“…Their findings showed that the increase of the absorber layer thickness leads to the number of absorbed photons and the improvement of the performance of the bilayer solar cell. Prasad et al 31 performed a numerical simulation of a single absorber layer CuIn 0.69 Ga 0.31 Se 2 solar cell device and bilayer CuIn 0.69 Ga 0.31 Se 2 /CuIn 0.55 Ga 0.45 Se 2 solar cell under the illumination of AM 1.5 G.S. They simulated to study the influence on bilayer device (J–V) characteristics.…”

Numerical simulation of an all-perovskite bilayer solar cell has been conducted by the SCAPS-1D. The presented structure employs MAPbI3 as a relatively wide bandgap (1.55 eV) top absorber and FA0.5MA0.5Pb0.5Sn0.5I3 as a narrow bandgap (1.25 eV) bottom absorber. The viability of the proposed design is accomplished in two steps. First, to validate this study, two inverted solar cells in standalone conditions are simulated and calibrated to fit previously reported state-of-the-art results. Second, both these devices are appraised for the bilayer configuration to boost their performances. Affecting parameters such as the thickness of perovskite absorbers, the work function of front and rear contacts, and the effect of temperature have been studied because solar cells are temperature-sensitive devices, and also carrier concentration and their mobility get overwhelmingly influenced as temperature increases. It is manifested that using bilayer structures could easily widen the absorption spectrum to the near-infrared region and significantly enhance the performance of the device which is mainly affected by the thickness of the FA0.5MA0.5Pb0.5Sn0.5I3 layer. Also, it has been found that the work function of the front contact has a prominent role with its optimal values being above 5 eV. Finally, the optimized inverted all-perovskite bilayer solar cell delivers a power conversion efficiency of 24.83%, fill factor of 79.4%, open circuit voltage of 0.9 V, and short circuit current density of 34.76 mA/cm2 at 275 K and a thickness of 100 nm and 600 nm for MAPbI3 and FA0.5MA0.5Pb0.5Sn0.5I3, respectively.

“…The initial cell efficiency of 18.93% for a 2 μm active layer thickness has increased to 19.45% for an active layer reduced to 0.5 μm. We have recorded in Table similar results related to the optimization of the performance of other cells referenced in the scientific literature. − The results obtained confirm our hypothesis that the main cause of the efficiency loss, as a result of reducing the absorber coat depth, is the disruption of the charge-carrier transport. The decrease in photon absorption rate would be a secondary cause for active layer thicknesses of the order of 500 nm and above.…”

In this research article, we carry out investigation on compensating the efficiency loss in thin-film CIGS photovoltaic (PV) cell due to absorber coat depth reduction. We demonstrate that the efficiency loss is mainly caused by the disruption of the charge-carrier transport. We propose an architecture engineered with a stepped band gap profile for improving the efficiency of charge-carrier transport and collection. By modifying the gallium content, we tuned the band gap profile of the active layer of a reference experimental cell from which we previously collected all parameters. Using the simulator environment SCAPS-1D, we modeled a three-steps stacking profile of active layer with different gallium contents from one layer to another. Based on the results obtained, the band gap configuration herein proposed appears to be a prospective strategy for high-performance ultrathin Cu(In,Ga)Se2-based PV cell architecture engineering. By combining this approach with the optimization of the active layer doping, we enhanced the yields of the reference structure from 18.93% for a 2 μm active layer to 23.36% for only 0.5 μm thickness of active layer, that is, an enhancement of 4.4%. The fill factor increased from 73.24 to 81.73%, that is, an additional stability indicator value of 8.5%. The good values of the obtained efficiency and the improvement of the fill factor value are relevant indicators of a stable device. Active layer stacking combined with a stepped band gap profile and doping level optimization is definitely providing new perspectives in thin-film CIGS high-performance PV cell achievement.

In this study, an innovative solar cell utilizing antimony selenide (Sb2Se3) as a base material and incorporating a dual absorber layer is comprehensively examined using the Solar Cell Capacitance Simulator (SCAPS-1D) tool. The aim is to assess the performance of the solar cell with different absorber layers in combination with Sb2Se3. Results demonstrate that the solar cell employing an organic CH3NH3SnI3 absorber layer alongside Sb2Se3 achieves superior efficiency compared to one with an inorganic CZTS absorber layer. The two absorber layers investigated are the inorganic Copper Zinc Tin Sulfide (CZTS) and the organic methylammonium tin iodide (CH3NH3SnI3The dual absorber layer configuration proves advantageous by enhancing light absorption. The solar cell architecture comprises ZnO/i-ZnO/ Sb2Se3/CZTS or CH3NH3SnI3/NiO layers, resulting in an improved efficiency of up to 36.70%. Throughout the analysis, parameters such as concentration, band gap, thickness, and temperature are systematically adjusted to evaluate the behavior of this unique solar cell structure. The findings from the study indicate a noticeable enhancement in the performance of Sb2Se3 solar cells when employing the bilayer absorber structure comprising Sb2Se3 and CH3NH3SnI3.
