Today, flexible and lightweight electronics are regarded as a viable alternative to conventional rigid heavy devices in various application fields. In the optoelectronic area, organic semiconductors offer advantages such high absorption coefficients, low processing temperatures, mechanical flexibility compatibility with plastic substrates, while inorganic nanostructures provide good electronic properties thermal stability. Thus, composite films enhanced can be achieved by inserting within...
Nowadays, the development of devices based on organic materials is an interesting research challenge. The performance such strongly influenced by material selection, properties, design, and manufacturing process. Usually, buckminsterfullerene (C60) employed as electron transport in photovoltaic (OPV) due to its high mobility. However, considering low solubility, there have been many attempts replace it with more soluble non-fullerene compounds. In this study, bulk heterojunction thin films...
Nanocomposite films based on macrocyclic compounds (zinc phthalocyanine (ZnPc) and 5,10,15,20-tetra(4-pyridyl) 21H,23H-porphyrin (TPyP)) metal oxide nanoparticles (ZnO or CuO) were deposited by matrix-assisted pulsed laser evaporation (MAPLE). 1,4-dioxane was used as a solvent in the preparation of MAPLE targets that favor deposition with low roughness, which is key feature for their integration structures optoelectronic applications. The influence addition ZnO (~20 nm size) CuO (~5...
Abstract Laser thin layer deposition technologies were applied to develop organic heterostructures on flexible transparent conductive electrode (TCE). Flexible substrates such as glass (FG), polyethersulfone (PES), amorphous polyethylene terephthalate (PET-A) and biaxially-oriented (PET-B) employed assess the influence of substrate type optical electrical characteristics devices. For comparison reason, fabricated rigid commercially available indium tin oxide (ITO)-coated PET. Hence, coated...
Bimetallic nanostructures have the potential to become new generation candidates for applications in catalysis, electronics, optoelectronics, biosensors and also surface-enhanced Raman Spectroscopy (SERS). The bimetallic nanocrystals offer additional properties over single metal components such as improved electromagnetic corrosion protection. This work presents a simple inexpensive method fabricate large area biplasmonic (bimetallic) substrates, employing DC magnetron sputtering, picosecond...
Lately, there is a growing interest in organic photovoltaic (OPV) cells due to the materials’ properties and compatibility with various types of substrates. However, their efficiencies are low relative silicon ones; therefore, other ways (i.e., electrode micron/nanostructuring, synthesis new materials, use additives) improve performances still being sought. In this context, we studied behavior common bulk heterojunction (P3HT:PC70BM) deposited by matrix-assisted pulsed laser evaporation...
