“…Furthermore, Jen el al. introduced an ETL‐based coronene (CDIN) with amino‐containing side chains, which can passivate the surface of perovskite surface . Moreover, Li and co‐workers developed two different ETLs di(3‐(pyridin‐4‐yl)propyl) [60]fullerenyl malonate (PCP) with pyridyl terminal group and di(1‐methoxyethyl)[60]fullerenyl malonate) (MCM) with methoxyl terminal substituent) to investigate the passivation strength of different terminal groups and their influence on the hysteresis of the device.…”

Organic n‐type materials (e.g., fullerene derivatives, naphthalene diimides (NDIs), perylene diimides (PDIs), azaacene‐based molecules, and n‐type conjugated polymers) are demonstrated as promising electron transport layers (ETLs) in inverted perovskite solar cells (p–i–n PSCs), because these materials have several advantages such as easy synthesis and purification, tunable frontier molecular orbitals, decent electron mobility, low cost, good solubility in different organic solvents, and reasonable chemical/thermal stability. Considering these positive factors, approaches toward achieving effective p–i–n PSCs with these organic materials as ETLs are highlighted in this Review. Moreover, organic structures, electron transport properties, working function of electrodes caused by ETLs, and key relevant parameters (PCE and stability) of p–i–n PSCs are presented. Hopefully, this Review will provide fundamental guidance for future development of new organic n‐type materials as ETLs for more efficient p–i–n PSCs.

Flexible Perowskit‐Solarzellen werden aufgrund ihres vielversprechenden Potentials in der tragbaren Elektronik intensiv erforscht. Verschiedene Niedertemperatur‐Herstellungsmethoden für Perowskitfilme und große Fortschritte bei der gezielten Abstimmung der Schnittstellen und Elektrodenmaterialien haben zu Effizienzen von über 18 % geführt. Dieser Aufsatz diskutiert die jüngsten Entwicklungen bei flexiblen Perowskit‐Solarzellen mit Schwerpunkt auf: 1) Niedertemperatur‐Herstellungsmethoden zur Verbesserung der Eigenschaften von Perowskitfilmen, wie vollständige Bedeckung, einheitliche Morphologie und gute Kristallinität; 2) Schnittstellen/Grenzflächen in flexiblen Perowskit‐Solarzellen, einschließlich Kennzahlen wie Transmissionsgrad, Ladungsträgerbeweglichkeit, Bandlückenabstand; 3) mechanische und Umgebungsstabilität flexibler Perowskit‐Solarzellen; 4) Ausblick auf flexible Perowskit‐Solarzellen in tragbaren Elektronikgeräten und deren Kosten; 5) Perspektiven zur Kommerzialisierung flexibler Perowskit‐Solarzellen.

“…Fullerene and its derivative phenyl‐C 61 ‐butyric‐acid‐methyl ester (PCBM) are widely used as ETMs for inverted PVSCs, benefiting from their suitable energy level alignment, decent electron mobility, and ease of processability . Because the synthesis of fullerene‐based ETMs is longwinded and complicated owing to multistep syntheses and difficult purification, non‐fullerene ETMs, such as rylene‐based organic small molecules, naphthalene diimide (NDI)‐based polymers and small molecules, and coronene diimide and indacenodithiophene small molecules, are also studied for PVSCs. Among these non‐fullerene ETMs, perylene diimide (PDI)‐based ETMs have attracted much attention, owing to their high electron nucleophilic potential and strong electron‐receiving power .…”

Perylene diimide‐based small molecules are widely used as intermediates of liquid crystals, owing to their high planarity and electron mobility. In this study, tetrachloroperylene diimide (TCl‐PDI) was used as a small‐molecule replacement for TiO2 as electron‐transporting material (ETM) for planar perovskite solar cells (PVSCs). Among hole‐transporting materials (HTMs) for PVSCs, poly(3‐hexylthiophene) (P3HT) gives the devices the highest stability and reproducibility. Therefore, PVSCs with the structure of indium tin oxide (ITO)/ETM/perovskite/P3HT/MoO3/Ag were used to evaluate the performances of new ETMs. A reference device with compact TiO2 and P3HT gave a reasonable power conversion efficiency (PCE) of 12.78 %, whereas the PVSC with TCl‐PDI as ETM gave an enhanced PCE of 14.73 %, which is among the highest reported values for PVSCs with undoped P3HT as the HTM. Moreover, TCl‐PDI‐based devices displayed higher stability than those based on compact TiO2, owing to the superior perovskite quality.
