“…The studied compounds have direct band gap within energy range 1.36-2.24 eV. The energy gap of Si, CdTe, and CH 3 NH 3 PbI 3 compounds are 1.1, 1.44, and 1.6 eV respectively [41][42][43] Our findings indicate that the energy gaps of studied compounds (especially A 2 TlAsBr 6 ) fall within a comparable range to those of CdTe, and CH 3 NH 3 PbI 3 , suggesting their potential suitability for various optoelectronic applications.

We have investigated the structural, electronic, optical, and thermoelectric behavior of halide-based double perovskites A2TlAsX6 (A = K, Rb; X = Cl, Br) compounds to reveal their potential in various opto-electronic and thermoelectric applications using first-principle calculations. For the computation of the various properties of A2TlAsX6 (A = K, Rb; X = Cl, Br) compounds, we have used approximations available within density functional theory (DFT). The energy bands and density of states have been used to elucidate the electronic response of the studied compounds, while the interpretation of optical properties is presented in terms of dielectric tensor, absorption coefficient, reflectivity, refraction and energy loss spectra. The investigated compounds exhibit a direct band gap within the energy range of 1.36 to 2.24 eV, indicating the promising nature of these compounds for diverse optoelectronic applications. Moreover, thermoelectric properties such as the figure of merit, power factor, Seebeck coefficient, specific heat, electric and thermal conductivity have also been computed for the studied compounds. Our investigation unveils the remarkable optoelectronic characteristics of the studied perovskites, which can be attributed to their advantageous bandgap and highly effective light absorption capabilities. Furthermore, these perovskites showcase exceptional thermodynamic stability, elevated electrical conductivity, favorable figure of merit (ZT) values, and reduced thermal conductivities. These findings suggest their suitability for applications in optoelectronic devices and thermoelectric applications. In this study, it is found that A2TlAsBr6 compounds exhibit significant absorption in the visible spectrum, rendering them more favorable for optoelectronic applications compared to A2TlAsCl6 compounds. Conversely, for thermoelectric applications, the Cl-based perovskites studied show greater promise than their Br-based counterparts. The modified Becke–Johnson (mBJ) potential emerges as the most precise approach for analyzing the electronic, optical, and thermoelectric characteristics of A2TlAsX6 (where A = K, Rb; X = Cl, Br) perovskites, surpassing other approximations utilized in present study.

We report on the development of a multistacked configuration of a photonic cooler for implementation in sunny and arid regions. The optimized multistacking structure considers TiO x as a top layer, NiO x as the buffer layer, and Ag as a hot mirror (i.e., a reflective layer of the NIR light spectrum). The entire stacked layers were deposited in situ without breaking the vacuum. The oxide layers were grown reactively under an oxygen medium at a deposition pressure of 2 × 10 −4 Torr. The level of TiO x surface wettability was demonstrated to be controlled by the oxygen flow during the film growth process, which may additionally provide a self-cleaning property to the IR filters. By combining low refractive index layers (i.e., TiO x ) with the high refractive index of the metal oxides (i.e., NiO x ) along with the metal layers (i.e., Ag, Al), the photonic filtration (i.e., cutoff) of the infrared spectrum was successfully achieved while keeping the light transmittance of the visible (vis) light above 50%. Different structures with different thicknesses have been systematically assessed, including TiO x /NiOx/Ag, TiO x /NiO x /Al, TiO x /MoO x /Ag, and TiO x /MoO x /Al. Furthermore, numerical simulations were carried out using SCAPS-1D and OptiLayer software to evaluate the application of these filters on silicon solar cells, considering the experimental electrical and optical parameters for each explicit layer of the device. Our results confirm that the development of such coatings with a scalable thin film growth process may have a real commercialization potential due to their multifunctionalities such as IR filtering, antireflection coating in the vis range, and antisoiling properties.

This paper focuses on exploring new materials and structure as a means to increase the efficiency of solar cells. Since silicon is widespread on earth, it is desirable to study heterojunction solar cells made mainly of silicon and new materials. Therefore, ZnO/Si and TiO2/Si heterojunction solar cells were studied in this paper. First, the electrical and optical properties of ZnO and TiO2 were determined using the Perdew-Burke-Ernzerhof (PBE), PBE functional revised for solids (PBESol) and Perdew-Wang (PW91) functionals of the Generalized gradient approximation (GGA) in Density Functional Theory (DFT). The obtained results in various functionals are assessed and analyzed. It was found that geometric optimized structures of TiO2 and ZnO is mechanical stable. Accordingly, in all functionals, the effective mass of the electron in ZnO and TiO2 proved to be smaller than that of the hole. The mobility of electrons and holes in ZnO was calculated to be 430.72 cm 2 V -1 s -1 and 5.25 cm 2 V -1 s -1 respectively. In TiO2, it was 355.27 cm 2 V -1 s -1 and 46.38 cm 2 V -1 s -1 . When PW91, PBESol, PBE functionals were used, the dielectric constant was determined to be 11, 11.5, 8.5 for ZnO and 9.5, 10, 9 for TiO2, respectively. According to the DFT results, it was determined that ZnO and TiO2 are transparent and mainly n-type direct semiconductors. According to device simulation, the maximum short-circuit current of ZnO/Si and TiO2/Si heterojunction solar cells is 18 mA/cm 2 at a thickness of 80 nm and 15.3 mA/cm 2 at a thickness of 40 nm. Finally, the average fill factor of ZnO/Si and TiO2/Si solar cells was 0.73 and 0.76 respectively. So TiO2 can be used as a transparent contact and ZnO as an emitter layer in a silicon-based solar cell.
