“…Beyond the wavelength of 860 nm, the EQE spectrum is zero due to the fact that the photons with energies below the absorber band gap are not absorbed because of their low energy, thus passing through the cell instead of absorption. [ 35 ] Figure 12b also shows the integrated current density (∫ J sc ) derived from the EQE spectra. ∫ J sc of 28.57 mA cm −2 is calculated for the proposed perovskite FASnI 3 device, which is very close to the cell current obtained from the J – V measurement shown in Figure 12a.…”

In this work, the photovoltaic outputs of the lead-free FASnI 3 -based perovskite solar cells are discussed by using Solar Cell Capacitance Simulator in One Dimension. The device outputs estimated theoretically in this study are almost equal to the experimental results, thereby verifying accuracy of this simulation. To find the decent electron transport layer (ETL), herein, various ETLs are presented instead of C 60 /BCP in the experimental FASnI 3 -based perovskite solar cell (PSC). The designed FASnI 3 PSC utilizing niobium pentoxide (Nb 2 O 5 ) as an ETL with an appropriate band alignment and a low lattice mismatch at FASnI 3 /ETL interface provides better efficiency by decreasing recombination at front side. The performances of the proposed PSC are also measured by altering the thickness and doping of ETL and absorber, interface defects, and series and shunt resistances. Furthermore, this paper reports the calculation of recombination coefficients at absorber/ETL interface, depletion region, and quasi-neutral region. An improved efficiency of 22.24% is evaluated at optimized thicknesses of 100 nm for HTL, 500 nm for absorber, 50 nm for ETL, and 50

“…This can be attributed to a decrease in the barrier height for the majority charge carriers at the backcontact interface with increasing metal work function, thereby improving the performance of the device.

Perovskite solar cells (PSC) have emerged as a prominent research area in solar cell development owing to their high‐efficiency and low‐cost photovoltaic technology. However, the transport layers typically employed in PSCs are organic materials, which may lead to unstable performance. In this work, a PSC with an indium tin oxide/WS2/FASnI3/Cd0.5Zn0.5S/Al configuration is proposed, and the parameters are optimized using the solar cell capacitance simulator‐1D program. In the present study, the impact of the WS2 layer thickness, electron‐transport layer material selection, absorber layer parameters, and interfacial defect states on the performance of the proposed solar cell is investigated. The optimized structure yields a power conversion efficiency of 23.1%, which is comparable to that of state‐of‐the‐art PSCs. The combination of an inorganic hole‐transport layer of WS2 presented in this work offers a novel approach to the development of PSCs.
