their high absorption coefficient, carrier mobility, long diffusion length, and tunable direct bandgap. However, the nature of solution processing rapid crystal growth perovskite thin films, variety defects can form as result precursor compositions conditions. The use additives affect crystallization film formation, defect passivation bulk and/or at surface, well influence interface tuning structure energetics. Here, recent progress additive engineering during formation is discussed according following common categories: Lewis acid (e.g., metal cations, fullerene derivatives), base based on donor type O‐donor, S‐donor, N‐donor), ammonium salts, low‐dimensional perovskites, ionic liquid. Various additive‐assisted strategies for optimization are then summarized; include modifiers improve electron‐ hole‐transport layers those modify surface properties. Finally, an outlook provided research trends with respect PSC development.

In several photovoltaic (PV) technologies, the presence of electronic defects within semiconductor band gap limit efficiency, reproducibility, as well lifetime. Metal halide perovskites (MHPs) have drawn great attention because their excellent properties that can be achieved even without a very strict film-growth control processing. Much has been done theoretically in describing different point MHPs. Herein, we discuss experimental challenges thoroughly characterizing MHPs such as, assignment type defects, densities, and energy positions induced by these defects. The second topic this Review is passivation strategies. Based on literature survey, types are important to consider need minimized examined. A complete fundamental understanding defect nature needed further improve optoelectronic functionalities.

Abstract The performance of perovskite solar cells is sensitive to detrimental defects, which are prone accumulate at the interfaces and grain boundaries bulk films. Defect passivation each region will lead reduced trap density thus less nonradiative recombination loss. However, it challenging passivate defects both bottom charge transport layer/perovskite interface, mainly due solvent incompatibility complexity in formation. Here SnO 2 ‐KCl composite electron layer (ETL) utilized planar simultaneously ETL/perovskite interface film. K Cl ions contact. Meanwhile, from ETL can diffuse through film boundaries.

3D perovskite solar cells (PSCs) have shown great promise for use in next-generation photovoltaic devices. However, some challenges need to be addressed before their commercial production, such as enormous defects formed on the surface, which result severe SRH recombination, and inadequate material interplay between composition, leading thermal-, moisture-, light-induced degradation. 2D perovskites, organic layer functions a protective barrier block erosion of moisture or ions, recently emerged attracted increasing attention because they exhibit significant robustness. Inspired by this, surface passivation employing perovskites deposited top counterparts has triggered new wave research simultaneously achieve higher efficiency stability. Herein, we exploited vast amount literature comprehensively summarize recent progress 2D/3D heterostructure PSCs using passivation. The review begins with an introduction crystal structure, followed advantages combination perovskites. Then, strategies, optoelectronic properties, enhanced stability, performance are systematically discussed. Finally, perspectives techniques offer insight into further improved future proposed.
