Photovoltaic systems have reached impressive efficiencies, with records in the range of 20–30% for single-junction cells based on many different materials, yet the fundamental Shockley-Queisser efficiency limit of 34% is still out of reach. Improved photonic design can help approach the efficiency limit by eliminating losses from incomplete absorption or nonradiative recombination. This Perspective reviews nanopatterning methods and metasurfaces for increased light incoupling and light trapping in light absorbers and describes nanophotonics opportunities to reduce carrier recombination and utilize spectral conversion. Beyond the state-of-the-art single junction cells, photonic design plays a crucial role in the next generation of photovoltaics, including tandem and self-adaptive solar cells, and to extend the applicability of solar cells in many different ways. We address the exciting research opportunities and challenges in photonic design principles and fabrication that will accelerate the massive upscaling and (invisible) integration of photovoltaics into every available surface.

“…CIGS-based solar cells can be an alternative hybrid tandem partner to c-Si solar cells in light of its comparable efficiency (23.4%) and an ideal bandgap of 1.1 eV by compositional engineering for current matching. [5,153,154] CIGS is a direct-bandgap p-type semiconductor and absorbs most of the sunlight at a thickness of ≈1 µm because of its high absorption coefficient (≈10 5 in the visible range). [155] Thus, a much thinner absorber layer (1-4 µm) is implemented in the CIGS solar cell technologies compared to the c-Si solar cells, which lowers manufacturing cost, but CIGS raw materials are less abundant.…”

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...

“… 5 Furthermore, as the semiconductor band gap of a perovskite can be modified by adjusting the composition of the material, 6 many believe that they will find near-term practical application in silicon-perovskite tandem devices that have efficiencies surpassing those of current single-junction silicon-based devices. 7 …”

Over the past six years, researchers have investigated the use of spray coating to fabricate perovskite solar cells (PSCs), with the aim of demonstrating its viability as an industrial manufacturing process. This spotlight on applications outlines the key benefits of this coating technology and summarizes progress made to date, with attention focused on varied efforts to control the crystallization and uniformity of the perovskite layer. The emerging understanding of processes required to create smooth, dense spray-cast perovskite films has recently led to the demonstration of fully spray-cast PSCs with a power conversion efficiency of 19.4%.
