“…Therefore, in recent years, a great deal of effort has gone into developing non-fullerene acceptors that combine good stability, easy synthesis, strong visible and near-infrared absorption, and the ability to adjust energy levels. The use of polymer donors having complementary absorption spectra with non-fullerene acceptors resulted in the PCE levels of 10–14% often reported [ 58 , 63 , 64 ]. Aromatic compounds containing silicon in their structure constitute an attractive building block due to their unique electronic structures, which consist of low LUMO energy levels and relatively small band gaps, due to the interaction between the silicon σ* orbital and the π* butadiene orbital.…”

Over the past two decades, both fundamental and applied research in conducting polymers have grown rapidly. Conducting polymers (CPs) are unique due to their ease of synthesis, environmental stability, and simple doping/dedoping chemistry. Electrically conductive silicone polymers are the current state-of-the-art for, e.g., optoelectronic materials. The combination of inorganic elements and organic polymers leads to a highly electrically conductive composite with improved thermal stability. Silicone-based materials have a set of extremely interesting properties, i.e., very low surface energy, excellent gas and moisture permeability, good heat stability, low-temperature flexibility, and biocompatibility. The most effective parameters constructing the physical properties of CPs are conjugation length, degree of crystallinity, and intra- and inter-chain interactions. Conducting polymers, owing to their ease of synthesis, remarkable environmental stability, and high conductivity in the doped form, have remained thoroughly studied due to their varied applications in fields like biological activity, drug release systems, rechargeable batteries, and sensors. For this reason, this review provides an overview of organosilicon polymers that have been reported over the past two decades.

“…4 The most important part of the BHJ type of solar cell is the active layer, which generally consists of electron-rich donor materials and electron-deficient acceptor materials. 5 As for acceptors, fullerene and its derivatives are potential candidates that provide several advantages in the field of organic photovoltaic cells with sufficient electron affinity (EA), high electron transporting capacity, excellent charge separation, and lower lowest unoccupied molecular orbital (LUMO) to accept the electrons from the donor, leading to high power conversion efficiency (PCE). 6,7 In spite of having some remarkable properties with high PCE, it still possesses some drawbacks, such as their wide band gap, weak absorption of solar radiation, thermal and photochemical instability, difficulty in the purification process, high production cost, etc.…”

The design and development of novel and efficient donor−π−acceptor (D−π−A) type conjugated systems has attracted substantial interest in the field of organic electronics owing to their intriguing properties. In this paper, we have designed seven new and efficient D−π−A type conjugated systems (M1−M7) by a variety of π-linkers with triphenylamine (TPA) as the electron donor and diphenyldiketopyrrolopyrrole (DPP) as the electron acceptor using density functional theory (DFT) formalism for organic solar cells (OSCs). The π-linker has been substituted between the donor and acceptor for efficient electron transfer. Here, our primary focus is on narrowing the highest occupied molecular orbital−lowest unoccupied molecular orbital gaps, electronic transition, charge transfer rate, reorganization energies, and the theoretical power conversion efficiencies (PCEs). Our study reveals that the designed compounds exhibit excellent charge transfer rates. The absorption properties of the compounds have been examined using the time-dependent density functional theory (TD-DFT) method. The TD-DFT study shows that compound M2 possesses the highest absorption maxima with a maximum bathochromic shift. For a better understanding of the electron transport process of our designed compounds, we have designed donor/acceptor (D/A) blends, and each of the developed blends (FREA/M1−M7) can encourage charge carrier separation. According to the photovoltaic performance of the D/A blends, compound FREA-M2, which has a theoretical PCE of 16.53%, is the most appealing choice for use in OSCs. We expect that by thoroughly examining the relationship between structure, characteristics, and performance, this work will serve as a roadmap for future research and development of TPA-DPP-based photovoltaic materials.

“…It confers thiophene-based CPPs improved conductivity of electrons and holes. For this reason, CPPs based on this type of building blocks have been widely employed in fields such as batteries, [10,11] field-effect transistors, [12] solar cells, [13] or photocatalysis, [14,15] among others. Thus, several authors have employed building blocks based on thiophene moieties in the synthesis of a huge number of CPPs.…”

Herein, the design and synthesis of a couple of CPPs based on thienoacene units (named as IEP‐14 and IEP‐15, stand for IMDEA Energy Polymer numbers 14 and 15) are described, which show high BET surface areas, good photo(thermal) stabilities, and appropriate electronic alignment with TiO2 to prepare hybrids (named as IEP‐x@T‐10, X = 14 and 15, being 10 wt% of polymer loading). It is shown that the simultaneous UV–vis irradiation of both materials leads to better H2 production (ca. 925 and 827 µmol g−1 h−1 by IEP‐15@T‐10 and IEP‐14@T‐10, 12 and 11‐fold higher production than bare TiO2) than the solely irradiation at visible of the CPPs (ca. 124 and 90 µmol g−1 h−1 by IEP‐15@T‐10 and IEP‐14@T‐10 when TiO2 is photocatalytically inactive). The reason is attributed to the charge‐transfer mechanisms that occur between the counterparts of the hybrid material: in the first case it consists in a Z‐scheme charge transfer mechanism, while in the second one is a sensitization charge transfer mechanism. Both mechanisms are elucidated by advanced techniques. Furthermore, in a gas phase CO2 photoreduction test, IEP‐15@T‐10 shows sixfold higher CH4 evolution than TiO2, which result in a selectivity shift from CO to CH4 (i.e., >26% greater selectivity than bare TiO2).
