“…Metal oxides have unique mechanical and electrical properties, making them easy to synthesize and design, and they are ecofriendly and have a wide band gap [4]. In this study, we investigate the effect of varying the thickness of p-type CdTe, temperature, and band gap on the efficiency of n-type TiO2 and p-CdTe heterojunction solar cells using Solar Cell Capacitance Simulator (SCAPS-1D) software.The thickness of the absorber layer is a crucial factor in solar cells as it directly affects cell performance [5].…”

This study presents a numerical analysis of p-type CdTe and n-type TiO2 heterojunction solar cells. The simulations were conducted using SCAPS-1D software to investigate the effects of varying the thickness of the p-type CdTe layer, the temperature, and the band gap on the efficiency of the solar cell. The results show that the efficiency of the solar cell increases from 16.81% to 18.28% as the thickness of the p-type CdTe layer is varied from 1.0 to 5.0 µm and decreases from 17.95% to 11.67% as the temperature is varied from 300 K to 400 K. The efficiency also increases from 15.29% to 19.26% as the band gap is varied from 1.40 eV to 1.55 eV. For the p-CdTe/n-TiO2 heterojunction solar cell, the optimized absorber layer thickness is 3 µm, and the optimized temperature and band gap are 300 K and 1.5 eV, respectively. At these optimized parameters, the highest efficiency (ⴄ) % achieved was 17.95%, with a VOC of 0.766 V, JSC of 27.75 mA/cm2, and FF of 84.39%. These results provide theoretical guidelines for fabricating efficient p-CdTe/n-TiO2 heterojunction solar cells.

“…Therefore, HMFs are regarded as ideal candidates for spin current sources. Amongst different classes of HMFs, the Co- [8,9] and Fe-based [10,11] Heusler compounds have attracted most interests because of their half-metallicity, large magnetic moment and high Curie temperature. * Author to whom any correspondence should be addressed.…”

The structural and magnetic properties are important parameters for spintronic applications of Heusler compounds. The Co2FeAl and CoFe2Al alloys are considered as the representatives of the regular and inverse Heusler structure, respectively. Here, we present a systematic study of the structural and magnetic properties of Co3-xFexAl (x = 1 ~ 2) Heusler thin films grown on MgO (001) substrates. The lattice parameters and magnetic properties, such as magnetic coercivity, saturated moment and four-fold magnetic anisotropy constant, display different change trends in the Co-rich and Fe-rich regions, which suggest that magnetic properties have relevance to the Heusler structures. Our findings give a better understanding of the Heusler structures and magnetic properties, which is helpful for developing spintronic applications.

“…The magnetocrystalline anisotropy of the alloy is weak due to the symmetric cubic structure, hence, PMA cannot be exhibited in the individual alloy films. It has been revealed that PMA can be built in lots of Co-based Heusler alloys such as Co 2 (Fe,Mn)Al and Co 2 Fe(Mn.Al)Si, sandwiched by MgO and heavy metals [22][23][24][25][26][27][28][29][30]. The PMA in the structures is supposed to originate from the orbital hybridization or alloying effects at the interfaces [31,32].…”

A series of Co 2 FeSi (CFS)/MgO heterostructures with Pd and Ta buffers are fabricated by sputtering method. Perpendicular magnetic anisotropy (PMA) with energy density of ∼1 × 10 6 erg/cm 3 is demonstrated in the annealed heterostructures deposited onto two heavy metal buffers. Pronounced influence of buffer layers on the magnetic and interfacial PMA properties is observed. Thicker magnetic dead layer and lower saturation magnetization are found in annealed Ta-buffered CFS/MgO heterostructure in contrast to Pd-buffered one. Wide window of MgO thickness exhibiting PMA is witnessed in the Pd-buffered heterostructure, in line with the enhanced PMA. PMA is shown to be insensitive to buffer thickness and is identified to dominantly originate from the heterostructure interface. Our results provide some useful information for design and integration of next-generation perpendicular spintronic devices based on CFS/MgO heterostructures.
