“…Rubrene (5,6,11,12-tetraphenylnaphthacene) is an organic semiconductor featured by a long exciton diffusion length and high charge mobility (20 cm 2 V −1 s −1 in single crystals) [116,117]. Usually used in the organic field-effect transistor area, rubrene is also involved as an active or donor compound in the OPV devices, as was reviewed in 2021 by Liu [118].…”

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.

“…1,2 The high fluorescence quantum yield (F PL ) of Rub was extensively exploited in organic light-emitting devices (OLEDs) for light emission, both in the 1st generation fluorescent 3 and the latest generation hyperfluorescent 4,5 OLEDs. Meanwhile, the high carrier mobility of crystalline Rub facilitated the development of important devices 6 such as organic field-effect transistors, 7 organic diodes 8 and organic solar cells. 9,10 Besides applications in organic electronics, Rub has found niche uses in photoredox catalysis 11 and organic spintronics.…”

“…In this paper, we implement a method to micropattern organic single crystals using industrial standard microfabrication techniques based on direct write laser for the definition of the PR mask and pattern transfer by RIE. Rubrene, [37,38] an organic semiconductor with the molecular structure presented in Figure 1a, is used as a model to demonstrate the feasibility of such approach to obtain micrometric photosensors with precisely defined dimensions. This concept can be extended to other conjugated organic systems.…”

Light detection technologies are of interest due to their applications in energy conversion and optical communications. Single-crystal organic semiconductors, such as rubrene, present high detectivities and charge carrier mobility, making them attractive for light-sensing applications. Growth of high crystallinity organic crystals is achieved using vapor processes, forming crystals of arbitrary shapes and orientations and requiring posterior patterning processes. However, patterning the organic semiconductors using industrystandard microfabrication techniques is not straightforward, as these often cause irreversible damage to the crystals. Here the fabrication of patterned micrometric rubrene photosensors is demonstrated through a combination of photolithography and Reactive Ion Etching steps. Protective layers during microfabrication minimize degradation of optoelectronic properties of the organic single crystals during fabrication. Crystals undergoing the patterning process presented a survival rate of 39%. Photoresponse values of up to 41 mA W −1 are obtained under illumination at 500 nm. This opens a route for the industrial-scale fabrication process of high-performance optoelectronic devices based on organic crystals semiconductors.
