“…Sputtering transparent conductive oxides, such as indium tin oxide (ITO), , zinc-doped tin oxide (ZTO), aluminum-doped zinc oxide (AZO), , or indium zinc oxide (IZO), as a top contact, has emerged as a promising approach that addresses most of the degradation processes. ITO evolved as one of the best solutions that address the majority of the instability issues.…”

The commercialization of perovskite solar cells (PSCs) requires the development of long-term, highly operational-stable devices. An efficient barrier layer plays a key role in improving the device stability of planar PSCs. Here, we focus on the use of sputtered indium tin oxide (ITO) as a barrier layer to stop major degradations. To mitigate efficiency losses of cells with the ITO barrier, we optimized various sputtering process parameters such as ITO layer thickness, target power density, and working pressure. The fabricated planar inverted PSCs based on the novel ITO barrier optimization demonstrate a power conversion efficiency (PCE) of 19.05% on a cell area of 0.09 cm 2 . The encapsulated cells retained >80% of their initial efficiency after 1400 h of continuous illumination at 55 °C and 94.5% of their initial PCE after 1500 h stored in air. Employing such a holistic stabilization approach, the PSC minimodules without encapsulation achieved an efficiency of 16.4% with a designated area of 2.28 cm 2 and retained approximately 80% of the initial performance after thermal stress at 85 °C for 350 h under ambient conditions.

“…Some inherently damage the underlying layers, as is the case for physical vapor deposition. [22] Others require temperatures exceeding the thermal budget of preceding layers, for example, 200 °C for silicon heterojunction (SHJ) solar cells. [23] The sequential layer deposition of conventional PSC fabrication implies critical constraints to the device architectures.…”

Perovskite/silicon tandem photovoltaics have attracted enormous attention in science and technology over recent years. In order to improve the performance and stability of the technology, new materials and processes need to be investigated. However, the established sequential layer deposition methods severely limit the choice of materials and accessible device architectures. In response, a novel lamination process that increases the degree of freedom in processing the top perovskite solar cell (PSC) is proposed. The very first prototypes of laminated monolithic perovskite/silicon tandem solar cells with stable power output efficiencies of up to 20.0% are presented. Moreover, laminated single‐junction PSCs are on par with standard sequential layer deposition processed devices in the same architecture. The numerous advantages of the lamination process are highlighted, in particular the opportunities to engineer the perovskite morphology, which leads to a reduction of non‐radiative recombination losses and and an enhancement in open‐circuit voltage (Voc). Laminated PSCs exhibit improved stability by retaining their initial efficiency after 1‐year aging and show good thermal stability under prolonged illumination at 80 °C. This lamination approach enables the research of new architectures for perovskite‐based photovoltaics and paves a new route for processing monolithic tandem solar cells even with a scalable lamination process.

“…These goals were developed with community input gathered through a recent request for information (RFI). 31 To accelerate achievement of these targets and tackle critical scale-up challenges, SETO has funded projects involving development of allperovskite tandem modules, 50 perovskite−silicon tandem modules, 51 and perovskite single-junction modules in both conventional 52 and bifacial 53 form factors.…”
