“…[17][18][19] For example, OPVs based on a blend of poly(3-hexylthiophene-2,5-diyl) (P3HT) and phenyl-C61-butyric acid methyl ester (PC 61 BM) were fabricated using an airbrush spray coating technique and had a PCE of 4.1%; a value typical of spin-cast OPVs based on this photoactive layer. [20] Spray-coating has also been used to fabricate OPV devices using a series of different carbazole/benzothiadiazole based polymerfullerene blends, with spin-and spray-coated devices having comparable efficiency. [19] Such progress has motivated us to explore the extent to which we can scale-up the spraycoating of OPV devices; a necessary step in the pathway by which any technology makes a -3 -transition from laboratory to factory.…”

We present bulk heterojunction organic solar cells fabricated by spray‐casting both the PEDOT:PSS hole‐transport layer (HTL) and active PBDTTT‐EFT:PC71BM layers in air. Devices were fabricated in a (6 × 6) array across a large‐area substrate (25 cm2) with each pixel having an active area of 6.45 mm2. We show that the film uniformity and operational homogeneity of the devices are excellent. The champion device with spray cast active layer on spin cast PEDOT:PSS had an power conversion efficiency (PCE) of 8.75%, and the best device with spray cast active layer and PEDOT:PSS had a PCE of 8.06%. The impacts of air and light exposure of the active layer on device performance are investigated and found to be detrimental. Copyright © 2015 John Wiley & Sons, Ltd.

“…These materials are seen as being a prototypical OPV system, but are limited by relatively low PCE. [16] More recent work has however explored spray-cast blends of amorphous donor-acceptor co-polymers with fullerene-derivative electron acceptors, with improved device performance demonstrated. [11,13,17,18] Spray-coating has also been used to deposit the various charge transporting layers used in OPV devices.…”

“…There are a number of publications on spray coating of photovoltaic inks (Green et al, 2008;Hoth et al, 2009;Ishikawa et al, 2004;Steirer et al, 2009;Vak et al, 2007;Park et al, 2011;Susanna et al, 2011;Girotto et al, 2011). This deposition method is very efficient especially for low viscosity solutions and is less demanding in terms of ink formulation.…”
