A multijunction or tandem technique comprising a wide bandgap top cell and a narrow bandgap bottom cell may be a major stepping stone in an attempt to obtain high-efficiency solar cells. However, easier said than done, it takes a lot to correctly optimize the structure of all the involved layers so as to possibly obtain the desired results. In this paper, a perovskite (CH 3 NH 3 PbI 3 )/FeSi 2 (p-i-n structure) 2-terminal (2-T) monolithic tandem solar cell is proposed and investigated using AFORS-HET v2.5 1D simulator. A hydrogenated amorphous silicon (a-Si:H)/hydrogenated microcrystalline silicon oxide (µc-Si 1−x O x :H) tunnel recombination junction is employed to interconnect both perovskite and FeSi 2 solar cell for current matching. The influence of both top and bottom absorber layer thickness is analyzed to optimize the device performance. The study reveals an optimized 26.3% efficient perovskite/FeSi 2 monolithic tandem solar cell with J SC (21.4 mA cm −2 ), V OC (1.63 V), and FF (74.86%). The results in this paper suggest FeSi 2 material with 0.87 eV bandgap as an alternative for narrow bandgap bottom cell for the perovskite-based tandem solar cells so as to obtain much higher efficiencies.

“…[4,5]. Adjoining two individual solar cells, however, can make the efficiency go beyond the single-junction solar cell limit of 33% [S-Q] [6][7][8][9]. De Vos [10] explained that the efficiency achieved by two or more adjoined solar cells can be greater than 40%.…”

“…Conventionally, the tunnel recombination junction (TRJ) layer is used to achieve the current matching between the top and bottom subcells of a tandem device. [ 7,12,52 ] In contrast, we used interlayer of ITO (10 nm) material as a common electrode between subcells to provide current matching. Appropriate lumped resistance (10 16 Ω) is added to the common electrode to prevent the flow of current in the added electrode and to force the current to flow from anode to cathode.…”

“…[ 6 ] It is worth noting that tandem devices designed using thin‐film Si have shown the potential of higher conversion efficiency and overcome the downsides mentioned earlier for the single‐junction PV devices such as transmission and thermalization losses. [ 7 ] Furthermore, to increase the efficiency of the tandem devices, different absorber materials have been used for the effective utilization of both lower and higher wavelength photons. Primarily, TSC is the combination of different single‐junction devices that responds to higher efficiencies with minimum thermalization/transmission losses by stacking different wide/narrow bandgap absorber materials.…”

Tandem solar cells (TSC) is the most promising photovoltaic technology, as it efficiently overcomes the thermalization and nonabsorption losses. In this context, thin-film/colloidal quantum dot (CQD)-based 2-terminal monolithic TSCs are designed using a-Si:H of wide bandgap (1.7 eV) as the top cell and PbS CQD of narrow bandgap (1.2 eV) as the bottom cell. Initially, top and bottom subcells are designed and calibrated to have state-of-the-art power conversion efficiencies (PCE) of 6.86% and 9.38%, respectively. Afterward, the thicknesses of the inverted bottom cell are optimized as 200 nm so as to obtain 8.34% efficiency. The standalone condition reflects current density (J SC)/open-circuit voltage (V OC) of 9.97 mA cm À2 and 0.91 V in the top cell and 21.28 mA cm À2 / 0.63 V in the bottom cell. Further, both subcells are evaluated for tandem configuration with ITO-based interlayer to provide the current matching conditions. In the proposed tandem design, the thickness of the absorber layers is optimized to achieve the highest J SC , which is indeed limited by the top cell, due to a lower J SC value of 10.61 mA cm À2 in standalone conditions. Optimized tandem design with 200 nm/150 nm-thick absorber layer-based top/bottom subcell results in

Nanocarbon materials, such as graphene and carbon nanotubes (CNTs), have attracted considerable attention as the main or supplementary components in various optoelectronics boosting the device performance and improving the process conditions. Specifically, their application to perovskite solar cells, which are among the most promising photovoltaic devices acknowledged for eco‐friendly energy generation, has significantly impacted the current standing of metal halide perovskite‐based devices. The uniqueness of the nanocarbon applications can be attributed to their outstanding optical, electrical, chemical and mechanical properties, which conventional materials do not possess. This review overviews past and present reports on graphene‐ and CNT‐incorporated perovskite solar cells. Versatile roles and various synthetic methodologies of the applied nanocarbons in perovskite solar cells, including the material growth methods and sources, and functions as transparent electrodes, charge‐transporting layers, interfacial layers, additives and encapsulants, are categorized and graphically illustrated. The discussion expands from single‐junction to tandem applications with silicon solar cells, where the nanocarbon materials also play an equally important yet divergent function. Applications of each graphene and CNTs to the silicon‐perovskite tandem solar cells are interpreted in terms of what roles they play and how they solve the conventional problems. This review serves as the guideline for the photovoltaics researchers in advancing devices using nanocarbons.
