“…The laser beam is then focused through the transparent carrier at the thin-film/carrier interface and transfers the irradiated area of the film onto the substrate. The experimental apparatus is described in detail elsewhere [21,22]. As a laser source we use the 4 th harmonic of a Q-switched Nd:YAG laser system (4 ns pulse duration, 266 nm wavelength).…”

We report the fabrication of electrically functional polyaniline thin-film microdevices. Polyaniline films were printed in the solid phase by Laser Induced Forward Transfer directly between Au electrodes on a Si/SiO2 substrate. To apply solid-phase deposition, aniline was in situ polymerized on quartz substrates. Laser deposition preserves the morphology of the films and delivers sharp features with controllable dimensions. The electrical characteristics of printed polyaniline present ohmic behavior, allowing for electroactive applications. Results on gas sensing of ammonia are presented.Comment: In Pres

“…4(b), in the low frequency regime (10 −2 Hz), when the AC and DC conductivities can be compared, the conductivity of the LIFTed lines is approximately 40 pS m −1 (4 × 10 −11 S m −1 ), which is in agreement with the value reported in the literature for PPV. 23 Although LIFT of conducting polymers, such as polyaniline and poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylene vinylene], has been demonstrated, 24,25 to the best of our knowledge the results addressed herein are the first report on the printing of pure PPV, one of the most relevant polymers in the category. It is worth pointing out that we employed a single layer of PPV as donor material, without the use of a dynamic release layer or nanomaterial layer, as usually performed when LIFTing solid phase.…”

Conjugated polymers are important materials for optical applications, among which poly(p‐phenylene vinylene) (PPV) has a major role due to its applicability in sensors, organic light‐emitting diodes and large area displays. Despite advances on the synthesis of PPV‐based polymers and the improvements of their properties, its printing process, in particular involving the solid phase, remains unsuitable for the development of electro‐optical microcircuits. This paper demonstrates the printing of PPV from the solid phase in 2D micropatterns. Such an achievement was performed using laser induced forward transfer with femtosecond pulses, which allows area‐selective deposition within reduced scales as thin as ca 100 nm and 5 µm wide. Raman, fluorescence and electrochemical impedance spectroscopies confirm that the printed PPV micropatterns have the same structure, emission spectrum and conductivity as the target material, revealing the conservation of their original properties even after laser irradiation. The printing process was carried out using PPV films, overcoming the insolubility issue of this material. The optical and electrical characterization of the transferred PPV demonstrates the potential of this method for the patterning of electro‐optical microdevices, since luminescence and electrical conductivity were preserved. © 2018 Society of Chemical Industry

“…Additionally, more fields of applications are being proposed for deposition of materials via LIFT. In particular, photovoltaic technology seems to be a potential candidate that might take advantage of the LIFT technology for the deposition of a large variety of materials of both inorganic and organic nature [4][5][6]. In general, direct write (DW) techniques exhibit the advantage of avoiding the use of photolithography steps and of serigraphy masks, thus making these techniques a suitable and flexible alternative when different types of patterns and structures need to be defined [7].…”

a b s t r a c tIn this work the Laser Induced Forward Transfer (LIFT) technique is investigated to create n-doped regions on p-type c-Si substrates. The precursor source of LIFT consisted in a phosphorous-doped hydrogenated amorphous silicon layer grown by Plasma Enhanced Chemical Vapor Deposition (PECVD) onto a transparent substrate. Transfer of the doping atoms occurs when a sequence of laser pulses impinging onto the doped layer propels the material toward the substrate. The laser irradiation not only transfers the doping material but also produces a local heating that promotes its diffusion into the substrate. The laser employed was a 1064 nm, lamp-pumped system, working at pulse durations of 100 and 400 ns. In order to obtain a good electrical performance a comprehensive optimization of the applied laser fluency and number of pulses was carried out. Subsequently, arrays of n + p local junctions were created by LIFT and the resulting J-V curves demonstrated the formation of good quality n+ regions. These structures were finally incorporated to enhance the front contact in conventional silicon heterojunction solar cells leading to an improvement of conversion efficiency.
