Our Latest Article Published in ACS Applied Materials & Interfaces!

We are excited to share that our latest research article, led by Prof. Daniel Prochowicz in collaboration with Prof. Marcin Lindner from Institute of Organic Chemistry, PAS, has been published in the prestigious journal ACS Applied Materials & Interfaces. The paper, titled “T-Shaped-N-Doped Polycyclic Aromatic Hydrocarbons: A New Concept of Dopant-Free Organic Hole-Transporting Materials for Perovskite Solar Cells” revealed a new class of nitrogen-doped polycyclic aromatic hydrocarbons was developed as dopant-free hole transport materials (HTMs) for perovskite solar cells (PSCs). Through combined theoretical and experimental analysis, N-PAH23 showed enhanced π-π stacking and band alignment with the perovskite layer, reducing non-radiative recombination at the interface. This led to a high power conversion efficiency (PCE) of 20.39% and improved stability in N-PAH23-based devices, outperforming conventional spiro-OMeTAD-based HTMs. These findings highlight the potential of N-PAHs in advancing efficient and stable PSCs.
