“…[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. [19] In single junction OPV device based on a conventional architecture, the active layer is deposited onto a hole-transporting layer.…”

“…This often results in no uniform phase segregation due to large fullerene / polymer rich grains in the cast films, reveals limiting the device performance 32 This critical issue was solved by adding the more suitable additive with solvent and it enhances the fullerene solubility and exhibit enhanced device performance. 13,[34][35][36][37][38][39][40][41][42][43] Therefore, development of polymer solar cell using chlorine-free solvents by spray coating is capable of delivering large-area, uniform films with small amounts of material, which is having the compatibility for roll-to-roll fabrication is crucial. 24,27 However, spray-coating techniques are being explored for large-area, uniform thin film and wastage of material is low compare with other method.…”

The PTB7:PC 71 BM polymer based solar cells have been successfully fabricated by spin and spray coating technique using chlorine-free solvent (xylene), which are desirable to reduce environmental issues. The surface morphology of fabricated film characterized by AFM reveals that the surface morphology of the film is uniform and smooth when xylene is used as compared with chlorobenzene. The highest power conversion efficiency (PCE) (5.07±.6) was achieved using spray-coating technique than that of spin coating technique (PCE of 4.47±.6). The enhancement in the performance of the polymer solar cell could be attributed to the improved charge carrier transportation due to additive. The combination of chlorine-free solvent and spraycoating method minimize the waste material and reduce the environmental problem in large-area production of organic solar cells (OSCs). and without DIO. From this Table 2, the OTFSC prepared in xylene with 3% DIO exhibits higher PCE =5.07% than without DIO (PCE =2.90%). This implies that the addition of DIO in active layer reveals increase in the J sc =12.07 mA/cm 2 , FF=56 %, R sh =398 Ω cm 2 and decreases the R s =5.5 Ω cm 2 , as a result of drastic improvement in the PCE =5.07% than without DIO, PCE=2.90%. Figure 5. J-V characteristics of PTB7:PC 71 BM based OSC devices with and without DIO using spray coating method.The AFM studies reveals that the pristine xylene exhibits larger surface aggregates due to improper mixing between donor and acceptor, which will diminish exciton migration and is not

“…These exceptional properties have attracted many researchers to utilize the PCDTBT thin film as an active layer in organic photovoltaic devices [10,12,13]. However, to the authors' best knowledge, no studies are available in the literature on modification of PCDTBT thin films into nanostructures.…”

Controlling the morphological, structural, and optical properties of one-dimensional PCDTBT nanotubes by template wetting

In this study, the synthesis of poly [N-9′-heptadecanyl-2, 7-carbazole-alt-5, 5-(4′, 7′-di-2-thienyl-2′, 1′, 3′-benzothiadiazole)] (PCDTBT) nanotubes via a templating method is reported. PCDTBT nanotubes were successfully grown by immersing the porous alumina template into 15 mg/ml of solution concentration for 2- and 24-h periods and annealed at 50°C. Changes in morphological and optical properties between nanotubes of different infiltration times (2 and 24 h) as well as its thin films are observed. The longer infiltration time of 24 h produced nanotubes with enhanced morphological, structural, and optical properties. Nanotubes that are formed between 2 and 24 h of infiltration show enhancement in absorption, photoluminescence, and shift in Raman peak if compared to their thin films.
