Anic solvents (chlorobenzene, chloroform, tetrahydrofuran, xylene and toluene). Poly[2,6-(four,4-bis-(2-ethylhexyl)-4H-cyclopenta[2,1b;3,4-b ]dithiophene)-alt-4,7-(two,1,3-benzothiadiazole)] (PCPDTBT) is definitely an effective polymer effectively made use of within the PV cells resulting from its band gap worth of 1.5 eV and great charge transport properties [69,128]. Poly[2,5-(2-octyldodecyl)-3,6-diketopyrrolopyrrole-alt-5,five(2,5-di(thien-2-yl)thieno [3,2-b]thiophene)] (DPP-DTT) includes a band gap worth of 1.7 eV [129] and also a high hole mobility ( ten cm2 /Vs [130]) becoming utilized in each PV cells and organic fieldeffect transistors (OFET) structures [131,132]. Hence, DPP-DTT can be made use of as an additive for enhancing the absorption of other polymers (efficiency increased from 7.58 to 8.33 by adding 1 wt. DPP-DTT [130]) or is 4-Epianhydrotetracycline (hydrochloride) Epigenetic Reader Domain usually integrated as an absorber beside an acceptor material (six.two efficiency [131]). It was currently proved that the MAPLE-deposited DPP-DTT films may be helpful within the PV domain [87]. Arylene based polymers, poly[N(2-ethylhexyl)two.7-carbazolyl vinylene] (AMC16) and poly[N-(2-ethylhexyl)2.7-carbazolyl 1.4-phenyleneethynylene] (AMC22), presenting band gap values of two.five eV, were also evaluated as donors inside the PV cell structures [88]. Fullerene C60 plus 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 commonly used as acceptor materials (as stacked layers or blended using the donor materials) within the OPV cell structures deposited making use of MAPLE [38,70,87,120]. Nonetheless, other non-fullerene acceptor supplies have been also investigated. Poly(5-(2-(ethylhexyloxy)-2-methoxycyanoterephthalyliden) (MEH-CN-PPV) is usually a cyano-PPV derivative luminescent polymer having a band gap value of two eV [61,133]. Similar to its perylene equivalent (PTCDA), 1,four,5,8-naphthalene-tetracarboxylic dianhydride (NTCDA) can be a highly symmetric, planar -conjugated molecule that was incorporated in various organic structures as an electron conducting [134,135] or as an exciton blocking layer [136]. Despite the fact that five,ten,15,20-tetra(4-pyrydil)21H,23H-porphyne (TPyP), a non-metallic phorphyrine presenting absorption bands in the visible range (similar to phthalocyanines) [137], is generally reported as a thin film obtained by vacuum evaporation, recently, this compound was deposited applying MAPLE [40]. N,N -bis-(1-dodecyl)perylene-3,four,9,ten tetracarboxylic diimide (AMC14), a perylene diimide derivative characterized by a superb solubility [85], is also applied as an acceptor in the OPV cells. 3. Organic Thin Films Deposited Utilizing MAPLE-Based Techniques for OPV Applications The a variety of organic layers based on modest molecule compounds, oligomers and polymers deposited making use of UV-MAPLE, RIR-MAPLE and FE-202845 Protocol emulsion-based RIR-MAPLE for PV applications will probably be further presented in this manner to emphasize the influence of experimental parameters like solvent type, emulsion chemistry, deposition substrate, polymer molecular weight, laser fluence and deposition configuration on the layer properties.Coatings 2021, 11,9 of3.1. Layers Depending on Little Molecule Compounds 3.1.1. Influence of your Laser Fluence A. Stanculescu (2011) investigated, for the initial time, the deposition of little molecule compounds for example ZnPc, PTCDA and Alq3 as a single layer or multilayer applying MAPLE (KrF laser source, = 248 nm) [115]. Inside the deposition of an organic layer on ITO substrates, laser fluences ranging from 166 to.
