So, the research goals have directed on developing novel renewable-energy technologies as suitable alternative sources of the traditional energy that addresses these problems. Photovoltaic based solar cells technology gives sustainable solutions and depends on inorganic materials with specific properties. Among this family, halide perovskites (MBX3) have been investigated during the last five years. Besides studying their unique properties as flexible structures, high stability, tunable semiconductor band-gap (Eg 2.50 eV), high charge-carrier mobility and large optical absorption, research also seek for promising and multifaceted electroptical applications that give an amazing power efficiency (~24.0 %) in photovoltaic technology. The current challenge is to synthesis MBX3 materials provide suitable properties, include notable chemical stability at high temperatures, high electrical power efficiency, broad emission and tunable semiconducting Eg. Motivated by the site substitution effect, we extended this concept to build a series of cesium-metalloid MBX3 (M1+ = Cs; B2+ = Si, Ge, Sn, Pb; X– = Cl, Br, I), and investigate their structural, stability and optoelectronic properties. We expect these investigations will provide inspiration for an innovation of such MBX3 materials in photovoltaic applications.","PeriodicalId":54394,"journal":{"name":"Journal of Ovonic Research","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42145177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The magnetic properties Viz; Faraday effect and the Verdet constant at wavelength of laser beam (λ = 632 nm) were measured. The prepared sample with doped Er3+ has the highest value of Verdet constant (= 0.104min/G.cm) which depends on the polarizability of Er3+ ions. Moreover, the optical properties of present glass estimated by using UV-Vis-NIR spectroscopy. The oxygen-packed densities, molar volumes, the polarizability of the oxygen molar volume, the linear refractive index (n), third-order nonlinear susceptibility, (3)  , and nonlinear index (n2) of produced glasses were evaluation. It was found that the linear refractive index decreases otherwise the optical energy gap increased with doped Er3+ ions in the glasses network. Also, the Vickers microhardness increase with increasing Er2O3 in the glass matrix.

The sample were sintered at 900 ℃ for 5h. The structural, electrical, dielectric and magnetic properties of all the prepared samples were characterized by XRD, SMU2401, UV-Vis and FTIR. The powder X-ray diffraction patterns of all the prepared samples confirmed the formation of single-phase cubic spinel structures. These samples further characterized for the electrical properties by using two-probe type method. The DC resistivity of all the ferrite composition decreased as the temperature increased, showing their semiconductor nature. UV-Vis and FTIR confirmed the substitution of nickel in Cu-Co-Zn-Ce ferrites. From UV-Vis it is observed that the optical band gap changes from 3.9 eV to 5.3 eV with addition of Ni. FTIR analysis revealed that a strong variation on tetrahedral absorption frequency band is present which is due to the replacement of Ni on Cu.

The XRD confirms that the films are polycrystalline in nature with hexagonal wurtzite crystal structure with (002) plane as preferential orientation. The various parameters such as crystallite size, micro strain, and dislocation density were calculated from X-ray diffraction. HR-SEM images show smooth, tiny grains and dense morphology. The PL studies exhibits two emission peaks one at 389 nm corresponding to band gap excitonic emission and another located at 490 nm due to the presence of singly ionized oxygen vacancies. The UV-Vis-NIR spectrometer confirms the possibility of good transparent ZnO films with an average transmission of about ~85-95% in the visible region and optical band gap shifted from 3.37 eV to 3.2 eV with increase in temperature and which is supported by PL study.
