“…For example, photonic curing leads to large improvements in the time required to cure the perovskite layers even down to the ms-s range, 93,94 and has also been applied to the TiO 2 layers. 45,95 …”

To bring perovskite solar cells to the industrial world, performance must be maintained at the photovoltaic module scale. Here we present large-area manufacturing and processing options applicable to large-area cells and modules. Printing and coating techniques, such as blade coating, slot-die coating, spray coating, screen printing, inkjet printing, and gravure printing (as alternatives to spin coating), as well as vacuum or vapor based deposition and laser patterning techniques are being developed for an effective scale-up of the technology. The latter also enables the manufacture of solar modules on flexible substrates, an option beneficial for many applications and for roll-to-roll production.

“…Such reductive, light induced curing has recently been described by Secor et al, [64] and Costa Bassetto et al [65] where certain compounds, such as alcohols can act as the reducing agents, while the temperature in the irradiated materials can reach several hundred degrees. [66] Indeed, several works on flash lamp-based curing/reducing of graphene oxide films as a cost-and time-efficient process have been reported. [16,67,68]…”

Highly Loaded Mildly Edge‐Oxidized Graphene Nanosheet Dispersions for Large‐Scale Inkjet Printing of Electrochemical Sensors

et al. 2020

Inkjet printing of electrochemical sensors using a highly loaded mildly edge-oxidized graphene nanosheet (EOGN) ink is presented. An ink with 30 mg/mL EOGNs is formulated in a mixture of N-methyl pyrrolidone and propylene glycol with only 30 min of sonication. The absence of additives, such as polymeric stabilizers or surfactants, circumvents reduced electrochemical activity of coated particles and avoids harsh postprinting conditions for additive removal. A single light pulse from a xenon flash lamp dries the printed EGON film within a fraction of a second and creates a compact electrode surface.An accurate coverage with only 30.4 μg of EOGNs per printed layer and cm 2 is achieved. The EOGN films adhere well to flexible polyimide substrates in aqueous solution. Electrochemical measurements were performed using cyclic voltammetry and differential pulse voltammetry. An all inkjet-printed threeelectrode living bacterial cell detector is prepared with EOGN working and counter electrodes and silver-based quasi-reference electrode. The presence of E. coli in liquid samples is recorded with four electroactive metabolic activity indicators.

“…[51,52] An mp-TiO 2 ETL was deposited by spincoating the above-mentioned paste precursors on the c-TiO 2coated substrates with aspeed of 5000 rpm for 40 s. After that, the mp-TiO 2 ETL substrates were sintered at 450 8Cf or 30 min and sequentially cooled to room temperature. First, ac -TiO 2 layer was formed by spin-coating at itanium isopropoxide in acidic solution of isopropanol on the FTO substrates at 3000 rpm for 30 s, and then is was annealed at 500 8Cf or 30 min and naturally cooled to room temperature.…”

High quality electron-transport layer (ETL) with superior optical and electrical properties is an essential part in high efficient perovskite solar cells (PSCs). In this work, SiW -TiO mesoporous film is prepared by a facile one-step spin-coating deposition method and successfully applied as ETL in PSCs. Compared with pristine TiO -based PSC, the SiW -TiO -based one shows a remarkable enhanced power conversion efficiency (PCE) from 12.00 to 14.66 %, which is owed to the higher conductivity, electron-extraction efficiency, and well-matched energy level alignment of SiW -TiO film. Moreover, the SiW -TiO -based device also shows a good long-time stability in under ambient conditions. This work demonstrates that using polyoxometalates (POMs) to modify the metal-oxide semiconductors is an effective approach for further enhancing the performance of PSCs.
