Special Issue Information

Organometal halide perovskites have attracted widespread interest in the research community thanks to their tunable optoelectronic properties. These semiconductors have found applications in solar cells, light-emitting diodes, and light detectors for visible light, as well as x-rays. In this Special Issue, we aim to collect experimental and review papers on the scaling up of the fabrication and on the large area characterization of perovskite-based devices. Particular focus will be given to the industrialization of the deposition of the perovskite layer itself, from ink formulation to fabrication via industrially viable techniques such as slot die, spray coating, ink-jet printing, blade coating, and thermal evaporation. Other relevant topics are the characterization and mapping of large-area samples that can be instrumental for inline metering during production and the patterning of the perovskite layer via laser patterning, digital printing, lithography or through novel methods. We welcome all papers that provide advancements towards the industrialization and automation of the production of perovskite-based devices by developing new deposition processes or new ink formulation that are industrially compatible.

Abstract
Long-term stability is one of the major challenges for p-i-n type perovskite solar modules (PSMs). Here, we demonstrate the fabrication of fully laser-patterned series interconnected p-i-n perovskite mini-modules, in which either single Cu or Ag layers are compared with Cu/Au metal-bilayer top electrodes.

Long-term stability is one of the major challenges for p-i-n type perovskite solar modules (PSMs). Here, we demonstrate the fabrication of fully laser-patterned series interconnected p-i-n perovskite mini-modules, in which either single Cu or Ag layers are compared with Cu/Au metal-bilayer top electrodes. According to the scanning electron microscopy measurements, we found that Cu or Ag top electrodes often exhibit flaking of the metal upon P3 (top contact removal) laser patterning. For Cu/Au bilayer top electrodes, metal flaking may cause intermittent short-circuits between interconnected sub-cells during operation, resulting in fluctuations in the maximum power point (MPP). Here, we demonstrate Cu/Au metal-bilayer-based PSMs with an efficiency of 18.9% on an active area of 2.2 cm2 under continuous 1-sun illumination. This work highlights the importance of optimizing the top-contact composition to tackle the operational stability of mini-modules, and could help to improve the feasibility of large-area module deployment for the commercialization of perovskite photovoltaics.

The upscaling of perovskite solar cells is one of the challenges that must be addressed to pave the way toward the commercial development of this technology. As for other thin-film photovoltaic technologies, upscaling requires the fabrication of modules composed of series-connected cells. In this work we demonstrate for the first time the interconnection of inverted modules with NiOx using a UV ns laser, obtaining a 10.2 cm2 minimodule with a 15.9% efficiency on the active area, the highest for a NiOx based perovskite module. We use optical microscopy, energy-dispersive X-ray spectroscopy, and transfer length measurement to optimize the interconnection. The results are implemented in a complete electrical simulation of the cell-to-module losses to evaluate the experimental results and to provide an outlook on further development of single junction and multijunction perovskite modules.
