在钙钛矿太阳能电池中合成并测试了一系列新的分支空穴传输材料(HTM),这些材料包含两个通过非共轭亚甲基苯单元连接的二苯胺取代的咔唑片段。通过一个简单的两步合成程序即可完成所研究材料的合成,从而以高收率提供目标产品。分离的材料显示出良好的热稳定性,并且大多数研究的化合物以非晶态存在,这是有利的,因为没有直接在膜中结晶的风险。最高的电荷漂移迁移率µ 0 = 4×10 -4 cm 2 V -1 s -1在弱电场下测得的,约为。在相同条件下,比Spiro-OMeTAD高一个数量级。从钙钛矿太阳能电池测试结果可以看出,两个新的HTM(V885和V911)的性能与Spiro-OMeTAD相当。由于易于合成,良好的热,光学和光物理性质,这种类型的分子在商业钙钛矿太阳能电池中的实际应用前景广阔。
Vitrigens. I. Synthesis and Characterization of Low Molecular Weight Organic Glasses
摘要:
New low molecular weight organic materials with a strong tendency towards glass formation and glass temperatures above room temperature were synthesized. These materials consist of twin molecules where two bulky groups, i.e. carbazole (Ca), 3,6-dibromocarbazole (DBrCa), 2,3-benzocarbazole (BC), 1,2-benzo-3,4-dihydrocarbazole (BCDH), phenothiazine (Ph), 1,8-naphthalic acid anhydride (NI), and pyrene-l-aldehyde (PY) have been linked by flexible or semiflexible aliphatic or aromatic central units. Their structure-glass temperature relationship and some relations between thermodynamic parameters and amorphous properties are discussed.
series of new branched holetransportingmaterials (HTMs) containing two diphenylamine‐substitutedcarbazole fragments linked by a nonconjugated methylenebenzene unit is synthesized and tested in perovskitesolarcells. Synthesis of the investigated materials is performed by a simple two‐step synthetic procedure providing a target product in high yield. The isolated materials demonstrate good thermal
