“…After isolation of compound 11 , we focused on the synthesis of tetracyano‐substituted ferrocene structures. In the light of our previous knowledge, strong acceptors may lead to novel optoelectronic properties . Therefore, Ca‐Re reactions were used for the synthesis of ferrocene structures.…”

Small organic molecules are promising candidates for cheaper, flexible and good‐performance sources for organic solar cells (OSCs) due to their easy fabrication, low cost and slightly cheaper processing. However, the lower power conversion efficiency of OSCs is the main problem for their applications. Ferrocene structures could be the best candidates for the active layers of OSCs due to their unique properties such as thermal and chemical stability. The electrochemical, electro‐optical and solar cell performances of 2,5‐dicyano‐3‐ferrocenyl‐4‐ferrocenylethynylhexa‐2,4‐dienedinitrile (DiCN‐Fc) structures were investigated. First, the electrochemical and electro‐optical properties were examined for finding the highest occupied and lowest unoccupied molecular orbital values and bandgap of DiCN‐Fc. The best photovoltaic performance was obtained with 7 wt% of DiCN‐Fc loading, with a power conversion efficiency of about 4.27%. In the light of our investigations, ferrocenyl‐substituted small organic molecules could contribute to the development of organic photovoltaic devices.

“…Polymer:NFA blend solutions were prepared from 2:3 (mass% ratio) mixtures. The synthesis of AnE-PVstat is described elsewhere (Egbe et al 2010;Kivrak et al 2017a;Kivrak et al 2017b). In order to compare with a standard acceptor material, PCBM (Solenne) was used as received.…”

Organic solar cells based on anthracene-containing PPE–PPVs and non-fullerene acceptors

Lately, non-fullerene acceptors (NFAs) have received increasing attention for use in polymerbased bulk-heterojunction (BHJ) organic solar cells (OSCs), as improved photovoltaic performance compared to classical polymer-fullerene blends could be demonstrated. In this study, polymer solar cells based on a statistically substituted anthracene-containing poly(pphenyleneethynylene)-alt-poly(p-phenylenevinylene)s (PPE-PPVs) copolymer (AnE-PVstat) as donor in combination with a number of different electron accepting materials were investigated. Strong photoluminescence quenching of the polymer donor indicates intimate intermixing of both materials. However, the photovoltaic performances were found to be poor compared to blends that use fullerene as acceptor. Time-delayed collection field (TDCF) measurements demonstrate: charge generation is field-independent, but bimolecular recombination processes limit the fill factor and thus the efficiency of devices.

“…(Figure 11). [ 196 ] This introduced furan provided a good solubility and planarity for the three small molecules, and the reasonable stacking stage filled the spaces between P3HT and PCBM during microphase separation. Consequently, OSCs with adding additives exhibited improved PCE than the untreated case.…”

The state‐of‐the‐art bulk‐heterojunction (BHJ)‐type organic solar cells (OSCs) have exhibited power conversion efficiencies (PCEs) of exceeding 18%. Thereinto, thiophene and its fused‐ring derivatives play significant roles in facilitating the development of OSCs due to their excellent semiconducting natures. Furan as thiophene analogue, is a ubiquitous motif in naturally occurring organic compounds. Driven by the advantages of furan, such as less steric hindrance, good solubility, excellent stacking, strong rigidity and fluorescence, biomass derived fractions, more and more research groups focus on the furan‐based materials for using in OSCs in the past decade. To systematically understand the developments of furan‐based photovoltaic materials, the relationships between the molecular structures, optoelectronic properties, and photovoltaic performances for the furan‐based semiconductor materials including single furan, benzofuran, benzodifuran (BDF) (containing thienobenzofuran (TBF)), naphthodifurans (NDF), and polycyclic furan are summarized. Finally, the empirical regularities and perspectives of the development of this kind of new organic semiconductor materials are extracted.
