| Abstract [eng] |
The development of the simple synthesis schemes of the organic semiconductors can have an important contribution to the advancement of the related technologies. In particular, one of the fields, where the high price of the hole‐transporting material may become an obstacle towards successful commercialization, is perovskite solar cells. In this work, we have synthesized enamine‐based materials that are capable to undergo cross‐linking due to the presence of the two vinyl groups. It was shown that new compounds can be thermally polymerized, making the films resistant to organic solvents. This can allow to use a wet‐coating process for the deposition of the perovskite absorber film, without the need for orthogonal solvents. Cross‐linked films were used in perovskite solar cells, and, upon optimization of the film thickness, the highest power conversion efficiency of 18.1% was demonstrated. |
