“…PEDOT:PSS (poly (3,4-ethylenedioxythiophene) polystyrene sulfonate) is a popular conductive polymer, used as a hole transport layer in organic photovoltaics (OPVs) and organic light emitting diodes (OLEDs) [1][2][3][4][5][6] given its high workfunction, reaching 5.2 eV, and high conductivity, reaching 130 S cm -1 in in-plane charge transport [7][8][9]. In all such applications, conduction takes place in the transverse, z, direction while the value of the workfunction of each conductive layer or active material is most important to maintain the continuous charge flow in the electron and hole transport, respectively.…”

“…A summary of inkjet printable inks and suppliers has been shown in Table 2. Additives also have a robust influence on morphology, printability, and optoelectronic characteristic of the PEDOT:PSS and functional layer [40,45]. The robustness of inkjet printing is the advanced digital patterning of subtle line and grid structures, which could be utilized as a part of OPV devices, particularly for front grid electrodes [46,47], in addition to back electrodes [42,43].…”

Abstract:In recent years, organic solar cells became more attractive due to their flexible power devices and the potential for low-cost manufacturing. Inkjet printing is a very potential manufacturing technique of organic solar cells because of its low material usage, flexibility, and large area formation. In this paper, we presented an overall review on the inkjet printing technology as well as advantages of inkjet-printing, comparison of inkjet printing with other printing technologies and its potential for organic solar cells (OSCs). Here we highlighted in more details about the viability of environment-friendly and cost-effective, non-halogenated indium tin oxide (ITO) free large scale roll to roll production of the OSC by inkjet printing technology. The challenges of inkjet printing like the viscosity limitations, nozzle clogging, coffee ring effect, and limitation of printability as well as dot spacing are also discussed. Lastly, some of the improvement strategies for getting the higher efficiency of the OSCs have been suggested.

“…Inkjet printing technique has been applied mainly for deposition of active layer [1][2][3][4][5][6][7][8][9] and buffer layer [10] in organic solar cells. For printing the active layer, besides the chemical properties of the active material, the solvent used plays a key role in determining the nature of droplets, film formation and the reliability of the printing process.…”

“…For example, the use of high boiling point solvent may require a post annealing treatment to transform the material from liquid to solid state and to produce high quality thin films morphology, hence high photovoltaic performance. Recently, there have been an intensive study on the performance of inkjet printed organic solar cells related to the regioregularity of polymer [1], the active material composition [2], the solvent system and drying process [3][4][5][6][7][8][9] on the devices.…”

One of critical factor in determining the performance of solar cells is the morphology of the active layer. The drying process of the active layer prepared by inkjet printing technique plays a key role in obtaining high quality surface morphology. This paper reports the effect of thermal annealing on the morphology of printed active layer. The printed active layer is a blend of poly(3-octylthiophene-2,5-diyl) and (6,6)-phenyl C 71 butyric acid methyl ester dissolved in a mixture of dichlorobenzene:mesitylene. The printed films were then annealed at three different temperatures, namely 120, 140, and 160• C for 60 min to obtain the best performance of solar cells. It was found that the performance of solar cells strongly depends on the annealing temperature. The devices with the active layer annealed at 140• C exhibits the highest performance with short circuit current density and open circuit voltage as high as 2.88 µA/cm 2 and 0.85 V, respectively. The effect of annealing on the properties of printed active layer will be discussed.
