权利人:COLORADO SCHOOL OF MINES
摘要:Polymer transport materials for application in perovskite solar cells capable of being tuned or manipulated to achieve desired properties, are provided herein. The present disclosure is directed to methods, systems, and compositions for achieving polymer transport materials (i.e., hole transport materials (HTMs)) with desirable properties such as solution processability, energy level tuning (i.e., adjusting), high thermal properties, tunable (i.e., adjustable) wettability, and perovskite defect passivation. In some aspects of the present disclosure, the synthesis of such HTMs may be implemented via relatively simple and inexpensive processes.

摘要:The organic semiconductor polymers relates to the synthesis of a carbazole-based ladder polymer. The synthesis of the ladder polymer includes forming a precursor conjugated polymer by Suzuki step growth polymerization of 2,7-dibromocarbazole with 1,4-dibromo-2,5-divinylbenzene, followed by end capping with 2-bromostyrene and 2-vinyl-phenylboronic acid. Then, the pendent vinyl groups are closed by ring-closing olefin metathesis to obtain the ladder polymer.

摘要:The present disclosure describes the synthesis, characterization, and purification of functionalized aromatic phosphonic acids (FAPAs) for use as hole extraction materials in perovskite solar cells and display devices. Embodiments of the present disclosure provide a method to prepare FAPAs with varying dipoles that can significantly improve the electronic properties of electrode materials used in displays and photovoltaic devices. The FAPA may be tuned for specific active layers. Aspects of the disclosure include phosphonic acid molecules that enhance bonding at the perovskite/substrate interface to create a strong hole extraction polymer retaining high efficiency and improving ultraviolet stability of perovskite solar cells by suppressing ion migration at the embedded interface.
