“…Currently, III-V compound materials are considered ideal for MJ solar cells [7,8]. Relevant literature has demonstrated that MJ solar cells fabricated from III-V compound materials have achieved a conversion efficiency of up to 46% under high solar concentration [9,10]. GaInP, InGaAs, and Ge triple-junction(TJ) solar cells have been extensively researched due to their excellent bandgap alignment in the lattice matching system [10].…”

In this study, comprehensive simulation analyses of a typical triple-junction solar cell were conducted using Silvaco ATLAS. 1. Modeling and simulating a typical triple-junction solar cell under AM1.5 solar spectrum at 300K to characterize various performance parameters of the cell under 1 sun; 2. Analyzing the influence of the thickness of top and middle cell layers on the efficiency of the cell; 3. Investigating the impact of doping concentration errors in individual subcell on the overall cell power deviation; 4. Al0.9Ga0.1As substitutes AlInP as the top FSF layer; 5. Analysis of the internal radiation efficiency of the dual-junction cells on this solar cell as a function of concentration factor; 6. Assessing the influence of interface defects at different positions and densities on the efficiency of this solar cell. The results indicate that thestudy provides a reference for the optimization of MJ solar cells and analysis of internal physical phenomena.

“…Therefore, renewable energy, an alternative to fossil fuel-containing sources, offers a solution to overcome this energy need. In solar cells (SC), which are the most promising alternative among renewable energy sources, photon energy from the sun can be collected cheaply, efficiently, and simply 1 . Especially Cadmium Tellurium (CdTe) based solar cells have recently attracted attention in academic and industrial studies due to their ability to reach 22.1% efficiencies 2 , 3 , high thermal cell stability, low cost, and long-term stable photovoltaic performance 4 – 7 .…”

Photonic-based functional designs and integrations for advanced optoelectronic devices are regarded as promising candidates considering the enhancement of efficiency and tunability. With the aim to improve photovoltaic performance by increasing photon harvesting, the study presents the prominent findings of experimental and theoretical comparison of optical and electrical evaluation integrating a functionally designed one-dimension photonic crystal (1D-PC) into CdTe solar cells. Since transparency of the CdS/CdTe heterojunction based solar cell (SC) is reduced by a photonic band gap formed by (MgF2/MoO3)N 1D-PC; namely, re-harvesting is improved by increasing absorbance. The period number at resonance wavelength of 850 nm and photocurrent density ($${J}_{ph}$$ J ph ) have remarkable influence on the investigation. For four periods, the reflectance in the region of photonic band gap is sufficient for photon harvesting and saturation occurs. The photovoltaic performances are comparatively analysed for SCs with and without 1D-PC produced at optimal values. The open-circuit voltage does not change, besides, short-circuit current density and maximum-current density vary between 15.86–17.23 mA cm−2 and, 13.08–15.41 mA cm−2. Having integrated the 1D-PC into the structure, it is concluded that the FF and power conversion efficiency increase from 55.27 to 63.35% with an improvement of 15.91% and, from 8.26 to 10.47% with an improvement of 21.10%.

“…Among the multijunction solar cells, the III-V semiconductor compound-based solar cells are the commercially available cells with the highest reported efficiency [12,13] reaching 46% under high solar concentration [2,3]. In this regard, the InGaP alloy is a vital material for highefficiency solar cells as it absorbs the visible part of the solar spectrum [14][15][16]. Besides, the GaAs compound (1.42 eV) absorbs the Near-Infrared Region (NIR) of the spectrum.…”

In this work, an optimization of the InGaP/GaAs dual-junction (DJ) solar cell performance is presented. Firstly, a design for the DJ solar cell based on the GaAs tunnel diode is provided. Secondly, the used device simulator is calibrated with recent experimental results of an InGaP/GaAs DJ solar cell. After that, the optimization of the DJ solar cell performance is carried out for two different materials of the top window layer, AlGaAs and AlGaInP. For AlGaAs, the optimization is carried out for the following: aluminum (Al) mole fraction, top window thickness, top base thickness, and bottom BSF doping and thickness. The electrical performance parameters of the optimized cell are extracted: J SC = 18.23 mA / c m 2 , V OC = 2.33 V , FF = 86.42 % , and the conversion efficiency ( η c ) equals 36.71%. By using AlGaInP as a top cell window, the electrical performance parameters for the optimized cell are J SC = 19.84 mA / c m 2 , V OC = 2.32 V , FF = 83.9 % , and η c = 38.53 % . So, AlGaInP is found to be the optimum material for the InGaP/GaAs DJ cell top window layer as it gives 4% higher conversion efficiency under 1 sun of the standard AM1.5G solar spectrum at 300 K in comparison with recent literature results. All optimization steps and simulation results are carried out using the SLVACO TCAD tool.
