The vinylene-bridged helical perylene diimide (PDI) dimer (PDI2) with a build-in twisted configuration is an alternative building block to the parent PDI for construction of efficient non-fullerene acceptor (NFAs). Moreover, it has been proved asymmetric strategy plays vital role in development NFAs. Herein, we designed and synthesized pair acceptor-donor-acceptor (A-D-A) type PDI2 derivatives, namely IDTIC-PDI IDT-diPDI2, which contain symmetric end-cap units, respectively. To determine structure-performance relationships strategy, organic solar cells (OSCs) based on these two molecules were fabricated measured. device exhibits much higher PCE 8.23 % than that IDT-diPDI2 (5.21 %). These results reveal symmetry breaking provides effective way optimize photovoltaic performances OSCs.

Abstract With the advances in organic photovoltaics (OPVs), development of low‐cost and easily accessible polymer donors is vital importance for OPV commercialization. Polythiophene (PT) its derivatives stand out as most promising members photovoltaic material family commercial applications, owing to their low cost high scalability synthesis. In recent years, PTs, paired with nonfullerene acceptors, have progressed rapidly performance. This Review gives an overview strategies designing PTs OPVs from perspective energy level modulation. A survey typical classes acceptors designed pairing benchmark PT, i.e., poly(3‐hexylthiophene) (P3HT) also presented. Furthermore, achievements understanding controlling film morphology PT:nonfullerene blends are discussed depth. addition effects molecular weight blend ratio on morphology, crucial roles miscibility between PT processing solvent determining microstructure highlighted, followed by a discussion thermal annealing ternary active layers. Finally, remaining questions prospects systems outlined. It hoped that this review can guide optimization advance applications.

Abstract Integrating a third component into the binary system is considered to be one of most effective strategies further enhance power conversion efficiency (PCE) in organic solar cells (OSCs). Here, novel perylene diimide (PDI) derivative featuring 3D structure, TPA‐4PDI, with tetraphenyladamantane central core developed as guest electron acceptor incorporated PM6:Y6 system. The champion PCE ternary OSC recorded 18.29% by adding 7.5 wt.% TPA‐4PDI blend, which photovoltaic performance enhanced synergistically increased open‐circuit voltage ( V oc ) 0.849 V, short‐circuit current density J sc 27.55 mA cm −2 , and fill factor (FF) 78.21%. exhibits complementary absorption band PM6 Y6 while its lowest unoccupied molecular orbital (LUMO) energy level falls between two host materials. addition can effectively suppress recombination behavior, inhibit excessive aggregation improve morphology blend. All these effects function then lead enhancement oc, FF OSCs. This study suggests that developing PDI derivatives an method

Abstract With the rapid development of non‐fullerene acceptors (NFAs), power conversion efficiency (PCE) organic solar cells (OSCs) is increasing. According to their different chemical structures, NFAs can initially be divided into two categories: small molecule (SMAs) and polymerized (PSMAs). Due strong absorption capacity controllable energy levels, PCE devices based on SMAs has approached 20 %. Compared with SMAs, PSMAs have advantages in stability flexibility, PSMA‐based exceeded 18 However, higher synthesis cost lower batch repeatability hinder its further development. Recently, concept giant (GMAs) been proposed. These materials a clear molecular structure are considered novel acceptor that combine PSMAs. Currently, GMAs 19 In this review, we will introduce latest developments PSMAs, GMAs. Then, relationship between performance analyzed. end, perspectives opportunities challenges these provided, which could inspire for advanced OSCs.
