Reducing the use of fossil fuels and the generation of renewable energy have become extremely important in today. A climatic emergency is being experienced and society is suffering due to a high incidence of pollutants. For these reasons, energy harvesting emerges as an essential source of renewable energy, and it benefits from the advancement in the scope of solar and thermal energy which are widely abundant and usually wasted. It is an option to obtain energy without damaging the environment. Recently, energy harvesting devices, which produce electricity, have been attracting more and more attention due to the availability of new sources of energy, such as solar, thermal, wind and mechanical. This article looks at recent developments in capturing energy from the sun. This literature review was performed on research platforms and analyzes studies on solar and thermal energy capture carried out in the last four years. The methods of capturing solar energy were divided according to how they were applied in civil engineering works. The types of experiments carried out were the most diverse, and several options for capturing solar energy were obtained. The advantages and disadvantages of each method were demonstrated, as well as the need for further studies. The results showed that the materials added to the components obtained have a lot of advantages and could be used in different energy capture types, such as photovoltaic, thermoelectric generators, pyroelectricity and thermometrical. This demonstrates that the capture of solar energy is quite viable, and greater importance should be given to it, as the number of research is still small when compared to other renewable energies.

“…Enhanced photovoltaic properties in polycrystalline BFO thin films with rhombohedral perovskite structure deposited on fluorine doped tin oxide substrates and ferromagnetic of Co‐doped BiFeO 3 based ferroelectric thin films have been studied by References 16 and 17. On the other hand, the effect of laser fluency during film growth on the ferroelectric‐photovoltaic applications of BFO thin films grown on transparent glass substrates coated with indium tin oxide has been investigated 18 …”

Summary Monte Carlo simulations and the full‐potential linearized augmented plane wave (FP‐LAPW) method in the framework of density functional theory (DFT) are applied to investigate the quantum efficiency, ferroelectric, and photovoltaic properties. We have used the generalized Perdew Burke Ernzerhof gradient approximation (PBE‐GGA) as well as the Becke‐Johnson modified exchange potential (TB‐mBJ) to correct the gap's energy. The gap energy results of 2.5 eV obtained using mBJ are reasonable compared to the available experimental data (2.5 eV). The difference energy ∆E between the magnetic configurations EFM and EAFM of Fe was calculated. The BiFeO3 possesses the insulating ground state and G‐type antiferromagnetic ordering. The value of the magnetic moment was compared with the values obtained using experience and theory. The quantum efficiency (EQE), the short‐circuit current and open circuit voltage are investigated using ab‐initio calculations. The polarization, dielectric susceptibility and hysteresis loops are investigated using the Monte Carlo simulations for several thin films of BiFeO3.

Present work reports the growth of BFO/WO 3 bilayer thin film structures over Silicon, corning and ITO coated glass substrates. BFO layer in BFO/WO 3 bilayer structure was deposited using Pulsed Laser deposition (PLD) technique at optimized laser energy (200 mJ) while WO 3 nanostructured layer was deposited using rf-magnetron sputtering technique at varying glancing angle from 65 to 80 . For the realization of MBM (metal-bilayer-metal) device, top Gold (Au) electrodes have been deposited using thermal evaporation technique. The BFO/WO 3 bilayer structure fabricated at 70 glancing angle exhibited the saturation (P s ) and remnant (P r ) polarization as 45.45 μC/cm 2 and 21.52 μC/cm 2 respectively, which are appreciably higher than the earlier reports for pure BFO thin films. Enhanced energy storage characteristics were obtained in Au/BFO/WO 3 /ITO structure fabricated at 70 glancing angle with chargedischarge efficiency (63%) and enlarged recoverable energy density (467 mJ/cm 3 ). Achieved results indicate the utilization of fabricated Au/BFO/ WO 3 /ITO structures towards high energy storage applications.
