“…[ 37 ] The recombination layer should be chosen such that the electrical losses especially the voltage loss should be minimum with the requirement of a suitable work function to collect the charge carriers generated. [ 38 ] Also, the absorption properties of the recombination layer should be poor so as to avoid unwanted absorption of light by the layer, which in turn hinders the amount of light entering the bottom cell. Considering the band alignment conditions, the present simulation study employs indium doped tin oxide (ITO) for the recombination layer, which is placed between the MAGeI 3 and the TMD cells.…”

The modeling tool, SCAPS 1D, is applied to simulate a monolithic 2-T and mechanically stacked 4-T tandem solar device architectures with methyl ammonium germanium iodide (MAGeI 3 ) perovskite as the active layer of the top cell and transition metal dichalcogenide as the active layer of the bottom cell. To establish the requirement of current density matching between the two subcells of the monolithic 2-T configuration, a recombination layer composed of indium doped tin oxide (ITO) is also introduced. The thickness of the MAGeI 3 , TMD, and ITO are optimized to 950, 340, and 100 nm to achieve the current matching condition. The 2-T device configuration is able to establish a high fill factor (FF) and power conversion efficiency (PCE) of 86.19% and 27.09% after optimizing the physical parameters of the layers. The 4-T mechanically stacked tandem architecture is also simulated using the SCAPS 1D tool and a maximum possible PCE of 35.11% is achieved after optimizing the physical parameters of the light captivating layers, viz. thickness, the number density of defects and dopants, and the operating conditions viz. temperature, parasitic resistances, and work function of the materials employed as rear contacts.

“…Neglected voltageloss should be achieved by an excellent interconnecting layer. some demands are need for the recombination layer (1) to reduce the electrical losses electron and holes are collected from the different transport layer by the work function of the recombination layers (2) without damage to the lower layer, recombination layer need to be manufactured at very low temperature (3) to induce the current loss [72], the absorption of bottom cells doesn't affect by the transmittance of recombination layer, so that recombination layer must have high transmittance. TMO is the excellent material which have demanded above properties (low sheet resistance, high transmittance, high conductivity).…”

The tandem Solar cell has high power conversion efficiency (PCE), so they are taken as the next step in photovoltaic evolution. The tandem solar cell also overcome the limitations of Single-junction solar cells by reducing thermalization losses and also reduce the fabrication cost. The fabrication of tandem solar cells is highly efficient after the origination of halide perovskite absorber material, this material will shape the future of tandem solar cells. Researchers have already shown that this material can convert light more efficiently than standalone sub cell. Today, researchers around the world are keeping the configuration of a tandem solar cell as their agenda. A Tandem solar cell is a stacking of multiple layers having different bandgaps with specific maximum absorption and width. We reviewed perovskite/silicon tandem solar cells with different sub-module configurations. Move forward, we discuss the tandem module technology, sub cell of a tandem can be wired in several ways two terminals 2T monolithic and mechanically stacked, a four-terminal 4T mechanically stacked, and three-terminal 3T monolithic stack devices. This review paper provides a side-by-side comparison of theoretical efficiencies of multijunction solar cells. The highest efficiency has been evaluated at 39.4% for a three-level structure.

“…8. By far, the optical transmission surpassed that of the actual devices and amounts to 64.3 % under the perovskite bandgap [61]. At last, a four-terminal tandem device described combining a graphene-contacted top wide bandgap (Eg=1.6 eV) perovskite solar cell and an amorphous/crystalline silicon bottom solar cell (Eg=1.12 eV).…”

Nowadays, with all their different forms, tandem cells are considered on top of the modern fields that many researchers try to explore all over the world. Both theoretical studies and applied technologies are struggling to realize the theoretical limit of the single-cell efficiency (~30%). Many kinds of tandem cells can be gathered together in different categories. Concerning the materials used, they are classified into organic, inorganic, and hybrid. But sometimes, they are classified, focusing on the connections used for sub-cellsstacked, optical splitting, or monolithic. Halide perovskite-based solar cells have acquired great significance in recent years. They gained a major interest because of their cheap and simple manufacturing as well as fast efficiency improvements. All these advantages have already met those of the industrially prevailing multi-crystalline silicon. Integration of perovskite absorber materials into multi-junction cells encourages researchers to exceed the limits of siliconbased technology and run after higher power transforming efficiencies. Layering many absorbers solar junctions stacked one above the other helped in the absorption process throughout the solar spectrum, hence, more energy could be obtained from sunlight. Two qualities caused perovskites to become the ideal candidates: First, the availability of adjusting the energy gap of perovskite materials to a great extent. Second, the capability to produce high open-circuit voltages from wide-bandgap absorbers. Perovskites could be used combined with or as an alternative for silicon (Si) in photovoltaic technologies. Those technologies were used practically and could be collected in architectures of hybrid tandems or layered in all multi-junction perovskite cells. In this review, many opportunities for perovskite multi-junction cells were tested in an attempt to find out new developments via inspecting possibilities.
