“…Since the texture not only is crucial to enhance light trapping but also has a high impact on the surface defect density, electrical properties of the c‐Si wafers, such as the lifetime of the minority charge carriers, are influenced as well. It was shown previously that a reduced pyramid size still results in excellent passivation and minority carrier lifetimes 4,5 …”

“…It was shown previously that a reduced pyramid size still results in excellent passivation and minority carrier lifetimes. 4,5 To allow the wet processing of the perovskite absorber, which normally has a thickness of 0.5-1 μm, the pyramid height must be well below 1 μm to prevent the generation of local defects or shunts in the top cell. 1,4 Different methods can be used for the deposition of the perovskite film, such as blade-or slot-die coating, physical vapor deposition, or spin coating.…”

Nano‐textured surfaces are an intriguing approach for optimizing the optical characteristics for monolithic perovskite/silicon tandem solar cells. Here, the development of different textures of silicon surfaces using various commercial additives is presented and their performance in silicon heterojunction (SHJ) and SHJ–perovskite tandem solar cells is discussed. After optical and electrical characterization, we show that nano‐textured surfaces can easily compete with standard textured surfaces, yielding higher average efficiencies in single junctions. In addition, their compatibility with solution‐processed perovskite top cells is demonstrated, yielding a perovskite/silicon tandem solar cell efficiency of >28% on a bottom cell with nano‐texture on both sides.

“…In this case, a perovskite layer with a thickness greater than the pyramid height need not be conformal and it can be deposited from solution. There is precedence for this approach: Ju et al and Nguyen et al have reported a silicon texturing process with pyramids smaller than 2 mm, 39,40 and several scalable solution-processing approaches that have been reported for single-junction perovskite solar cells 41 -including blade coating, 42,43 slot die coating, 44,45 and spray coating, 46,47 -may conceivably be adapted to this tandem application.…”

A new monolithic perovskite/silicon tandem solar cell architecture is proposed based on double-side-textured silicon cells with sub-micrometer pyramids. These pyramids are rough enough to scatter light within silicon nearly as efficiently as large pyramids but smooth enough to solution process a perovskite film. A bladecoated perovskite film planarizes the textured silicon cell. With a textured lightscattering layer added to the top to reduce front-surface reflectance, a monolithic perovskite/silicon tandem cell reaches an efficiency of 26%.

“…The chemical solution process used for sub‐micrometer texturing is well compatible with the Si manufacturing process, and the cost of textured surface cleaning is low. [ 168 ] Moreover, surface texturing of the perovskite layer is expected to further improve light trapping efficiency, [ 136 ] although the corresponding technology has not yet been fully developed. Thus, the combination of sub‐micrometer texturing with the use of solution‐processed perovskite films should allow one to meet the demand for high‐efficiency and cost‐effective hybrid tandems.…”

larger acceptance owing to their decreasing cost. However, Si cells feature power conversion efficiencies (PCEs) close to the maximum practically achievable value (29.4% for crystalline Si solar cells), which makes it difficult to further reduce the levelized cost of electricity by decreasing the power output-to-cost ratio. [7,8] The most straightforward solution to this problem is to hybridize multiple semiconductor layers in a tandem architecture for absorbing the different wavelengths of the solar spectrum using different solar cell technologies. [9-12] As proven by a theoretical tandem cell efficiency of ≈46%, [13] Si solar cells with a bandgap of 1.1 eV have been regarded as potential bottom subcells of hybrid tandems, additionally offering the benefits of mass production suitability owing to well-organized production lines and global supply chains. [13,14] However, Sibased hybrid tandem solar cells configured with cost-effective solar cell technologies, including dye-sensitized solar cell (DSSC) and organic photovoltaics (OPV), have far lower efficiencies than single-junction Si solar cells, predominantly because of the insufficient compatibility of the employed materials with Si solar cells. [15-19] Metal halide perovskite-based solar cells have attracted significant attention in recent years because of their potential to be processed at low cost, high efficiencies, excellent optoelectronic properties, and tunable bandgap. They have therefore considered as prospective components of hybrid tandems. [20] Previous studies on the fundamental working principle of the hydrogenated amorphous Si (a-Si:H)/a-Si:H tandem and related validation by empirical investigations show the feasibility of combining different solar cell technologies, [6,21-23] as exemplified by the pairing of high-bandgap perovskite subcells with low-bandgap Si subcells or the assembly of dual perovskitebased tandem solar cells exploiting perovskite bandgap tunability. [14,24-26] To date, considerable effort has been directed at the development of wide-bandgap perovskite solar cells (PSCs) (1.65-1.8 eV) for hybrid tandem applications, [27,28] and remarkable progress (i.e., a high open-circuit voltage (V oc) of 1.31 V with a wide bandgap of 1.72 eV (>90% of the Shockley-Queisser limit)) has been achieved. [29] Currently, researchers aim to realize perovskite-based hybrid tandem solar cells with PCEs of 30%. Nonetheless, considerable electrical property and fabrication process adjustments are required to integrate singlejunction perovskites into the hybrid tandem architecture. The introduction of an intermediate layer to bridge different solar Hybrid tandem solar cells offer the benefits of low cost and full solar spectrum utilization. Among the hybrid tandem structures explored to date, the most popular ones have four (simple stacking design) or two (terminal/tunneling layer addition design) terminal electrodes. Although the latter design is more cost-effective than the former, its widespread application is hindered by the difficulty of preparing...
