The surface-adsorbed iodine functionalized titania aerogel, designated as AI, while the lattice incorporated iodine and potassium ions in the titania aerogel and labeled it LI. The LI-based photoanode demonstrated an improved dye loading capacity of 0.43 µmol/mg and a significantly higher device efficiency of 4.34%, in contrast to the AI-based device, which achieved an efficiency of 1.66%. The spectroscopic analysis showed notable broadening and redshift in the absorption spectra for LI, suggesting robust electronic coupling and dye aggregation, which enhanced photon absorption and electron injection efficiency. Electrochemical impedance spectroscopy revealed a reduced charge transfer resistance (RCt = 29.5 Ω) and an increased electron lifetime (τn = 27.4 ms) for the LI-based DSSC, leading to enhanced interfacial charge transport and minimized recombination. The findings underscore the importance of the photoanode’s surface characteristics and the dyes’ aggregation for improving the performance of dye-sensitized solar cells.

Despite the persistence of recombination losses and stability issues, MAPbI2Br remains a viable choice due to its bandgap of around 1.8 eV. The objective of this study is to examine the process of introducing 6% chromium (Cr) into MAPbI2Br in order to address the aforementioned challenges. X-ray diffraction (XRD), current-voltage (J-V), and ultraviolet-visible spectroscopy (UV-vis) studies have demonstrated improved structural, optical, and photovoltaic characteristics of perovskite films doped with 6% Cr. The observed decrease in bandgap (from 1.99 to 1.94 eV) as the crystal size grows (from 21.45 to 32.09 nm) may be attributed to quantum size effects. The band structures of electronic materials undergo changes as the crystal size increases and the confinement of electrons decreases, leading to alterations in the bandgap energy.

After designing the nanobud structures, quantum calculations were performed to determine their electrical and optical structural characteristics. Finally, the possibility of using nanobuds as ammonia absorbers and their efficiency in comparison with graphene and boron nitride were investigated. As a result of the calculations, it was shown that the imaginary frequency was not observed in the calculated IR spectrum of the designed nanobuds and the calculated coherent energy for these structures also confirmed the possibility of their formation. Calculation of the electrical properties of the designed nanobuds showed that their electrical properties are similar to graphene, indicating the presence of B12N12 does not have a great effect on the electrical properties of the nanobuds. Also, it was shown that the nonlinear optical properties calculated for the nanobuds are not only similar to graphene, but also better than graphene. Also, the absorption of visible and ultraviolet light by nanobuds is more similar to graphene, and even in some cases, the number of absorption lines for nanobuds is more than that of graphene. Finally, the calculations showed that unlike graphene, which is not a suitable absorbent for ammonia, the designed nanobud structure is suitable absorbent for ammonia molecules.
