“…This is due to the absorption of more photons by thicker upper subcell and less light is transmitted to the lower subcell. Thus, the overall current density of tandem cells decreases [20]. The same phenomenon happens when the upper subcell thickness is less than the optimized value; less absorption occurs in the upper subcell, which reduceses the overall tandem current density.…”

Multijunction or tandem solar cells can split the solar spectrum over several subcells with different bandgaps to transform the sunlight into electricity more effectively than single-junction solar cells. The monolithic tandem design of third generation silicon solar energy materials is auspicious for photovoltaics.In this paper, the Simulation-based studies of copper zinc tin sul de/Silicon (CZTS/Si) tandem cells based on CZTS as an upper subcell and silicon as a lower subcell absorber layer have been performed using SCAPS-1D. This study aims to evaluate the CZTS tandem cells' performance based on the fact that both subcells are simulated to produce the best e ciency recorded at its bandgap. The Simulation and optimization of the single junction CZTS and Si solar cells were initially performed to t the state-of-art records e ciency of 11.65% and 18.7%, respectively. Further, both the upper and lower cell has evaluated at different thicknesses for tandem con guration after validation. Also, to obtain the current matching condition for tandem structure, the upper subcell's performance is investigated at different thickness ranges from 0.1 µm -1 µm while keeping the lower subcell thickness at 80µm. Thus, at optimized upper absorber thickness of 0.191 µm and lower subcell 80 µm at transmitted spectrum the current matching condition obtained and gave an e ciency of 10.6% and 11.9%, respectively. The maximum e ciency of ~ 23 is obtained for tandem design with enhancing open circuit voltage 1.4 V.

“…However, the record efficiency of about 10% obtained for a single junction CZTS solar cell is still very low when compared to its theoretical efficiency of 28% [42]. The excellent When the thickness of the kesterite increases above 300 nm up to 500 nm, an increase of 0.01% for the PCE (Figure 8b), a decrease of 0.03% for the FF (Figure 8a), an increase of 0.04 mA/cm 2 for the J sc and an increase of 0.0001 Volts for the V oc can be observed.…”

“…For the analysis of the proposed solar cell, the operating temperature was varied from 250 K to 350 K. The transport layers are responsible for collection of the charge carriers towards the charge collective contact. The various materials exhibit variable behavior in temperature fluctuations because all vary in conductivity, specific heat and density [42]. The results of the effect of temperature on V oc , FF, J sc and PCE are represented in Figure 12.…”

In this paper, a n-i-p planar heterojunction simulation of Sn-based iodide perovskite solar cell (PSC) is proposed. The solar cell structure consists of a Fluorine-doped tin oxide (FTO) substrate on which titanium oxide (TiO2) is placed; this material will act as an electron transporting layer (ETL); then, we have the tin perovskite CH3NH3SnI3 (MASnI3) which is the absorber layer and next a copper zinc and tin sulfide (CZTS) that will have the function of a hole transporting layer (HTL). This material is used due to its simple synthesis process and band tuning, in addition to presenting good electrical properties and stability; it is also a low-cost and non-toxic inorganic material. Finally, gold (Au) is placed as a back contact. The lead-free perovskite solar cell was simulated using a Solar Cell Capacitance Simulator (SCAPS-1D). The simulations were performed under AM 1.5G light illumination and focused on getting the best efficiency of the solar cell proposed. The thickness of MASnI3 and CZTS, band gap of CZTS, operating temperature in the range between 250 K and 350 K, acceptor concentration and defect density of absorber layer were the parameters optimized in the solar cell device. The simulation results indicate that absorber thicknesses of 500 nm and 300 nm for CZTS are appropriate for the solar cell. Further, when optimum values of the acceptor density (NA) and defect density (Nt), 1016 cm−3 and 1014 cm−3, respectively, were used, the best electrical values were obtained: Jsc of 31.66 mA/cm2, Voc of 0.96 V, FF of 67% and PCE of 20.28%. Due to the enhanced performance parameters, the structure of the device could be used in applications for a solar energy harvesting system.

A solar photovoltaic cell that is efficient and produces more power while taking up less area by absorbing high‐light energy. To improve the efficiency of the photovoltaic cell (PV), recombination technique is used in the absorption layers of the solar cell. The existing recombination techniques developed by the absorbers have weak interconnectivity, which may leads to defects, and efficiency is reduced due to the high resistance in diffusion length. So, “GNI‐doped PbS and MoS2 with ligands‐based PV structure” is proposed to improve the interconnection between the layers of the Solar cell. Here, gallium nitride (GaN) and indium nitride (InN) act as anode and cathode in first and third layer, to get the better interconnection by interchanging oxide ions where the Gallium Indium nitrate used as semiconductor. To improve the durability, second layer is doped with Bi3+ with Fe3+, which has a rhombohedral perovskite structure. Molybdenum di‐Sulfide (MoS2) is used in the last layer to improve light absorption. To maintain surface passivation, transformer‐based PV module with an HFC Thermal sub cell is employed in which Hydro Ferron chloride combined with Nano graphene platelets is to avoid Potential Induced Degradation and transformers to eliminate the stray current. While implementing, with very low cost the power conversion efficiency of proposed design increased upto 17%.
