“…Conventional NWs have a circular shape. Nevertheless, the design flexibility using mask etching technology enables the fabrication of NWs of different shapes, such as triangular, square, or hexagonal shapes, and even can be more exotic such as branched NW, 37 or quad‐crescent NW, 38 flower‐shaped NW, 39 and the moth‐eye NW 40 . In this work, the authors first discuss the effect of shapes by analyzing the optical performance of NWs via the finite difference time domain (FDTD) method 41 using the Lumerical FDTD‐solutions package 42 and by analyzing the electrical performance via the finite element method (FEM) 43 using the Lumerical DEVICE Charge package 42 .…”

It has been well documented that the usage of a textured cover layer reduces reflection from the air‐solar cell interface, which ultimately enhances the power conversion efficiency (PCE) of a solar cell. The most commonly used patterns, such as pyramids, micropillars, nanowires (NW), and nanoholes have been widely studied and optimized. Besides using such NWs to enhance light absorption, this work also additionally considers the concept of mimicking the antireflection coating of single or multiple layers in minimizing the reflectance and thus enhancing the total absorptance further. It is shown here that at least one order of magnitude shorter multilayer NW pattern of 268 nm total height can outperform a standard NW of 4270 nm height, which needs less material and can also be fabricated at a reduced cost. Furthermore, the proposed design with reduced height has a significantly lower surface‐to‐volume ratio, which also reduces surface recombination loss than the other textured surface patterns. The results presented in this work have been comprehensively analyzed by initially optimizing optical absorption and then completing the electrical simulations. The optimized design in conjunction with a back reflector offers an efficiency as high as 16.434%.

“…In addition to the SCAPS-1D simulator, modeling solar cell devices may also be done using other simulating programs such as AFORS-HET, TCAD, Silvaco ATLAS, and Lumerical. However, device optimization is not available in all sorts of solar cells in PV solar cells due to a few limitations and insufficient methods in physical models and parameters [56][57][58][59][60][61][62][63]. However, the main issue with the SCAPS-1D is the struggle to solve multi-dimensional issues, and it is also difficult to comprehend the findings in detail.…”

The simulated device structures of ITO/ZnO/Perovskite absorber layers (PAL)/Spiro-OMeTAD/Au with distinct absorbers were modeled and investigated using solar cell capacitance simulator (SCAPS-1D) simulating software (version 3.8). The primary objective is to enhance the thermal stability of the solar device. As the absorber thickness and temperature impact PV performance parameters, thus main aim of this work is to determine the optimum thickness of PAL as well as the temperature affectability on the PV performance of the cells. It was also observed that the maximum PV parameters (among the cells under consideration), viz. 29% PCE, are achieved with the formamidinium tin iodide (FASnI3) at the thickness of 600 nm. Similarly, the temperature of 300 K shows a much-improved efficiency offering nearly 29%. Further, the external quantum efficiency (EQE) and J-V also confirm the determent of the more stable, lead-free, FASnI3-based device, which can provide an effective way to develop highly efficient, low-cost solar cell devices.
