“…Optically, the nanoparticle active layer exhibits light absorption relatively similar to Bulk heterojunction (BHJ) active layer. As the results of optical modelling confirmed that the optimum Jsc of NPs compared with BHJ has no more two magnitude values [8], However, the problem of NPs device is the charge transfer (charge Mobility) in active layer due to the boundaries of NPs in comparison to BHJ structure that has non-structural between donor/acceptor, a free charge has high probability to cross active layer and collected out the BHJ device [14]. In general optical modeling here is utilized to give an idea of the optimum performance of the OPV -device before laboratory preparation relying on UV-vis measurements for active layer thin film.…”

Nanoparticle Organic photovoltaic devices (NPs-OPVs) have received a great attention due to utilizing eco-friendly material to prepare active layer in OPV without any hazard on the environment. Herein, poly (3-hexylthiophene) (P3HT) is employed as a donor with a new and low cost fullerene ICxA to prepare NPs photoactive layer. The NPs photoactive layer is prepared by minemulation method generating core-shell structure. A DLS and STEM measurements are preformed to calculate the particle size (which is around 40 nm). Optical properties then demonstrated for P3HT: ICxA NPs compared with P3HT: PCBM NPs by using UV-vis measurements. The finding of this report reveals that the low cost and a new acceptor ICxA behaviour relativity agree with PCBM as commercial material in NPs structure.

Molecular electronics is a scientific endeavour that, for 60 years, has offered the promise of new technologies in which molecules integrate with, if not entirely replace, semiconductor electronics. En route to the attainment of these ambitious goals, central aspects underpinning the pursuit of this science have proven critical to the development of related technologies, including organic photovoltaics (OPV) and organic light-emitting diodes (OLEDs). Looking ahead, new opportunities in the field abound, from the study of molecular charge transport and the elucidation of molecular reaction mechanisms, to the development of biocompatible and degradable electronics, and the construction of novel chemical sensors with exquisite sensitivity and specificity. This article reviews historical developments in molecular electronics, with a particular focus on Australia’s contributions to the area. Australia’s current activity in molecular electronics research is also summarised, highlighting the capacity to both advance fundamental knowledge and develop new technologies. Scientific aspects considered include capabilities in: single molecule and molecular–monolayer junction measurement; spectroscopic analysis of molecular components and materials; synthetic chemistry; computational analysis of molecular materials and junctions; and the development of theoretical concepts that describe the electrical characteristics of molecular components, materials and putative device structures. Technological aspects considered include various aspects of molecular material design and implementation, such as: OPV and OLED construction, sensing technologies and applications, and power generation from heat gradients or friction. Missing capabilities are identified, and a future pathway for Australian scientific and technological development envisaged.

“…105 More recently, Al-Mudhaffer et al reported that the core-shell morphology can be modulated by using active materials with higher miscibilities, such as P3HT: indene C60bisadduct (ICBA). 106 Pan et al observed higher PL intensities using o-xylene as an organic solvent for the preparation of nanoparticles through miniemulsion, in comparison to dispersions using chloroform as an organic solvent. They concluded that the use of o-xylene led to the formation of more segregated domains within the nanoparticle.…”

Development of carbon neutral and sustainable energy sources should be considered as a top priority solution for the growing worldwide energy demand. Photovoltaics are a strong candidate, and more specifically organic photovoltaics (OPV), enabling the design of flexible, light-weight, semi-transparent and low-cost solar cells. However, the active layer of OPV is, for now, mainly deposited from chlorinated solvents, harmful for the environment and for human health. Active layers processed from health and environmentally friendly solvents have over recent years formed a key focus topic of research, with the creation of aqueous dispersions of conjugated polymer nanoparticles arising. These nanoparticles are formed from organic semi-conductors (molecules and macromolecules) initially designed for organic solvents. The topic of nanoparticle OPV has gradually garnered more attention, up to a point where in 2018 it was identified as a "trendsetting strategy" by leaders in the international OPV research community. Hence, this review has been prepared to provide a timely roadmap of the formation and application of aqueous nanoparticle dispersions of active layer components for OPV. We provide a thorough synopsis of recent developments in both nanoprecipitation and miniemulsion for preparing photovoltaic inks, facilitating readers in acquiring a deep understanding of the crucial synthesis parameters affecting particle size, colloidal concentration, ink stability, and more. This review also showcases the experimental levers for identifying and optimizing the internal donor-acceptor morphology of the nanoparticles, featuring cutting-edge X-ray spectromicroscopy measurements reported over the past decade. The different strategies to improve the incorporation of these inks into OPV devices and to increase their efficiency (to the current record of 7.5%) are reported, in addition to critical design choices of surfactant type and the advantages of single-component vs. binary nanoparticle populations. The review naturally culminates by presenting the upscaling strategies in practice for this environmentally friendly and safer production of solar cells.
