“…The choice of materials and engineering for the interlayers is a key aspect of TSC optical design and optimization, as it influences factors such as the charge recombination, optical absorption, and series resistance. The researchers have achieved a PCE of 23.6-30.8% with Jsc 11.3 mA/cm 2 , using materials such as ZnO [92,[95][96][97][98][99], ITO [92,96,100,101], FTO [92,102,103], and MoOx [30] as a transparent conducting oxide and interlayer between sub-cells. Furthermore, engineered interlayers can also be used between sub-cells for light management.…”

Tandem solar cells (TSCs) perform a better adaptation of the incident photons in different-energy-level bandgap materials, and overcome the Shockley–Queisser limit, but they require advanced control over the management of light for optimum performance. Nanomaterials and nanostructures offer a vastly improved control over the management of light. Through different optimization techniques, researchers can gain valuable insights regarding the optimization of various parameters of nano-optical designs. Over the past years, the number of studies on this topic has been continuously increasing. The present study reviews various current state-of-the-art optical designs, and provides an overview of the optimization techniques and numerical modeling of TSCs. This paper collected and analyzed different studies published within the years 2015–2022, using systematic literature review techniques, such as specific protocol screening and a search strategy. Seven different optical designs were extracted, along with their advanced local and global optimization methods, which offer a solution to the optical limitations of TSCs.

“…Synthesis of crystals with specific morphology and size has become a hot topic since the properties of a composite material rely heavily on its micro-nano structures. [1][2][3] Zinc oxide (ZnO) stands out among these materials due to its variable morphologies and remarkable optical properties, finding applications in catalysts, [4] photoelectric devices, [5] solar cells, [6] cosmetic industry, [7] antimicrobial agents, [8] rubber, [9] and so forth. Up to date, ZnO with various morphologies, such as wires, [10] snowflakes, [11] cylinders, [12] tubes, [13] stars, [14] dendrite sheets, [15] plates, [16] dumbbells, [17] disks, [18] and so on, have been successfully prepared as a functional filling employed in many occasions.…”

ZnO crystals are employed in numerous industries, but precisely controlling their morphologies is still challenging. In this work, a continuous flow process for synthesizing ZnO crystals is developed based on the co‐precipitation method. ZnO crystals at different morphologies, including needle‐like, rod‐like, flower‐like, spindle‐like, and nanospheres, are successfully prepared at low temperature. The influence of reaction temperature, pH value, ZnCl2 feeding concentration, and reaction time on the morphology, size, and purity of ZnO crystals is systematically investigated. The results of X‐ray diffraction show that the high‐purity ZnO can only be produced when the reaction temperature is above 75 °C. The band gap energies of ZnO evaluated by UV–vis diffuse reflectance spectroscopy increase with the synthesis temperature. According to scanning electron microscope (SEM) findings, the size of ZnO crystals is regulated by controlling the reaction time. Interestingly, the morphology of ZnO crystals is changed from 1D to 3D structure by controlling the feeding concentration of ZnCl2. Moreover, a concentration difference mechanism of ZnO crystal morphology evolution is proposed by monitoring the real‐time concentration of free Zn2+ ions.

“…ZnO is one of the most efficient semiconductor oxide materials found as a zincite mineral in wurtzite form, and it possesses a hexagonal crystal arrangement [4,5]. The ZnO (bandgap 3.4 eV) has been extensively studied recently due to its industrial applications, such as in LEDs [6][7][8][9], biosensors [10][11][12][13], photodetectors [14,15], and solar cells [16,17]. Modern computational techniques [18,19] and experimental highpressure equipment [20] have enabled researchers to achieve a transition in the wurtzite ZnO structure towards new phases accompanying extraordinary properties under pressure.…”

Pressure-induced phases of ZnO have attracted considerable attention owing to their excellent electronic and optical properties. This study provides a vital insight into the electronic structure, optical characteristics, and structural properties of the AsTi (Bi) phase of ZnO under high pressure via the DFT-based first-principles approach. The phase transformation from BN(Bk) to the Bi phase of ZnO is estimated at 16.1 GPa using local density approximation, whereas the properties are explored precisely by the hybrid functional B3LYP. The electronic structure exploration confirms that the Bi phase is an insulator with a wider direct bandgap, which expands by increasing pressure. The dielectric function evidenced that the Bi phase behaves as a dielectric in the visible region and a metallic material at 18 eV. Optical features such as the refractive index and loss function revealed the transparent nature of the Bi phase in the UV range. Moreover, the considered Bi phase is found to possess a high absorption coefficient in the ultraviolet region. This research provides strong theoretical support for the development of Bi-phase ZnO-based optoelectronic and photovoltaic devices.
