“…Thus, DPP-DTT can be used as an additive for improving the absorption of other polymers (efficiency increased from 7.58 to 8.33% by adding 1 wt.% DPP-DTT [130]) or can be integrated as an absorber beside an acceptor material (6.2% efficiency [131]). It was already proved that the MAPLE-deposited DPP-DTT films can be useful in the PV domain [87]. Arylene based polymers, poly[N-(2-ethylhexyl)2.7-carbazolyl vinylene] (AMC16) and poly[N-(2-ethylhexyl)2.7-carbazolyl 1.4-phenyleneethynylene] (AMC22), presenting band gap values of ~2.5 eV, were also evaluated as donors in the PV cell structures [88].…”

“…Fullerene C60 and the soluble fullerene derivatives ( [6,6]-phenyl-C61-butyric acid methyl ester (PCBM), [6,6]-Phenyl-C61 butyric acid butyl ester (PCBB), [6,6]-phenyl C71 butyric acid methyl ester (PC71BM)) are typically used as acceptor materials (as stacked layers or blended with the donor materials) in the OPV cell structures deposited using MAPLE [38,70,87,120]. However, other non-fullerene acceptor materials were also investigated.…”

“…M. Socol (2020) studied a low band gap polymer, DPP-DTT and fullerene C60 as bulk heterojunction layers deposited using MAPLE (KrF* laser source, λ = 248 nm) [87]. In the laser transfer of the organic layers, targets prepared from 3 g/L organic components of mixture compounds DPP-DTT:C60 blends in weight ratios of 1:1, 1:2 and 1:3 in chloroform were used, with the number of the laser pulses being tuned.…”

“…The organic and hybrid layers deposited using MAPLE were usually applied in the biomedical area as antimicrobial coatings [73][74][75][76][77], bioactive coatings [78], tissue regeneration systems [79,80], bone regeneration systems [81], drug delivery systems [82][83][84], etc. However, the potential applications of the MAPLE deposited layers in other fields concerning organic photovoltaic cells [38,40,70,[85][86][87][88], hybrid photovoltaic cells [39,89,90], polymer light emitting diodes [91,92], antireflective coatings [93], photo-responsive coatings [82], non-linear optical materials [94][95][96], transparent supercapacitor electrodes [97] and sensing materials for various gases [98][99][100][101][102][103][104] has also been envisaged. The following are some examples of organic and hybrid layers deposited using MAPLE on various substrates, which were reported in studies published in the last three years: (i) poly(methyl methacrylate) bilayer antireflective coatings were designed by combining spin coating and MAPLE, the MAPLE deposited surface layer exhibiting a biomimic moth-eye structure on a glass substrate to trap the incident light [93]; (ii) photo-responsive coatings based on azobenzene-containing polymers nanocapsules were deposited on flat substrates (KBr and polyethylene) and 3D substrates (acr...…”

Human society’s demand for energy has increased faster in the last few decades due to the world’s population growth and economy development. Solar power can be a part of a sustainable solution to this world’s energy need, taking into account that the cost of the renewable energy recently dropped owed to the remarkable progress achieved in the solar panels field. Thus, this inexhaustible source of energy can produce cheap and clean energy with a beneficial impact on the climate change. The considerable potential of the organic photovoltaic (OPV) cells was recently emphasized, with efficiencies exceeding 18% being achieved for OPV devices with various architectures. The challenges regarding the improvement in the OPV performance consist of the selection of the adequate raw organic compounds and manufacturing techniques, both strongly influencing the electrical parameters of the fabricated OPV devices. At the laboratory level, the solution-based techniques are used in the preparation of the active films based on polymers, while the vacuum evaporation is usually involved in the deposition of small molecule organic compounds. The major breakthrough in the OPV field was the implementation of the bulk heterojunction concept but the deposition of mixed films from the same solvent is not always possible. Therefore, this review provides a survey on the development attained in the deposition of organic layers based on small molecules compounds, oligomers and polymers using matrix-assisted pulsed laser evaporation (MAPLE)-based deposition techniques (MAPLE, RIR-MAPLE and emulsion-based RIR-MAPLE). An overview of the influence of various experimental parameters involved in these laser deposition methods on the properties of the fabricated layers is given in order to identify, in the forthcoming years, new strategies for enhancing the OPV cells performance.
