“…For a p–i–n NIR‐transparent PSCs, several buffer layers fabricated through different processing techniques have been successfully implemented. Solution‐processed layers such as ALD‐processed SnO 2 , [ 78,82,185–187 ] ZnO [ 57,168–170,195 ] and ITO nanoparticles [ 192 ] are some of the widely used buffer layers.

“…[ 319 ] Degradations induced by metal electrode have been intensively investigated. [ 187,196,209,397,398 ] The most common metal electrodes in PSCs such as Au, Ag, and Al suffer from corrosion due to halide migration in perovskite. [ 207,403 ] It is found that the iodine in the perovskite absorber migrates through the HTL and oxidizes the Ag electrode to form an insulating layer of AgI.…”

production have resulted in the reduction of production cost and has facilitated the growth of solar PV technology. [2-6] To make the PV technology more costcompetitive compared to other conventional sources of energy and to further fuel its rapid deployment, the levelized cost of electricity (LCOE) of a PV system needs to be reduced. In a PV system, apart from PV modules, other constituent components such as mounting unit, wiring, inverters, and battery storage constitute about 55% of the total cost. [7,8] These components are generally referred to as the balance of system (BOS). The BOS cost scales proportionally with the area of solar panel installation. An ideal way to reduce the LCOE is by increasing the efficiency of the PV modules. [8] The efficiency of well-established solar cell technologies (Figure 1) such as crystalline silicon (c-Si), gallium arsenide (GaAs) and copper indium gallium selenide (CIGS) are progressing toward the Shockley-Queisser (S-Q) limit, leaving limited room for further improvement in their performance. The thermalization and non-absorption losses incurred in these solar cells mainly restrict their spectral utilization and, consequently, their performance. However, the thermalization losses incurred in single-junction solar cells can be mitigated by combining a wide-bandgap cell with a lowbandgap cell in a multijunction solar cell design, which possesses the ability to achieve efficiencies that surpass the S-Q limit of single-junction solar cells. The practical implementation of multijunction solar cells (MJSCs) utilizing III-V materials have achieved great success in the past. [9] Under 1 sun illumination, LG Electronics and Sharp Corporation have demonstrated monolithic two-terminal MJSC devices using 2-junction (InGaP/GaAs) and 3-junction (InGaP/GaAs/InGaAs) absorber layers to attain power conversion efficiencies (PCEs) of 32.8% [10] and 37.8% [11] respectively. In 2013, Spectrolab utilized a direct bonding technique to grow a lattice-matched 5-junction monolithic MJSC device and demonstrated an efficiency of 38.8% under 1 sun illumination. [12] Very recently, NREL developed a 6-junction monolithic MJSC device to demonstrate a PCE of 39.2% under 1 sun illumination. [13] Despite achieving efficiencies beyond the S-Q limit of singlejunction solar cells, the deployment of III-V MJSCs is limited to space applications due to their high manufacturing cost coupled with slow and complicated fabrication procedures. [14] Metal halide perovskite solar cells (PSCs) have gained tremendous attention due to their high power conversion efficiencies (PCEs) and potential for low-cost manufacturing. Their wide and tunable bandgap makes perovskites an ideal candidate for tandem solar cells (TSCs) with well-established narrow bandgap photovoltaic technologies, such as crystalline silicon and Cu(In,Ga)Se 2 , to boost the PCEs beyond the Shockley-Queisser limit at affordable additional cost. Although perovskite-based TSCs have shown rapid progress over the past few years, they are far from reaching the...

“…13,14 Experimentally, power conversion efficiencies over 26% and 27% have been achieved for perovskite-silicon monolithic two-terminal and mechanically stacked four-terminal arrangements, respectively. [15][16][17] The two-terminal perovskite-silicon tandem cell has achieved greater attention due to extensive use in industries with the least number of processing steps, substrates, and interconnection requirements. 18 Some research groups have investigated both cells with planar front surfaces 19 and those with textured surfaces.…”
