Abstract Leveraging breakthroughs in Y‐series nonfullerene acceptors (NFAs), organic solar cells (OSCs) have achieved impressive power conversion efficiencies (PCEs) exceeding 19%. However, progress advancing OSCs has decelerated due to constraints realizing the full potential of NFAs. Herein, a simple yet effective solid additive‐induced preaggregation control method employing 2‐chloro‐5‐iodopyridine (PDCI) is reported unlock Specifically, PDCI interacts predominantly with NFAs enabling...
A set of o-carborane-appended π-conjugated fluorophores and their light-emitting properties in the solid state are reported. The aggregation-induced emission enhancement (AIEE) exhibited for one fluorenyl derivatives paved way to successfully preparing o-carborane-containing organic nanoparticles (NPs) homogeneously dispersed aqueous media that maintain luminescence properties. Notably, NPs processed as thin films also show high fluorescence efficiency, suggesting potential optical...
Abstract Relatively thick‐film organic photovoltaics (OPVs) are desirable to spark commercialization through mass‐printing methods. Thickness‐resilient donor:acceptor blends are, however, scarce and not fully understood. The interplay between electronic, optical, microstructural properties of the photoactive layer (PAL) generates a multi‐parametric space where rationalization is far from trivial. In this work, high‐throughput experimentation, simulations, machine learning (ML) methods...
Abstract Thermoelectrics have emerged as a strategy for solar‐to‐electricity conversion, they can complement photovoltaic devices IR harvesters or operate stand‐alone systems often under strong light and heat concentration. Inspired by the recent success of inorganic‐based solar thermoelectric generators (STEGs), in this manuscript, potential benchmark organic materials harvesting is evaluated. It shown that inherent properties semiconductors allow possibility fabricating STEGs (SOTEGs)...
Abstract Thermal annealing alters the morphology of organic donor-acceptor bulk-heterojunction thin films used in solar cells. Here, we studied influence thermal on blends amorphous regio-random (RRa) and semi-crystalline regio-regular (RR) poly (3-hexylthiophene) (P3HT) fullerene derivative [6,6]-phenyl-C 60 -butyric acid methyl ester. Since P3HT:PCBM blend is one most OPV community, existing research provides a solid foundation for us to compare benchmark our innovative characterization...
Abstract Organometallic coordination polymers (OMCPs) are a promising class of thermoelectric materials with high electrical conductivities and thermal resistivities. The design criteria for these materials, however, remain elusive so far material modifications have been focused primarily on the nature metal cation to tune properties. Herein, an alternative approach is described by synthesizing new organic ligands OMCPs, allowing modulation properties novel OMCP over several orders...
Thermal annealing is one of the most commonly applied post-processing techniques to improve organic solar cell (OSC) performance. In this work, cells based on PBDB-T:IT-2F bulk heterojunctions were subjected thermal at different stages fabrication process investigate their impact photovoltaic parameters. Various electro-optical measurement used reveal charge recombination dynamics and extraction process. According our findings, both a single-step postprocessing procedure two-step improved...
