“…Electron transport layer (ETL). Before Tin oxide deposition, each substrate was treated for 10 min in Uv-Ozone lamp to improve wettability of aqueous solution, then a colloidal solution of tin oxide diluted in water 2% v/v (from 15% colloidal solution Alfa Aesar) was deposited by slot-die coating technique in ambient air according to [14].Then the film was annealed in air at 150°C for 30 min to obtain about 40 nm thick SnO2. Perovskite and passivating layer.…”

Ltd; CsI, FAI and MABr from Great Cell Solar) was deposited by hybrid blade/slot-die coating (ambient air, 30% RH) double step technique (first step for PVSK precursor and second step for isopropanol antisolvent quenching) assisted by a heated airflow [15]. Then, 5 mM Phenethyl ammonium iodide (Dyenamo) solution in IPA was slot-die coated according to [14]. Hole transport layer (HTL) and top electrode.…”

“…Hole transport layer (HTL) and top electrode. The HTM Spiro-OMeTAD solution (60 mM, Sigma Aldrich) in chlorobenzene (the molar ratio between the dopants and the Spiro-OMeTAD is 0.5, 3.3 for lithium bis(trifluoromethanesulfonyl)imide and 4-tert-butylpyridine, respectively) was coated by an air assisted slot-die method in ambient [14]. For the ST perovskite solar modules, buffer layer deposition (molybdenum oxide, MoOx, or gold, Au) were thermally evaporated on top of the HTL.…”

<p>Perovskite technology has been advancing at unprecedented levels in the last years, with efficiencies reaching up to 25.7%. State of art results are obtained on a very small area scale (<0.1cm2), by adopting high materials wasting processes not compatible with industry and with market exploitation. Silicon is a well-established technology and one of the advantages of Perovskite is its ability to pair with Silicon forming a tandem device that extracts charges reducing transmission and thermalization losses. In this work, we focus on finding a strategy to fabricate 15.2x15.2 cm2 Perovskite modules by avoiding any spin coating deposition and by adopting a green solvent cleaning step. Furthermore, we optimize the ITO top electrode deposition by adjusting sputtering process and buffer layer deposition; finally, we focused on light management by applying an antireflective coating. We obtained a semi-transparent and a tandem Silicon-Perovskite module in 4T configuration on 225cm2 (4T configuration) with 13.18% and 20.99% efficiency, respectively, passing ISOS-L1 (under continuous light soaking in air) test with a remarkable T80 of 1459h </p>

Perovskite technology has been advancing at unprecedented levels over the past years, with efficiencies reaching up to 26.1%. State-of-the-art results are obtained on a very small area scale (<0.1 cm 2 ), by adopting high materials wasting processes not compatible with industry and with market exploitation. Silicon is a well-established technology and one of the advantages of perovskite is its ability to pair with silicon forming a tandem device that extracts charges reducing transmission and thermalization losses. In this work, we focused on finding a strategy to fabricate 15.2 × 15.2 cm 2 perovskite modules by using blade/slot-die coating and avoiding any spin coating deposition. Furthermore, we optimized the indium tin oxide top electrode deposition by adjusting the sputtering process and buffer layer deposition; finally, we focused on light management by applying an antireflective coating. We obtained a semitransparent and a tandem silicon-perovskite module in a four-terminal (4T) configuration over 225 cm 2 (4T configuration) with 13.18% and 20.91% efficiency, respectively, passing International Summit on Organic PV Stability ISOS-L1 (under continuous light soaking in the air) test with a remarkable T 80 of 1459 h.
