Highly Conjugated Three-Dimensional Covalent Organic Frameworks Based on Spirobifluorene for Perovskite Solar Cell Enhancement

Abstract: Highly conjugated three-dimensional covalent organic frameworks (3D COFs) were constructed based on spirobifluorene cores linked via imine bonds (SP-3D-COFs) with novel interlacing conjugation systems. The crystalline structures were confirmed by powder X-ray diffraction and detailed structural simulation. A 6-or 7-fold interpenetration was formed depending on the structure of the linking units. The obtained SP-3D-COFs showed permanent porosity and high thermal stability. In application for solar cells, simple… Show more

“…Sandwiching Tp‐Por COF between ITO/MoO x and ZnO/Al electrodes leads to an open‐circuit voltage of 0.312 V and a short‐circuit density of 44.6 μA cm −2 . Doping the 3D spirobifluorene‐based SP‐3D‐COF 2 (Figure e) into a perovskite solar cell was recently shown to improve the average PCE by 18 % compared to the perovskite cell . This improvement is likely related to a better crystallization of the perovskite, as a result of a templating effect of the SP‐3D‐COF, as well as a better interfacial contact.…”

“…Zwischen ITO/MoO x ‐ und ZnO/Al‐Elektroden geschichtetes Tp‐Por‐COF weist eine Leerlaufspannung von 0.312 V und eine Kurzschlussdichte von 44.6 μA cm −2 auf . Kürzlich wurde für das SP‐3D‐COF‐2 auf 3D‐Spirobifluorenbasis (Abbildung e) bei Dotierung in eine Perowskit‐Solarzelle eine Verbesserung der mittleren PCE um 18 % gegenüber jener der reinen Perowskit‐Zelle gefunden . Diese Verbesserung steht vermutlich in Verbindung mit einer besseren Kristallisation des Perowskits als Folge einer Templatwirkung von SP‐3D‐COF und eines besseren Grenzflächenkontakts.…”

“…Over the past few decades, there has been exponential development in the field of functionalized porous covalent organic frameworks (COFs), these COFs materials have been constructed by purely organic building unit via strong covalent bonds, due to their some textural properties and potential in diverse applications such as high specific surface area, high thermal and chemically stable and large micropore volumes with π‐columnar structure, cost‐effective and modular synthetic procedure to provide a large number of different polymeric architectures. They exhibited large potential applications in many research fields, such as gas adsorption, gas storage, photocatalyst, solarcells, chemosensing, gas separation, water purification membranes, chiral catalyst, and especially used for heterogeneous catalyst . In addition to that, porous COF materials are not soluble in any other organic or aqueous medium, highly stable in high‐boiling solvents.…”
