Effect of the HTL Layer (a-Si) on the Efficiency of the CdS/CdTe Solar Cell via Numerical Simulation
In this study, we investigate the effect of incorporating a silicon layer on the performance of a base solar cell (ZnO/CdS/CdTe/Al), focusing on both its efficiency and current-voltage (J-V) characteristics, using the one-dimensional simulation tool AMPS-1D (Analysis of Microelectronic and Photonic Structures in One Dimension). We also analyzed how the thickness of the absorber layer (CdTe) influences the cell’s performance. The highest efficiency, 25.028%, was obtained for the simulated cell with an added amorphous silicon (a-Si) layer. In this configuration, the active CdTe layer had a thickness of 1000 nm, while the a-Si layer was 10 nm thick. The integration of the a-Si HTL layer enhances the overall efficiency of the cell by minimizing losses due to recombination at the CdTe/electrode interface. Furthermore, the results demonstrate that optimizing the thickness of the CdTe absorber is crucial for balancing light absorption and carrier collection, thereby maximizing device performance. These findings highlight the potential of combining CdTe absorbers with thin a Si layers as a promising pathway for improving next-generation thin-film solar cells, offering a cost effective and efficient alternative for photovoltaic applications.

Numerical Simulations for the Performance Optimization of SnO2/Cs2AgInBr6/CuO Lead Free Perovskite Solar Cells
This study presents a numerical investigation of the photovoltaic performance of a lead-free double Perovskite Solar Cell (PSC) based on Cs2AgInBr6 as the absorber layer. Using the one-dimensional solar cell simulation tool AMPS-1D, critical device parameters, including active layer thickness and acceptor doping density, were evaluated. The impact of these parameters was tested on performance indicators, such as current density-voltage (J-V) characteristics, Open-Circuit Voltage (OVC), short-circuit current density (JSC), fill factor (FF), and Power Conversion Efficiency (PCE). The results revealed that an optimal active layer thickness of 500 nm, combined with an acceptor density in the range of 1013-1015 cm-3, maximized the device performance. Under these conditions, the solar cell achieved a PCE of 24.96%, with JSC = 29.40 mA/cm2, VOC = 0.969 V, and FF = 87.6%. These values underscored the promising potential of Cs2AgInBr6 as a non-toxic, eco-friendly alternative to lead-based perovskites in photovoltaic applications.

Improving the performance of a SnO2/CuO/GaAs solar cell using numerical simulation
Advancing research on solar conversion systems is vital for maximizing the potential of this renewable energy source. Achieving this requires further exploration into the development of solar cells, which are integral to these technologies. In this study, we simulated a lead-free double perovskite solar cell made from copper oxide (CuO) using the one-dimensional AMPS-1D simulation tool. We examined how variables such as cell thickness, temperature, and rear metal contact impact solar cell performance. Our findings indicate that an active layer thickness of 900 nm (CuO) and a temperature of 300 K provide the best performance for the cell. After optimization, the solar cell achieves a short-circuit current (JSC) of 33.624 mA cm⁻², an open-circuit voltage (VOC) of 0.844 v, fill factor (FF) of 86.5% and conversion efficiency (Eff) of 24.564 %.

Comparative study of (CdS/CIGS) and (ZnSe/CIGS) heterojunction solar cells Using AMPS-1D software.
Abstract. In this paper, we presented a simulation study of Cu (In, Ga) Se2 (CIGS) photovoltaic cell, using the one-dimensional calculation code AMPS-1D (One Dimensional Analysis of Microelectronic and Photonic Structures). Two types of cells are simulated; each one with a different buffer layer: ZnSe or Cds. We have studied the effect of the thickness of : the absorber layers: CIGS (Cu (In, Ga) Se2), and the buffer layer (Cds or ZnSe). The current-voltage characteristic (J-V), the electrical parameters (Jsc; Eff; FF; Voc) and the external optical efficiency EQE (λ) are deduced. The bestperforming cell found was the simulated one with the ZnSe layer, where its absorber layer thickness was chosen: w=2 μm, given an efficiency of 23.366 %, with: JSC = 36.808 mA/cm2, FF = 0.842 and VOC = 0.754 V. The ZnSe buffer layer is a good alternative buffer layer to replace Cds, with a high-bandgap buffer layer to achieve better JSC, where the same stability is realized as traditional Cds buffer layer photovoltaic cells. Keywords: Simulation by AMPS-1D, CIGS PV Cell, ZnSe, Cds.

Grätzel cell optimized for floating photovoltaic stations by AMPS 1D
Floating solar photovoltaic (FSPV) stations offer a number of advantages over those installed on the ground especially in conserving the land. The optimization of Grätzel photovoltaic cells, which are less expensive than Silicon photovoltaic cells, has given efficiency more than 20% actually. Their use, in these floating stations, but covered with titanium dioxide TiO2, to protect them from oxidation and ultraviolet rays, has served to reduce the cost of FSPV installation, which will contribute to making them more useful and more competitive. An optimization study of Grätzel photovoltaic cell performances is carried out, and illustrated.

Abstract: A hetero junction solar cell of the HIT type based on silicon, crystalline silicon and amorphous silicon (a-Si:H(p)/c-si(i)/a-Si:H(n)) was simulated, using the one-dimensional computer code AMPS-1D (One Dimensional Analysis of Microelectronic and Photonic Structures). On the one hand, our objective is to determine the effect of the thickness of the active layer (c-Si), as well as the variation of the concentration of the donors (Nd) of this layer on the performances of the cell: the short-circuit current (JSC), the open-circuit voltage (VOC), the form factor (FF) and the efficiency (Eff), and on the other hand, to find all the structural parameters characterizing each constituent layer of the cell. The results obtained from the optimization are shown in the following figure. We have found that the best thickness for the active layer that gives good performances of the studied solar cell, lies between 100 and 300 micro. Besides, the best value of Nd that provides better output parameters in the range of 5.1015 – 1016cm-3. In our optimization which has been done depending of temperature and wavelength, we have gotten those values of Voc= 0.795 V, Jsc= 38.599 mA/cm2 and FF= 0.800 corresponding to an efficiency of Eff=27.472%.

A solar cell of p-i-n type, containing hydrogenated amorphous silicon (a-Si:H) is simulated using the unidimensional computer code AMPS-1D. The objective of the present contribution is to investigate the effect of the thickness of the active layer a-Si:H(i) and the variation of its density of states (DOS) on the performances of the solar cell, namely the current of short circuit (JSC), the tension of open circuit (VOC), the form factor (FF) and the efficiency (Eff). Also we aim to determine the structural parameters characterizing each layer constituting the cell. Our results show that the best thickness for the active layer that gives good performances of the studied solar cell lies between 300 and 600 nm. Besides, the best DOS that provides better output parameters of the solar cell is determined to be in the range 5.1015–1016 cm−3. After optimization, our findings give values of Voc = 1.193 V, Jsc = 13.145 mA cm−2, FF = 0.807 which corresponds to an efficiency of Eff = 12.655%. The optimization has been done as a function of temperature and wavelength.

Résumé : Aux cours de ces dernières années, des améliorations considérables concernant les performances des cellules solaires ont permis d’aboutir à des rendements de conversion photovoltaïque respectivement de 28 %[1] et de 26 % pour des cellules solaires à base d’arsenic de gallium et de silicium cristallin, sous la condition d’éclairement d'un soleil. Une cellule solaire hétérojonction [2] de type p-GaAs/i-GaAs/n-Sicri/i-GaAs/n-GaAs, à base de silicium cristallin (c-si) et de galium d’arsenic a été simulée, en utilisant le code de calcul unidimensionnel AMPS-1D (One Dimensional Analysis of Microelectronic and Photonic Structures) [3]. D'un côté, notre objectif était de déterminer l'effet de l'épaisseur de la couche active, ainsi que la variation de la concentration de donneurs (Nd) de cette couche, sur les performances de la cellule, à savoir, le courant de court-circuit (JSC), la tension de circuit ouvert (VOC), le facteur de forme (FF) et l'efficacité (Eff). D'un autre coté et de trouver l'ensemble des paramètres structurels caractérisant chaque couche constituant la cellule. Les résultats obtenues après optimisation sont: Jsc= 39.036mA/cm2; FF= 0.800 ; Voc= 0.889 et le rendement de conversion énergétique est Eff =27.756%. Mots Clés: Cellule solaire, c-Si, GaAs, AMPS-1D.
