Abstract Inverted perovskite solar cells (PSCs) have attracted considerable attention due to their distinct advantages, including minimal hysteresis, cost‐effectiveness, and suitability for tandem applications. Nevertheless, the solution processing low formation energy of perovskites inevitably lead numerous defects formed at both bulk interfaces layer. These can act as non‐radiative recombination centers, significantly impeding carrier transport posing a substantial obstacle stability further enhancing power conversion efficiency (PCE). This review delves into detailed discussion nature origin characterization techniques employed defect identification. Furthermore, it systematically summarizes methods detection approaches passivating interface within film in inverted PSCs. Finally, this offers perspective on employing upscaling passivation engineering modules. It is hoped provides insights PSCs

Abstract We report a highly crystalline self‐assembled multilayer (SAMUL) that is fundamentally different from the conventional monolayer or disordered bilayer used for hole‐extraction in inverted perovskite solar cells (PSCs). The SAMUL can be easily formed on ITO substrate to establish better surface coverage enhance performance and stability of PSCs. A detailed structure‐property‐performance relationship molecules established through systematic study their crystallinity, molecular packing, hole‐transporting properties. These SAMULs are rationally optimized by varying structures deposition methods thermal evaporation spin‐coating fabricating CbzNaphPPA‐based was chosen PSCs due it exhibiting highest crystallinity hole mobility which derived ordered H‐aggregation.

Tuning Self‐Assembly of Hole‐Selective Monolayers for Reproducible Perovskite/Silicon Tandem Solar Cells

Small Methods, Год журнала: 2025, Номер unknown

Опубликована: Фев. 25, 2025

Self-assemble monolayers (SAMs) have become state-of-the-art hole-selective contacts for high-efficiency perovskite-based solar cells due to their easy processing, passivation capability, and low parasitic absorption. Nevertheless, the deposition of SAMs with a monolayer thickness high packing density on metal oxide substrates, critical challenges persist. To overcome these, study focuses impact annealing temperature - an intrinsic yet so far unexplored process parameter during formation SAMs. By performing in situ angle-resolved X-ray photoelectron spectroscopy combined advanced data analysis routines, it is revealed that increasing reduces formed SAM layer from multilayer stack ≈5 nm at 100 °C (conventional employed literature) 150 °C. Furthermore, denser adsorption surface promoted temperatures, which enhances interfacial SAM/perovskite quality. With this strategy, 1.3%abs power conversion efficiency (PCE) increment obtained fully-textured perovskite/silicon tandem cells, improved reproducibility, champion device approaching 30% PCE. This advances understanding presents promising strategy further progress cells.

Abstract The inverted perovskite solar cells based on hole‐selective self‐assembled molecules (SAMs) have been setting new efficiency benchmarks. However, the agglomeration of SAM and lack defect passivation ability are two critical issues that need to be addressed. It is demonstrated by blending co‐adsorbent 4‐phosphoricbutyl ammonium iodide (4PBAI) with 4‐(7H‐dibenzo[c,g]carbazole‐7‐yl) phosphonic acid (4PADCB), enhanced homogeneity, conductivity, better energy levels can realized for co‐SAM contact. functional group 4PBAI also effectively passivate defects at buried interface template high‐quality growth. Assisted synergistic top modification, power conversion optimized device reaches 24.96%, which retain 95% initial after 1200 h in ambient unencapsulated device. findings suggest a well‐designed address limitations further enhance performance cutting‐edge SAMs.
