Utilization of Tin Halide as an absorber in Perovskite solar cells is immensely recognized as a substitute of lead halide absorber because of lead material’s toxicity. Also, Tin halide based Perovskites possess a potential for higher quantum efficiency because of their enhanced light absorption capability due to the wide-ranging absorption spectrum in the visible region with a comparatively lower bandgap of 1.3 eV than lead-based Perovskites. In the present work, glass/ transparent conductive oxide (TCO)/ titanium dioxide (buffer)/ tin halide Perovskite (Absorber)/ cuprous thiocyanate (HTM)/ Metal back solar cell structure has been designed and simulated by SCAPS software which yields Power Conversion Efficiency (PCE) of 28.32% and Fill Factor (FF) of 85.17%. The effect of total defect density, thickness, Valance Band Effective Density of States (VBEDS) and Conduction Band Effective Density of States (CBEDS) for an absorber layer has been analyzed. It has been observed that VBEDS variation has achieved PCE and FF to a significant extent i.e. up to 32.47% PCE and 85.86% FF

“…Recently, thin film solar cells have been presented as competitors to the single crystal silicon solar cells due to their low cost and their rapid efficiency improvement [1]. However, thin film solar cells technology has some limitations like difficulty of absorbing longer wavelengths of the light spectrum due to their small thickness of the active layer [2], toxic materials involved and stability issues [3]. So, this technology still requires more research before they can be made commercially available.…”

In this paper, an analytical model of a proposed low-cost high efficiency NPN silicon-based solar cell structure is presented. The structure is based on using low cost heavily doped commercially available silicon wafers and proposed to be fabricated by the same steps as the conventional solar cells except an extra deep trench etch step. Moreover, the cell has been engineered to react to the UV spectrum, resulting in a greater conversion performance. The presented analytical model takes the electrical and optical characteristics into account. Thus, the influence of both physical and technological parameters on the structure performance could be easily examined. Consequently, the optimization of the structure performance becomes visible. To inspect the validity of the analytical model, a comparison of the main performance parameters resulting from the model results with TCAD simulations is carried out showing good agreement.

“…In the last few years, the single crystalline silicon solar cells were competed by the thin-film solar cells (TFSCs) due to the low cost of TFSCs and the rapid improvement in its efficiency [1]. However, TFSCs have some restrictions, such as their limited effectiveness in absorbing the long wavelengths of solar radiation spectrum due to the small thickness of its active layer [2]. Besides, most of TFSCs encounter toxic materials in their structures [3].…”

Recently, there is a rapid trend to incorporate low cost solar cells in photovoltaic technology. In this regard, low-cost high-doped Silicon wafers are beneficial; however, the high doping effects encountered in these wafers render their practical use in fabrication. The npn solar cell microstructure has been found to avoid this issue by the proper design of vertical generation and lateral collection of the light generated carriers. We report on the impact of the p + base doping concentration, up to 2×10 19 cm-3 , on the npn microstructure performance to find the most appropriate way for high efficiency. To optimize the structure, a series of design steps has been applied using our previously published analytical model. Before inspecting the high doped base effect, firstly, the n + emitter is optimized. Secondly, the impact of bulk recombination inside the p + base is introduced showing the range of optimum base width (Wp). Then, we investigate thoroughly the impact of base doping levels for different base widths to get the optimum Wp that satisfies maximum efficiency. The results show that for p + base doping concentration ranging from 5×10 17 cm-3 to 2×10 19 cm-3 , the npn microstructure efficiency decreases from 15.9% to 9%, respectively. Although the efficiency is degraded considerably for higher doping levels, the structure still achieves a competitive efficiency at higher doping levels, for which its cost is greatly reduced, in comparison with thin film solar cells. Moreover, using higher doping permits lesser wafer area which could be beneficial for large area solar cells design.
