Muhammad Ans has successfully published his first PhD paper in Advanced Science as the first author. Congrats!

We are thrilled to announce that our latest research article,  led by Prof. Daniel Prochowicz in collaboration with Prof. Emre Guzel from Sakarya University of Applied Sciences, Sakarya, Türkiye, has been published in the prestigious journal Advanced Science. The paper, titled “Revealing the Impact of Aging on Perovskite Solar Cells Employing Nickel Phthalocyanine-Based Hole Transporting Material” revealed the effect of aged Bis-PF-Ni HTM on the overall performance of PSCs. In this work, for the first time the effect of aging the typical n-i-p PSCs employing nickel phthalocyanine (coded as Bis-PF-Ni) solely as dopant-free HTM is investigated and as an additive in spiro-OMeTAD solution. We found that the prolong aging of these devices at dry air condition (RH = 2%, 25 °C) is beneficial for the improvement of their performances. The results show that for an optimized concentration of Bis-PF-Ni the PCE of the device increases from an initial 7.04% to 13.94% after 21 days of storage. In addition, the self-enhancement in the PCE was also observed in the case of the addition Bis-PF-Ni to the spiro-OMeTAD solution, where the PCE increased from 13.78% to 19.70% upon aging. The observed self-enhancement of the PCE was attributed to the enhanced conductivity, better band alignment of Bis-PF-Ni, reduced trap-assisted recombination, and improved charge transport. The devices demonstrated superior ambient and thermal stability.
