“…Carriers' flow through the junction is very high: this is a short-circuit situation. This result is in good agreement with those already obtained in other works, both with the radial junction [11] and with the planar junction [8]. The decrease in the photocurrent density J ph observed with the increase of the base radius R b is explained by the fact that when R b increases the n-p junction becomes more distant.…”

“…There are thus several configurations: we encounter parallelepiped or cubic configuration with the classic horizontal junction between the base and emitter assuming that the generated carriers move from the base to the emitter parallel to the illumination [2] [3] [4] and vertical junction for the purpose to reduce the path of the carriers to the junction to decrease recombination in the base of the cell [5] [6] [7]. Also, we can find in the literature cylindrical configurations with planar [8] [9] [10] and radial [11] [12] [13] [14] p-n junction as depicted in Figure 1 which is deeply investigated in this paper. Trabelsi et al [9] and Mbodji et al [8] carried out work on a cylindrical grain N + /P polycrystalline solar cell.…”

“…Simulation work has highlighted the advantage of the radial junction over a planar junction [14]. Sam et al [11] were able, through a 2D approach, to study the effect of the base radius, the thickness and the wavelength on the photocurrent density and the quantum efficiency of a radial junction solar cell. However their study doesn't give any information on the effect of the base radius on the other electrical parameters such as photovoltage, electric power, fill factor, shunt and series resistances.…”

In this paper, we investigate theoretically a radial n + /p silicon solar cell in steady state and monochromatic illumination. The purpose of this work is to analyze the effect of the cell base radius on its electrical parameters. The continuity equation in cylindrical coordinates is established and solved based on Bessel functions and boundaries conditions; this led us to the photovoltage and photocurrent density in the cell. The open circuit voltage and the short circuit current density are then deduced and analyzed considering the base radius. Based on J-V and P-V curves, series and shunt resistances, fill factor and maximum power point are derived and the conversion efficiency of the cell is deduced. We showed that short circuit current density, maximum power, conversion efficiency and shunt resistance decrease with increasing base radius contrary to the open circuit voltage, the fill factor and the series resistance.

In this paper, we modeled and simulated two tandem solar cell structures (a) and (b), in a two-terminal configuration based on inorganic and lead-free absorber materials. The structures are composed of sub-cells already studied in our previous work, where we simulated the impact of defect density and recombination rate at the interfaces, as well as that of the thicknesses of the charge transport and absorber layers, on the photovoltaic performance. We also studied the performance resulting from the use of different materials for the electron and hole transport layers. The two structures studied include a bottom cell based on the perovskite material CsSnI3 with a band gap energy of 1.3 eV and a thickness of 1.5 µm. The first structure has an upper sub-cell based on the CsSnGeI3 material with an energy of 1.5 eV, while the second has an upper sub-cell made of Cs2TiBr6 with a band gap energy of 1.6 eV. The theoretical model used to evaluate the photocurrent density, current-voltage characteristic, and photovoltaic parameters of the constituent sub-cells and the tandem device was described. Current matching analysis was performed to find the ideal combination of absorber thicknesses that allows the same current density to be shared. An efficiency of 29.8% was obtained with a short circuit current density Jsc = 19.92 mA/cm2, an open circuit potential Voc = 1.46 V and a form factor FF = 91.5% with the first structure (a), for a top absorber thickness of CsSnGeI3 of 190 nm, while an efficiency of 26.8% with Jsc = 16.74, Voc = 1.50 V and FF = 91.4% was obtained with the second structure (b), for a top absorber thickness of Cs2TiBr6 of 300 nm. The objective of this study is to develop efficient, low-cost, stable and non-toxic tandem devices based on lead-free and inorganic perovskite.
