Two donor-π-spacer-acceptor (D-π-A) organic dyes were designed as photochromic with the same π-spacer and acceptor but different donors, based on their electron-donating strength. Various structural, electronic, optical properties, chemical reactivity parameters, certain crucial factors that affect short-circuit current density (Jsc) open circuit voltage (Voc) investigated computationally using functional theory time-dependent theory. The trans-cis isomerization of these azobenzene-based its...
Abstract Naturally abundant dyes are very attractive for the development of dye-sensitized solar cells (DSSCs). Hydroxycinnamic acid derivatives, such as caffeic ( CA ), ferulic FA and p -coumaric PA were considered selective harvesting ultraviolet A (UVA) (315–400 nm) photons. Their spectroscopic electrochemical properties investigated both theoretically experimentally. They further successfully adopted photosensitizers in UV-selective visibly transparent DSSCs, which exhibited a power...
A series of donor⁻π-conjugated spacer⁻acceptor (D⁻π⁻A) organic dyes featuring an azobenzene spacer were designed as chromic and investigated computationally. The electron-donating strength was modified by introducing units to the donor side. In particular, trans⁻cis isomerization azobenzene-based its effect on optical electronic properties further scrutinized. both trans cis conformers, a gradual increase in promoted natural charge separation between acceptor moieties, thereby allowing...
Abstract We report the facile synthesis of photochromic donor‐π‐acceptor (D‐π‐A) dyes featuring an azobenzene spacer with diphenylamine and dimethylamine as donor residues (DPAC DMAC). also investigate spectroscopic electrochemical properties these their application to dye‐sensitized solar cells (DSSCs). The trans ‐ cis isomerization bridge permits regulation photovoltaic behaviour in DSSCs containing iodine‐ cobalt‐based redox electrolytes. iodidie/triiodidie shuttle is suitable for...
Abu sekam padi mengandung 80% silika sehingga dapat dimanfaatkan sebagai bahan baku dalam sintesis nanosilika. Pada penelitian ini dilakukan nanosilika dari abu dengan variasi jenis asam yaitu HCl, H2SO4, dan H3PO4 konsentrasi masing-masing 3M. Nanosilika diperoleh mereaksikan natrium silikat yang melarutkan larutan NaOH 2,5 M kemudian proses sol gel katalis hingga pH 7. Berdasarkan hasil posfat ukuran morfologi permukaan 40 sampai 60 nm. dihasilkan sulfat (H2SO4) menghasilkan luas volume...
Tujuan yang diharapkan dari penelitian ini adalah ingin menganalisis persediaan bahan baku optimal dibutuhkan dengan menggunakan metode Economic Order Quantity (EOQ), berapa besar pengaman (Safety stock), kapan waktu tepat untuk melakukan pemesanan kembali (reorder point), total atau Total Inventory Cost (TIC). Jenis digunakan kuantitatif deskriptif. Teknik pengumpulan data dalam wawancara, observasi, dan dokumentasi. Penelitian hasil perhitungan dilakukan menunjukkan bahwa setiap tahunnya...
