Abstract

Abstrak. Sel surya berbasis perovskite merupakan sel fotovoltaik generasi terakhir yang mampu memanfaatkan energi surya dengan efisiensi tinggi dan dapat difabrikasi melalui proses yang sederhana dan murah. Sejak diperkenalkannya perovskite solar cell (PSC), efisiensi konversi dayanya telah mencapai efisiensi di atas 23% dalam waktu yang relatif singkat diiringi dengan peningkatan publikasi ilmiah di bidang ini. Penggunaan semikonduktor ZnO sebagai Electron Transport Material (ETM) yang merupakan salah satu bagian utama dalam PSC mulai dilirik akibat proses pembuatan yang lebih sederhana dibandingkan TiO2. Seng oksida (ZnO) masih memiliki kelemahan yang dapat diatasi dengan penambahan ZnS untuk mengurangi rekombinasi pembawa muatan dari lapisan perovskite ke ETM. Tujuan dari artikel ini adalah untuk menyajikan tinjauan singkat tentang status terkini mengenai komposit ZnO/ZnS sebagai elektron transport material pada sel surya perovskit. Ulasan ini juga membahas peran penambahan ZnS dalam memperbaiki morfologi dalam ukuran nano dan sifat optik material sekaligus meningkatkan kinerja PSC beserta penjelasan mengenai mekanisme dasar operasi piranti untuk memberikan pemahaman yang lebih baik tentang sifat dari ZnO/ZnS sebagai ETM pada sel surya perovskit. Abstract. Perovskite-based solar cells are the latest generation of photovoltaic cells capable of utilizing solar energy at high efficiency and can be fabricated through a simple and inexpensive process. Since the introduction of the perovskite solar cell (PSC), its power conversion efficiency has reached efficiencies above 23% in a relatively short period of time accompanied by an increase in scientific publications in this field. The use of ZnO semiconductors as Electron Transport Material (ETM), which is one of the main parts of PSC, has begun to be noticed due to the simpler manufacturing process compared to TiO2. Zinc oxide (ZnO) still has a weakness which can be overcome by adding ZnS to reduce the recombination of the charge carriers from the perovskite layer to the ETM. The aim of this article is to present a brief overview of the current status of ZnO/ZnS composites as an electron transport material in perovskite solar cells. This review also discusses the role of addition of ZnS in improving morphology in nanosize and optical properties of materials as well as improving PSC performance along with an explanation of the basic mechanism of device operation to provide a better understanding of the properties of ZnO/ZnS as ETM in perovskite solar cells. Keywords: Perovskite solar cell, Composite, ZnO, ZnS dan Electron Transport Material.

Ferroelektrik juga diaplikasikan sebagai kapasitor. Material ferroelektrik buat dalam bentuk film tipis. Barium Zirconium Titanate (BZT) dengan komposisi BaZr0.4Ti0.6O3 dibuat menggunakan metode sol-gel. Substrat yang digunakan yaitu FTO yang telah di etching dan di lapisi BZT serta di annealing pada suhu 800°C selama 2 jam dengan kenaikan laju suhu annealing yaitu 5°C dan 10°C. Sampel di karakterisasi menggunakan XRD. Hasil karakterisasi XRD menunjukkan adanya puncak-puncak yang menandakan terdapat struktur kristal. Struktur kristal yang dihasilkan berada pada bidang 100  pada sudut 2θ = 22.78°, bidang 110  pada sudut 2θ = 32.17°, bidang 111 pada sudut 2θ = 38.42°, bidang 200 pada sudut 2θ = 47.73°. Struktur yang dihasilkan pada penelitian ini yaitu tetragonal dimana a = b = 3.91 nm dan c = 4.05 nm. Laju kenaikan suhu berpengaruh pada puncak Difraksi Sinar-X. Nilai FWHM untuk 5°C lebih kecil dari 10°C, ini menunjukan adanya kerapatan yang lebih besar saat di annealing dengan laju 5°C. Nilai ukuran kristal yang di dapat dengan kenaikan suhu 5°C dan 10°C pada bidang 100 yaitu 3.94 nm dan 3.22 nm. Ukuran kristal berbanding terbalik dengan nilai FWHM dimana laju kenaikan suhu annealing yang kecil menyebabkan ukuran kristal membesar. Abstract Ferroelectrics is a material that has spontaneous polarization and ability to change its internal polarization by using a suitable electric field. Ferroelectricsis also applied as a capacitor. The ferroelectric material is made in the form of a thin film. Barium Zirconium Titanate (BZT) with the composition BaZr0.4Ti 0.6O3 is prepared using the sol-gel method. The substrate used is FTO which has been etched and coated with BZT and annealed at a temperature of 800°C for 2 hours with a increase in the annealing temperature speed of 5°C and 10°C.Samples are characterized using XRD. The XRD characterization results show peaks indicating a crystal structure. The resulting crystal structure is in a plane 100 at an angle of 2θ = 22.78°, a plane 110 at an angle of 2θ = 32.17°, a plane 111 at an angle of 2θ = 38.42°, a plane 200 at an angle of 2θ = 47.73°. The resulting structure in this study is a tetragonal where a = b = 3.91 nm  and c = 4.05 nm. The speed at which temperature increases has an effect on the peak of the X-Ray Diffraction.The FWHM value for 5°C is less than 10°C which indicates a greater density when annealed at a speed of 5 °C. The value of the crystal size obtained with an increase in temperature of 5°C and 10°C in the  plane 100 is 3.94 nm and 3.22 nm. The crystal size is inversely proportional to the FWHM value where the small speed of the annealing temperature increase causes the crystal size to enlarge.Keywords: BaZr0.4Ti0.6O3 Thin Film,  Speed of Annealing Temperature Increase,  Sol-gel method, X-Ray Diffraction (XRD).

Abstract

 Abstrak. Dalam rangka mengurangi pemakaian bahan kimia berbahaya, kini telah mulai dikembangkan penggunaan bahan alami pada proses pembentukan nanopartikel. Pada penelitian ini, biosintesis nanopartikel ZnO dilakukan menggunakan ekstrak kulit Ananas comosus sebagai agen capping sekaligus agen pereduksi. Seng nitrat digunakan sebagai prekursor dari ion seng, sedangkan kulit nanas dibuat menjadi ekstrak untuk dimanfaatkan kandungan antioksidannya. Sampel ZnO dipelajari sifat fisisnya dari hasil karakterisasi X-ray diffraction (XRD), scanning electron microscopy (SEM) dan spektroskopi UV-Vis. Berdasarkan pola XRD, nanopartikel ZnO memberikan fasa kristal heksagonal wurtzite dengan ukuran kristal 14 nm. Morfologi SEM masing-masing sampel didapatkan berbentuk bunga atau micro-nanoflower dengan ukuran diameter rata-rata 510 nm dan 560 nm untuk sampel 0,01 M dan 0,025 M. Hasil spektrum absorbansi UV-Vis menunjukkan peningkatan puncak penyerapan cahaya dengan penambahan konsentrasi seng nitrat. Berdasarkan informasi sifat fisis ini, sampel ZnO berpotensi diaplikasikan sebagai material fotokatalis.Abstract. In order to reduce the use of hazardous chemicals, the use of natural ingredients has now been developed in the process of forming nanoparticles. In this study, biosynthesis of ZnO nanoparticles was carried out using Ananas comosus peel extract as capping agent and reducing agent. Zinc nitrate was used as a precursor to zinc ion. The physical properties of ZnO samples were studied from the characterization result of scanning electron microscopy (SEM), UV-Vis spectroscopy, and X-ray diffraction (XRD). The SEM morphology of each different sample was obtained in the form of micro-nanoflower with an average diameter  of 510 nm and 560 nm for 0.01 M and 0.025 M samples, respectively. The UV-Vis absorbance spectrum results showed an increase in the light absorption peak as  zinc nitrate concentration increased. According to the XRD pattern, the ZnO nanoparticles possessed an hexagonal wurtzite crystal phase with a crystal size of 14 nm. Based on this information on physical properties, the ZnO sample has the potential to be applied as a photocatalyst material.

Abstract

Nanotechnology is developing rapidly with a variety of synthetic materials, apart from the perceived work efficiency, which is also prioritized in terms of safety and non-toxicity. The synthesis that has the potential to be carried out based on these criteria is the type of Ag-doped ZnO nanoparticles. ZnO nanoparticles were prepared by a biosynthetic method using pineapple peel extract as a reducing agent. This study aims to look at the effect of adding Ag to ZnO nanoparticles. The percentage variation of Ag to ZnO is 1%, 3%, and 5%. The pineapple peel extract was mixed with 0.05 M (Zn(NO3)2)·6H2O and 0.05 M AgNO3 precursor solutions. The solution was heated at 80 °C for 2 hours. The results of the biosynthesis were characterized using Spectroscopy UV-Vis, X-ray diffraction (XRD), and scanning electron microscopy (SEM). The UV-Vis spectrum informs that strong absorption occurs at wavelengths below 400 nm. The maximum absorption is shown by sample ZnO:Ag 3% and the minimum absorption is shown by the pure ZnO sample. XRD characterization showed that the formation of seven diffraction peaks occurs at a diffraction angle (2θ) of: 31.729°; 34,397°; 36,214°; 47,467°; 56,541°; 62.831°; and 67.922°. The SEM results showed surface morphology of ZnO and ZnO:Ag 1% samples are floral and spherical, while ZnO:Ag 3%  and ZnO:Ag 5% samples are coral rocks.

Abstract

Visualization of crystal structures and simulation of X-ray diffraction patterns of perovskite ceramic was successfully performed by VESTA software programs. The purpose of this research is to obtain the relation of lattice parameter, and composition to the diffraction pattern. The software program produces crystal structure information and a representative X-ray diffraction pattern for the ceramic materials. The program needs several input parameters such as the coordinates of each constituent atom, lattice parameters, and space symmetry. The obtained output of the software program are in the form of diffraction pattern graph and crystal structure data which gives the description of the profile and type (phase) of ceramic material. The results showed that the peak position and intensity of the diffraction pattern are influenced by the arrangement of  the atoms within the unit cell. The addition of impurity atoms such as Sr on the Ba side in BaTiO3 causes the BaTiO3 structure changes from Orthorombic (a≠b≠c) to Tetragonal (a=b≠c) structure. Based on the simulation, it can be predicted that the critical concentration of the change of structure occur at Sr concentration about 0.4.

Abstract

In early 2020, the world was shocked by the outbreak of new pneumonia that started in Wuhan, Hubei Province which then spread rapidly to more than 190 countries and territories. This outbreak is named coronavirus disease 2019 (Covid-19) which is caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). People are not aware that their hands are often contaminated with bacteria and viruses during their activities. One of the simplest ways and can be done to prevent this is to wash your hands using soap or antiseptic, hand sanitizer. Washing your hands can reduce the number of bacteria by up to 58%. The advantages of hand sanitizers can kill germs in a relatively fast time. The active ingredients of hand sanitizers are generally alcohol group compounds with a concentration of ± 60% to 80% and the phenol group (triclosan) so that they have a mechanism of action by denaturing and coagulating cell protein germs. Therefore, making hand sanitizers in simple stages can be done alone in community service activities. This service aims to find out how high public awareness is in dealing with the Covid-19 outbreak in everyday life. Evaluation of the service activities that will be carried out is to see how many people are aware of the importance of protecting themselves and the environment and maintaining distance in order to break the chain of spreading the virus.

Abstract

Sulfur-doped zinc oxide (S-ZnO) nanorod has been successfully synthesized via the seed-mediated hydrothermal method with different sulfur concentrations (0%, 1%, 2.5%). This research aims to study the influence of the concentration of sulfur on the structure, morphology, and optical properties of ZnO as a promising material in a wide range of applications. Crystal structure, morphology, and optical properties of the samples were characterized using X-Ray Diffraction (XRD), Field Emission Electron Scanning Microscopy (FESEM), and UV-Vis Spectroscopy, respectively. The XRD pattern shows the strongest peak at 2θ = 34.43° for crystal orientation of (002). The crystallinity properties of the S-ZnO sample are higher compared to the ZnO sample. The FESEM images of the 1% S-ZnO sample exhibit the highest nanorod density arrangement. The optical absorbance of the higher sulfur dopant possesses a higher optical absorption peak on the UV-Vis spectrum. The results indicate that S doping to ZnO can alter the structural, morphological, and optical properties of ZnO.
