“…On the surface of MAPbBr 3 , the empty Pb site was not replaced by the high value of W ions. The W atom bonds with the inner MAPbBr 3 atoms, causing the D to be lowered as a result [29,30]. These findings were consistent with previously published material showing that D is lowered when divalent/ trivalent ions are doped into the MAPbBr 3 structure [31,32].…”

Organic-inorganic hybrid halide perovskites have shown to be viable semiconductor materials, as the absorber layer of solar cells. Unfortunately, the polycrystalline qualities of perovskite films result in nonuniform coverage or a high recombination rate, which weakens the photoelectric capabilities of thin films. Here, the pure and tungsten (W)-doped methylammonium lead bromide (CH3NH3PbBr3 or MAPbBr3) films are deposited to FTO-glass substrates using the sol-gel spin coating method. The W-doping causes the nucleation and crystallization processes, which then have an impact on the film's characteristics. It is discovered that the introduction of tungsten metal significantly enhances the quality of the perovskite film, resulting in larger grain sizes, lower band gap energy, and shorter recombination lifetimes, increasing the power conversion efficiency of perovskite thin film solar cells.

In this study, solar cells based on pure Cs 2 AgBiBr 6 and Al-doped metal were fabricated using the sol−gel spin-coating technique. X-ray diffraction (XRD) analysis confirmed the formation of cubic-structured films for both pure and Al-doped. Notably, the grain size of Al-doped Cs 2 AgBiBr 6 was observed to be larger than that of its pure counterpart. The optical properties of these films were investigated using UV−vis spectroscopy, revealing essential parameters such as the bandgap energy (E g ), refractive index (n), extinction coefficients (k), and dielectric constant. While the pure film exhibited an E g of 1.91 eV, the Al-doped film demonstrated a slightly lower E g of 1.82 eV. Utilization of these films in solar cell fabrication yielded intriguing results. The J−V curve shows that the pure solar cell displayed a short-circuit current density (J sc ) of 5.01 mA/cm 2 , a fill factor (FF) of 0.67, an open-circuit voltage (V oc ) of 0.89 V, and an efficiency of 3.02%. Al doping led to improvements, with an increase in V oc to 0.91 V, FF to 0.71, and J sc to 5.29 mA/cm 2 . Consequently, the overall efficiency surged to 3.40%, marking a substantial 12.5% enhancement compared with the pure solar cell. These findings underscore the efficacy of Al doping in enhancing the performance of Cs 2 AgBiBr 6 -based solar cells.

“…When “ n ” is large, it means that a substance is optically dense and that light travels more slowly through it. 66,67 Therefore, when more light strikes the material, a greater number of electrons will emit. As a result, the solar cell's current density will grow, ultimately improving its efficiency.…”
