Abstract Inkjet‐printing is considered an emerging manufacturing process for developing perovskite solar cells (PSCs) with low material wastes and high production throughput. Up‐to‐now, all case studies on inkjet‐printed PSCs are based the exploitation of toxic solvents and/or high‐molarity precursor inks that known to enable development high‐efficiency photovoltaics (PVs). The present study provides a new insight lower‐toxicity, performance stable (for more than 2 months) inkjet‐printable...

"Polymer-in-salt" electrolytes are special conductive materials that demonstrate much higher conductivity compared to the conventional "salt-in-polymer" electrolytes. However, up-to-now, they found unsuitable for dye-sensitized solar cells (DSSCs) application, mainly because lead increased charge recombination rate. The present paper demonstrates development and application in DSSCs of polymer blend utilize features "polymer-in-salt" electrolytes, while aforementioned drawback is overcome....

Up until now, the vast majority of perovskite solar cells (PSCs) have relied on spin-coating precursor solution under inert fully controlled conditions, with performance that are developed by alternative techniques and an ambient atmosphere to lag far behind. This impedes technology transfer from laboratory industrial large-scale production; thus, investigation new scalable should be thoroughly considered. The present work constitutes one few investigations application inkjet-printing as...

Abstract Raw and modified fibrous clay minerals palygorskite (Pal) sepiolite (Sep) were tested for their ability to remove ammonium from polluted water. Palygorskite underwent thermal treatment at 400 o C (T-Pal T-Sep respectively). thermally treated samples characterized using XRD, SEM, BET, FT-IR, TGA, zeta potential XRF.
