This brief review summarizes non-fullerene acceptors based on perylene diimides used in bulk-heterojunction solar cells which were reported mainly during 2014–2016.
Abstract Low‐dimensional Ruddlesden–Popper perovskites (RPPs) exhibit excellent stability in comparison with 3D perovskites; however, the relatively low power conversion efficiency (PCE) limits their future application. In this work, a new fluorine‐substituted phenylethlammonium (PEA) cation is developed as spacer to fabricate quasi‐2D (4FPEA) 2 (MA) 4 Pb 5 I 16 ( n = 5) perovskite solar cells. The champion device exhibits remarkable PCE of 17.3% J sc 19.00 mA cm −2 , V oc 1.16 V, and fill...
Expanding sensing modes and improving catalytic performance of nanozyme-based analytical chemistry are beneficial to realizing the desired biosensing analytes. Herein, Schiff-base coupled with a novel catechol oxidase-like nanozyme (CHzyme) is designed constructed, exhibiting two main advantages, including (1) by nearly 2-fold compared only role CHzyme; (2) increasing designability output signal transduction cascade reaction. Thereafter, substrate based on reaction between CHzyme-catalyzed...
Modifying molecular conjugation has been demonstrated as an effective strategy to enhance the photovoltaic performance of non-fullerene small molecule acceptors (SMAs), which would regulate packing and nanoscale morphology in active layer organic solar cells (OSCs). Here, two novel SMAs PTIC-4Cl PT2IC-4Cl are designed synthesized by expanding core unit TB-4Cl one or directions. The effects how expand length on absorption property, energy levels, dipole moment, solubility studied via...
Abstract The realization of high‐efficiency organic solar cells (OSCs) from renewable sources will bring a real green energy technology. Benzo[1,2‐b:4,5‐b′]difuran (BDF) is such building block for photovoltaic polymers as it can be built furfural, which available trees and vegetables. However, the device performance BDF‐based limited by aggregation properties unfavorable active layer morphology. Herein, two new wide bandgap‐conjugated polymers, PFCT‐2F PFCT‐2Cl, are developed copolymerizing...
Substituting the hydrogen atoms on conjugated side chain of a wide-bandgap polymer J52 with chlorine can simultaneously increase Jsc, Voc, and FF nonfullerene OSCs, leading to an efficiency boost from 3.78 11.53%, which is among highest efficiencies for as-cast OSCs reported date. To illustrate impressive 3-fold PCE enhancement, chlorination effect optical properties energy levels polymers, film morphology, underlying charge dynamics systematically investigated. Grazing incidence wide-angle...
The geometries of acceptors based on perylene diimides (PDIs) are important for improving the phase separation and charge transport in organic solar cells. To fine-tune geometry, biphenyl, spiro-bifluorene, benzene were used as core moiety to construct quasi-three-dimensional nonfullerene PDI building blocks. molecular geometries, energy levels, optical properties, photovoltaic exciton kinetics systematically studied. structure–performance relationship was discussed well. Owing finest...
The performance of quasi-two-dimensional (Q-2D) perovskite solar cells (PSCs) strongly depends on the interface characteristics between hole transport material (HTM) and layer. In this work, we designed synthesized a series HTMs with triphenylamine-carbazole as core structure modified end groups chlorine bromine atoms. These show deeper highest occupied molecular orbital energy levels than commercial HTMs. This reduced band mismatch HTM layer facilitates efficient charge extraction at...
The incorporation of one 3,4-ethylenedioxythiophene (EDOT) building block into a diketopyrrolopyrrole (DPP) based D–A conjugated polymer could facilitate the p-doping and improve thermoelectric performance.
Abstract The scarcity of narrow bandgap donor polymers matched with perylene diimides (PDI)‐based nonfullerene acceptors (NFAs) hinders improvement the power conversion efficiency (PCE) value organic solar cells (OSCs). Here, it is reported that a polymer PDX, chlorinated derivative famous PTB7‐Th, blended PDI‐based NFA boosts PCE exceeding 10%. electroluminescent quantum PDX‐based OSCs two orders magnitude higher than PTB7‐Th‐based OSCs;therefore, nonradiative energy loss 0.103 eV lower....
