“…The reason for the broadening may be associated with the reduce in the crystalline size. The decrease of crystalline size may result in an increase in the grain boundaries and so increase the amount of defects in the structure [2,13]. The recorded (200) and (111) peak intensities of the coatings are shown in Table 1.…”

Saccharin which so-called as benzoic sulfimide is an artificial sweetener. In this paper, nanostructured lead sulfide (PbS) thin films were produced in the presence of additive known as saccharin via chemical bath deposition (CBD). Effect of the saccharin content on the morphological, optical and structural properties of the films has been investigated. Lead sulfide (PbS) films that included additive were prepared at five different concentrations of saccharin (from 0 to 5%). The fabricated samples were characterized by surface roughness, scanning electron microscopy (SEM), X-Ray diffraction and UV-vis spectroscopy. It was found that the presence of saccharin highly affected the optical and structural properties of PbS thin films. According to the X-Ray diffraction results, crystallite size values of the films decreased from 12.88 to 5.25 nm with increasing of saccharin content. UV-vis measurements showed that both the band gap and transmission properties of the films increased as a result of increasing saccharin concentration. Further, Surface roughness measurements exhibited that average surface roughness was diminished with increasing saccharin content. As a result, it has been found that the presence of saccharin in growth solution played a significant mission in adjusting the main physical properties of the samples. Sakarin İlavesiyle Cam Altlıklar Üzerine CBD ile Büyütülen PbS Filmlerin Morfolojik, Yapısal ve Optik Özelliklerinin Modifikasyonu Anahtar KelimelerYüzey pürüzlülüğü, Kurşun sülfür, Sakarin, Kimyasal banyo depolama Özet: Benzoik sülfimid olarak da bilinen sakarin yapay bir tatlandırıcıdır. Bu makalede, nanoboyutlu kurşun sülfür (PbS) ince filmler sakarin olarak bilinen katkı maddesi varlığında kimyasal banyo depolama (CBD) ile üretilmiştir. Sakkarin miktarının filmlerin morfolojik, optik ve yapısal özelliklerine etkisi araştırılmıştır. Katkı maddesi içeren kurşun sülfür (PbS) filmler sakarinin beş farklı konsantrasyonunda (%0 dan %5'e) hazırlanmıştır. Üretilen numuneler yüzey pürüzlülüğü metodu, taramalı elektron mikroskopisi (SEM), X-Işını kırınımı ve UVvis spektroskopisi ile karakterize edilmiştir. Sakarin varlığının PbS ince filmlerin optik ve yapısal özelliklerini oldukça etkilediği bulunmuştur. X-Işını kırınımı sonuçlarına göre, filmlerin kristal boyutu değerleri sakarin içeriğinin artmasıyla 12.88 nm'den 5.25 nm'ye düşmüştür. UV-vis ölçümleri artan sakarin konsantrasyonunun bir sonucu olarak hem filmlerin bant aralığının hem de geçirgenlik özelliklerinin arttığını göstermiştir. Ayrıca, yüzey pürüzlülüğü ölçümleri sakarin miktarının artmasıyla ortalama yüzey pürüzlülüğünün azaldığını göstermiştir. Sonuç olarak, büyütme çözeltisinde sakarin varlığının numunelerin temel fiziksel özelliklerini ayarlamada önemli bir görev üstlendiği tespit edilmiştir.

Summary Silver (Ag)‐doped PbS (PbS:Ag) thin films of 616 to 745 nm in thickness were prepared on glass substrates via cost‐effective nebulizer spray method by adding different Ag levels from 2% to 8% at 200°C. For solar cell applications, the effect of Ag doping concentration on structural, morphological, optical, photoluminescence, and electrical chattels of PbS thin film has been studied. X‐ray diffraction pattern confirmed the polycrystalline behavior of the prepared PbS:Ag films with cubic crystalline nature. The crystalline size and texture coefficient were increased by increasing Ag doping concentration. From the morphological studies by scanning electron microscope (SEM) and atomic force microscope (AFM), the grain size of the films and surface roughness values were increased for the increase in Ag doping concentration. EDS spectra confirmed the existence of Ag, Pb, and S elements in the select 6% Ag‐doped PbS film. Peaks related to silver oxide started to emerge at 6% of Ag doping level. The optical direct band gap value was reduced from 1.51 to 1.17 eV for Ag doping from 2% to 6% and thereby slightly increased as 1.79 eV for 8% Ag doping level. For all PbS:Ag films, the photoluminescence spectrum emitted a strong near band edge (NBE) emission at approximately 580 nm, meaning better optical quality. Hall effect measurements evidenced that Ag doping provides enhancement on the characteristics of mobility, carrier concentration, and resistivity with p‐type conducting nature. The observed high carrier concentration and low resistivity values were 4.32 × 1014 cm−3 and 80 Ωcm, for 6% Ag‐doped PbS film. The FTO/CdS/PbS:Ag heterostructure solar cell was formed from 6% Ag‐doped film.
