“…In order to improve hole transport, FK209 -a cobalt based compound -was employed as Spiro-OMeTAD dopant 19 . The devices were sealed according to a previously published method 20 , to protect the cells from contamination and moisture, thus preventing cell degradation due to extrinsic factors. In this work we investigated the behavior of an "early failed" cell, to evaluate the phenomena leading to the cell breakdown.…”

Operational stability is the main issue hindering the commercialisation of perovskite solar cells. Here, a long term light soaking test was performed on large area hybrid halide perovskite solar cells to investigate the morphological and chemical changes associated with the degradation of photovoltaic performance occurring within the devices. Using Scanning Transmission Electron Microscopy (STEM) in conjunction with EDX analysis on device cross sections, we observe the formation of gold clusters in the perovskite active layer as well as in the TiO mesoporous layer, and a severe degradation of the perovskite due to iodine migration into the hole transporter. All these phenomena are associated with a drastic drop of all the photovoltaic parameters. The use of advanced electron microscopy techniques and data processing provides new insights on the degradation pathways, directly correlating the nanoscale structure and chemistry to the macroscopic properties of hybrid perovskite devices.

“…Those methods include common lab-scale techniques, such as spin-coating, and techniques that could be scalable to semi-industrial or industrial processes, such as spray-coating, screen printing, inkjet printing, slot-die coating, and blade-coating. [27][28][29][30] In this work, we present an investigation of three techniques, spin-coating (Figure 1a), blade-coating (Figure 1b), and spray-coating (Figure 1c), for the processing of the charge transport layers (electron transport layer (ETL) and hole transport layer (HTL)) and the active layer of perovskite solar cells using 5 cm × 5 cm sized substrates as basis. Figure 1d illustrates the structure of the devices (glass/FTO/ETL/Perovskite/HTL/Au), and Figure 1e shows the energy levels of the components.…”

Hybrid organic-inorganic perovskites have attracted interest in photovoltaic applications due to their excellent optoelectronic properties and low-temperature processability. From 2009 to 2021, lab-scale perovskite solar cells (PSC) reached a power conversion efficiency (PCE) of 25.7%, and a PCE of 17.9% for perovskite solar modules with an area of 800 cm2. Here, we present an investigation using three deposition techniques, spin-coating, blade-coating, and spraycoating, to process the charge transport layers and the active layer of perovskite solar cells onto 5 cm × 5 cm sized substrates, with device structure glass/fluorine-doped tin oxide (FTO)/c-TiO2/ meso-TiO2+Perovskite/2,2’,7,7’-tetrakis(N,N-di-p-methoxyphenyl-amine)9,9’-spirobifluorene (spiro-OMeTAD) or poly(3-hexylthiophene) (P3HT)/Au. Large-area PSC achieved an opencircuit voltage of around 1.1 V and PCE of 6%. The power generated was sufficient to start a fan. Furthermore, the connection in series of two large-area PSCs generated a voltage of 1.9 V. Then, we developed a simple method for manufacturing a monolithic perovskite mini-module containing two series-connected PSCs without using laser-scribing processes (usually named P1, P2, and P3 processes). This mini-module delivered a voltage of 1.52 V. Both voltages (1.9 and 1.52 V) were enough to turn on a red (or yellow) light-emitting diode (LED). To our knowledge, this is the first scientific report describing the assembly of a large-area n-i-p perovskite single cell and mini-module in Brazil.

“…Besides perovskite, interfaces rule the stability and efficiency of the device. , Many researchers improved perovskite stability by inserting graphene and related two-dimensional (2D) material-based interlayers to passivate perovskite, reducing recombination and increasing wettability, as in the case of MAPI and triple cation perovskite solar cells. − Scalability of this technology is fundamental to be exploited into the market: perovskite modules appeared in the literature in early 2014 and so far the scientific community has been trying to use alternative methods to replace the conventional spin-coating process used for small-area devices, ,− reaching a power conversion efficiency (PCE) of 18.13% in a 21 cm 2 active area …”

The use of solution processes to fabricate perovskite solar cells (PSCs) represents a winning strategy to reduce capital expenditure, increase the throughput, and allow for process flexibility needed to adapt PVs to new applications. However, the typical fabrication process for PSC development to date is performed in an inert atmosphere (nitrogen), usually in a glovebox, hampering the industrial scale-up. In this work, we demonstrate, for the first time, the use of double-cation perovskite (forsaking the unstable methylammonium (MA) cation) processed in ambient air by employing potassium-doped graphene oxide (GO-K) as an interlayer, between the mesoporous TiO2 and the perovskite layer and using infrared annealing (IRA). We upscaled the device active area from 0.09 to 16 cm2 by blade coating the perovskite layer, exhibiting power conversion efficiencies (PCEs) of 18.3 and 16.10% for 0.1 and 16 cm2 active area devices, respectively. We demonstrated how the efficiency and stability of MA-free-based perovskite deposition in air have been improved by employing GO-K and IRA.
