Photovoltaic Efficiency Optimization of Electrodeposited MAPbI3 Perovskite: Impact of Ammonium Valeric Acid Iodide Additive
Electrodeposition is being investigated as an alternative method for developing large-area perovskite active layers for carbon-based solar cells. This study focuses on incorporating the 5-ammonium valeric acid iodide (5-AVAI) additive into the established MAPbI3 perovskite. Previous research has shown that 5-AVAI can enhance the performance and stability of similar solar cells produced via spin-coating, drop-casting, or inkjet printing. However, its impact on solar cells with electrodeposited active layers remains unexplored. This research investigated the synthesis and characterization of mixed 3D–2D perovskites in the (MAPbI3)1–x((AVA)2PbI4)x family processed by electrodeposition. By varying both the conversion times and 5-AVAI concentrations, we analyzed the structural, optical, and photovoltaic properties of these novel perovskites. An intricate interplay between the conversion parameters and the perovskite properties is evident. Notably, photovoltaic devices with a specific quantity of 5-AVAI showed a 65% enhancement in the power conversion efficiency after 150 h of post-treatment at 40 °C under vacuum. These findings open the way to the improved performance of electrodeposited MAPbI3 perovskites.
期刊介绍：
The journal Chemistry of Materials focuses on publishing original research at the intersection of materials science and chemistry. The studies published in the journal involve chemistry as a prominent component and explore topics such as the design, synthesis, characterization, processing, understanding, and application of functional or potentially functional materials. The journal covers various areas of interest, including inorganic and organic solid-state chemistry, nanomaterials, biomaterials, thin films and polymers, and composite/hybrid materials. The journal particularly seeks papers that highlight the creation or development of innovative materials with novel optical, electrical, magnetic, catalytic, or mechanical properties. It is essential that manuscripts on these topics have a primary focus on the chemistry of materials and represent a significant advancement compared to prior research. Before external reviews are sought, submitted manuscripts undergo a review process by a minimum of two editors to ensure their appropriateness for the journal and the presence of sufficient evidence of a significant advance that will be of broad interest to the materials chemistry community.
