Interface Regulation via an Organometallic Ferrocene-Based Molecule toward Inverted Perovskite Solar Cells
There is a significant challenge of charge recombination at the perovskite/electron transport layer (ETL), coupled with the need of optimized interface charge transfer in inverted perovskite solar cells (PSCs). In this work, an organometallic ferrocene-based molecule, ferrocenyl-bis-thieno[3,2-b]thiophene-2-carboxylate (FcTTPc), with inherent carboxylate and thiophene functionalities surrounding the central ferrocene motif, is meticulously designed and synthesized for the modification of the perovskite/ETL interface. The carboxylate and thiophene groups in the FcTTPc molecule interact strongly with perovskite components, effectively passivating interface defects. Furthermore, the thiophene group of FcTTPc can engage in robust π–π interactions with the ETL, thereby enhancing interface charge transport. Following the interface modification with FcTTPc, an improved alignment of energy levels is achieved, significantly optimizing carrier transport. Due to the interface modification via the FcTTPc molecule, the champion PSC achieves a PCE of 25.39%. The FcTTPc-modified devices maintained over 96% of their initial efficiency under 40% relative humidity conditions for 1500 h.

期刊介绍:
ACS Energy Letters is a monthly journal that publishes papers reporting new scientific advances in energy research. The journal focuses on topics that are of interest to scientists working in the fundamental and applied sciences. Rapid publication is a central criterion for acceptance, and the journal is known for its quick publication times, with an average of 4-6 weeks from submission to web publication in As Soon As Publishable format.
ACS Energy Letters is ranked as the number one journal in the Web of Science Electrochemistry category. It also ranks within the top 10 journals for Physical Chemistry, Energy & Fuels, and Nanoscience & Nanotechnology.
The journal offers several types of articles, including Letters, Energy Express, Perspectives, Reviews, Editorials, Viewpoints and Energy Focus. Additionally, authors have the option to submit videos that summarize or support the information presented in a Perspective or Review article, which can be highlighted on the journal's website. ACS Energy Letters is abstracted and indexed in Chemical Abstracts Service/SciFinder, EBSCO-summon, PubMed, Web of Science, Scopus and Portico.
