“…The applications projected in this study are based on the knowledge of properties and rationality, however it should be emphasized that practical experiments need to be performed to verify the performance (figure of merit, coefficient of performance, etc) and device strategies to overcome the challenges [81]. As in most computational materials research, our study is intended to provide the starting motivation for more rigorous experimental work in this direction [82,83]. Figure 5.…”

There is significant interest in hybrid organic-inorganic (HOI) compounds since these materials offer multiple functionalities and properties that can be tailored at the mesoscopic and nanoscale levels. HOIs investigated for photovoltaic applications typically contain lead or mercury. There is considerably less work done on Zn-based HOIs. These could potentially be considered in biomedical applications due to presence of organic components and the biocompatibility of Zn cations. Using a systematic materials selection approach, we have carried out a detailed search of Zn-HOI compounds in two comprehensive experimental crystallographic repositories: Inorganic Crystal Structure Database and American Mineralogist Crystal Structure Database. Thirteen Zn-HOI compounds are discovered: CuZnO 2 (CO 3 ), Zn(C 2 O 4 ), ((CH 3 ) 2 NH 2 )Zn 3 (PO 4 )(HPO 4 ) 2 , (CH 3 NH 3 )Zn 4 (PO 4 ) 3 , Zn(N(CH 2 PO 3 H) 3 )(H 2 O) 3 , (CH 3 NH 3 )Zn(HCO 2 ) 3 , Zn 4 (CO 3 ) 2 , Zn 8 (HPO 4 ) 16 (C 2 H 8 N) 8 , Zn 5 (CO 3 ) 2 , (Mg 2 Zn) 8 (CO 3 ) 2 (OH), Zn 7 (CO 3 ) 2 (OH) 10 , Ca 3 Zn 2 (PO 4 )CO 3 (OH).2H 2 O, and Zn(CO 3 ). We have then performed first principles calculations via density functional theory with hybrid functional treatment to determine the electronic band gap and optical response of these materials. Our computations show that eleven of the thirteen compounds have insulating properties with band gaps ranging from 2.8 eV to 6.9 eV. Ten of these are found to have a high absorbance in the far ultra-violet (FUV) region of 200-112 nm wavelength. For example, the absorption coefficient of (CH 3 NH 3 )Zn(HCO 2 ) 3 is ∼0.75×10 5 cm −1 for F 2 excimer laser energy (wavelength ∼157 nm) which is more than three orders higher than the average tissue absorbance (∼10 1.5 cm −1 ) and the refractive index of 1.85 is larger than typical biological matter which is in the range 1.36-1.49. These results suggest that Zn-HOIs could potentially find applications in photothermolysis and UV protection.

“…These three environmentally friendly materials are featured by morphologically rich families of nanostructures (spheres, wires, rods, tubes, tetrapods, needles, spindle-shaped platelets, etc.) that can be relatively easily obtained by numerous wet and dry techniques [ 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 ]. Figure 3 illustrates some nanostructures based on ZnO or CuO with different morphologies (particles, prisms, flowers, flakes, fibers and wires) prepared by straightforward paths such as chemical precipitation [ 44 , 45 ], electroless deposition [ 46 ], biomorphic mineralization [ 47 ], and thermal oxidation in air [ 48 , 49 ].…”

“…Laser-processing technique, i.e., Matrix-Assisted Pulsed Laser Evaporation (MAPLE) is a relatively new method being developed in the late 1990s by the US Naval Research Laboratory for processing organic compounds (especially polymers) layers with the preservation of their chemical structure during the deposition [ 59 ]. Thus, using small quantities of material (typically below 5 wt%), MAPLE allows the deposition of organic or hybrid layers for OPV [ 60 , 61 , 62 , 63 ] or HPV [ 44 , 64 , 65 ], respectively. Compared to the pulsed laser deposition (PLD), a technique employing a solid target obtained from pressed powder or pellets, MAPLE involves a frozen target prepared from the material that is intended to be deposit as thin film and a suitable solvent, used as matrix [ 66 , 67 ].…”

Continuing growth in global energy consumption and the growing concerns regarding climate change and environmental pollution are the strongest drivers of renewable energy deployment. Solar energy is the most abundant and cleanest renewable energy source available. Nowadays, photovoltaic technologies can be regarded as viable pathways to provide sustainable energy generation, the achievement attained in designing nanomaterials with tunable properties and the progress made in the production processes having a major impact in their development. Solar cells involving hybrid nanocomposite layers have, lately, received extensive research attention due to the possibility to combine the advantages derived from the properties of both components: flexibility and processability from the organic part and stability and optoelectronics features from the inorganic part. Thus, this review provides a synopsis on hybrid solar cells developed in the last decade which involve composite layers deposited by spin-coating, the most used deposition method, and matrix-assisted pulsed laser evaporation, a relatively new deposition technique. The overview is focused on the hybrid nanocomposite films that can use conducting polymers and metal phthalocyanines as p-type materials, fullerene derivatives and non-fullerene compounds as n-type materials, and semiconductor nanostructures based on metal oxide, chalcogenides, and silicon. A survey regarding the influence of various factors on the hybrid solar cell efficiency is given in order to identify new strategies for enhancing the device performance in the upcoming years.

“…The selection of the most appropriate approach for fabricating the hybrid organic-inorganic structures depends on the device architecture (stacked layers or with BHJ). However, in the case of BHJ, spin-coating is the most applied preparation method, other techniques such as doctor blading, ink-jet printing or matrix assisted pulsed laser evaporation (MAPLE) [16,17] have recently started to be used. Laser evaporation-based approach developed to deposit organic thin films with either preservation or minimal degradation of the chemical structure of the raw materials, MAPLE involves a solid target obtained by freezing a mixture containing the organic material dissolved in a compatible solvent.…”

Matrix-assisted pulsed laser evaporation (MAPLE) was used to deposit hybrid nanocomposite thin films based on cobalt phthalocyanine (CoPc), C60 fullerene and ZnO nanoparticles. The inorganic nanoparticles, with a size of about 20 nm, having the structural and optical properties characteristic of ZnO, were chemically synthesized by a simple precipitation method. Furthermore, ZnO nanoparticles were dispersed in a dimethyl sulfoxide solution in which CoPc and C60 had been dissolved, ready for the freezing MAPLE target. The effect of the concentration of ZnO nanoparticles on the structural, morphological, optical and electrical properties of the CoPc:C60:ZnO hybrid nanocomposite layers deposited by MAPLE was evaluated. The infrared spectra of the hybrid nanocomposite films confirm that the CoPc and C60 preserve their chemical structure during the laser deposition process. The CoPc optical signature is recognized in the ultraviolet–visible (UV–Vis) spectra of the obtained layers, these being dominated by the absorption bands associated to this organic compound while the ZnO optical fingerprint is identified in the photoluminescence spectra of the prepared layers, these disclosing the emission bands linked to this inorganic semiconductor. The hybrid nanocomposite layers exhibit globular morphology, which is typical for the thin films deposited by MAPLE. Current-voltage (J-V) characteristics of the structures developed on CoPc:C60:ZnO layers reveal that the addition of an appropriate amount of ZnO nanoparticles in the CoPc:C60 mixture leads to a more efficient charge transfer between the organic and inorganic components. Due to their photovoltaic effect, structures featuring such hybrid nanocomposite thin films deposited by MAPLE can have potential applications in the field of photovoltaic devices.
