“…It was developed at the end of the 1990s from the necessity to deposit soft organic thin films (unicomponent layers or blends) preserving the properties of the used raw materials. MAPLE is also useful in the deposition of the polymers when the use of VTE results in the broken of the molecular chains [47,48]. It is also used for the deposition of thin films from small molecule compounds or oligomers [49,50].…”

“…In order to avoid the deterioration of the organic materials during the deposition were used lower laser fluences (<500 mJ/cm 2 ) compared to those used in the classical PLD [47] and targets (frozen in liquid nitrogen) formed from a mixture between the organic material and an adequate solvent used as a matrix [47,48]. The solvent is chosen in order to obtain homogeneous mixture with the organic material and to be compatible with the laser wavelength.…”

“…The solvent evaporation takes place at the absorption of the laser energy that is converted in thermal energy. Further, the solvent is pumped outside from the deposition chamber by the vacuum system [48]. The material of interest reaches the support where the nucleation process starts and the thin layer is formed.…”

Multilayer or blend heterostructures based on porphyrins and phthalocyanines were obtained on different substrates using VTE and MAPLE methods. Stacked structures based on ZnPc and C60 with NTCDA were prepared by VTE on ITO/glass, their current value being increased by the deposition of the materials in an inverted configuration or by using ITO/PEDOT:PSS as a substrate. Multilayer structures comprising ZnPc and NTCDA were fabricated by MAPLE on an AZO/glass. Treating the AZO in oxygen plasma, a higher current value was obtained for the deposited heterostructures. The oxygen plasma treatment can increase the work function of the AZO resulting in a decrease of the energetic barrier from AZO/organic interface and finally improving the charge transport. Stacked layers or blend heterostructures having ZnPc, MgPc and TPyP were deposited by MAPLE on ITO/PET. In the case of those containing MgPc and TPyP, an increase in the current value (in dark) was obtained for the blend compared to the stacked layer configuration. For those with ZnPc and TPyP, under illumination, a photovoltaic effect was observed for the blend structure. All heterostructures are featured by a large absorption in the visible domain of the solar spectrum and suitable electrical properties for their use in OPV applications.

“…MAPLE has the advantage that it can process soft materials (organics) that could not be transferred by other techniques because there is the risk that takes place-a decomposition of the materials. In MAPLE, the target is formed from the materials (one or more) that must be deposited, and an adequate solvent is used as matrix [43,44]. The solvent is chosen to obtain a homogeneous mixture (concentration usually below 3%) and to be compatible with the used laser wavelength.…”

“…In MAPLE, smaller fluence are used (under 0.5 J/cm 2 ) in order to prevent the deterioration of the materials [44]. Another great advantage compared with methods used for the deposition of the organic materials is the possibility to obtain stacked layers without deterioration of the preliminary deposited layer [31].…”

Laser techniques such as pulsed laser deposition, combinatorial pulsed laser deposition, and matrix-assisted pulsed laser evaporation were used to deposit thin films for optoelectronic applications. High-quality transparent conductor oxide films ITO, AZO, and IZO were deposited on polyethylene terephthalate by PLD, an important experimental parameter being the target-substrate distance. The TCO films present a high transparency (>95%) and a reduced electrical resistivity (5 × 10 −4 Ωcm) characteristics very useful for their integration in the flexible electronics. In x Zn 1−x O films with a compositional library were obtained by CPLD. These films are featured by a high optical transmission (>95%), the lowest resistivity (8.6 × 10 −4 Ωcm) being observed for an indium content of about 44-49 at.%. Organic heterostructures based on arylenevinylene oligomers (P78 and P13) or arylene polymers (AMC16 and AMC22) were obtained by MAPLE. In the case of ITO/P78/Alq3/Al heterostructures, a higher current value is obtained when the film thickness increases. Also, a photovoltaic effect was observed for heterostructures based on AMC16 or AMC22 deposited on ITO covered by a thin layer of PEDOT:PSS. Due to their optical and electrical properties, such organic heterostructures can be interesting for the organic photovoltaic cells (OPV) applications.
