“…The boron–nitrogen coordination bonds (B←N) in PBN‐10 facilitate a medium bandgap with tunable LUMO and HOMO energy levels, resulting in a high V OC of 1.14 V and an average PCE of 25.2% under FL at 1000 lx . [ 49 ] Cui et al. fabricated an organic photovoltaics with a wide‐bandgap NFA ITCC and donor polymer PM6 in order to maximize the overlap between the absorption spectra of the device with the emission spectrum of the indoor light source while still maintaining a high V OC .…”

Organic solar cells (OSCs) based on nonfullerene acceptors (NFAs) have made significant breakthrough in their device performance, now achieving a power conversion efficiency of ≈18% for single junction devices, driven by the rapid development in their molecular design and device engineering in recent years. However, achieving long‐term stability remains a major challenge to overcome for their commercialization, due in large part to the current lack of understanding of their degradation mechanisms as well as the design rules for enhancing their stability. In this review, the recent progress in understanding the degradation mechanisms and enhancing the stability of high performance NFA‐based OSCs is a specific focus. First, an overview of the recent advances in the molecular design and device engineering of several classes of high performance NFA‐based OSCs for various targeted applications is provided, before presenting a critical review of the different degradation mechanisms identified through photochemical‐, photo‐, and morphological degradation pathways. Potential strategies to address these degradation mechanisms for further stability enhancement, from molecular design, interfacial engineering, and morphology control perspectives, are also discussed. Finally, an outlook is given highlighting the remaining key challenges toward achieving the long‐term stability of NFA‐OSCs.

“…The authors introduced a new class of polymer acceptors containing boron-nitrogen coordination bonds (B ) N), which possess suitable bandgaps with tuneable LUMO and HOMO energy levels. 30 In particular, the polymer acceptor PBN-10 (which has a bandgap of 1.95 eV) in blend with the polymer donor CD1 (which has a bandgap of 1.93 eV) as the active layer exhibits a PCE of 26.2% under FL illumination at 1000 lx with a high V oc value of 1.14 V ( Fig. 1c and Table 3).…”

Benzodithiophene‐S,S‐tetraoxide (BDTT) as an Acceptor Towards Donor‐Acceptor (D‐A)‐Type Semiconducting Electropolymers

This study introduces a benzodithiophene-S,S-tetraoxide (BDTT) monomer as an acceptor and 3,4-ethylenedioxythiophene flanked thiophene (TEDOT 2) and terthiophene (T 3) as donor molecules for polymer formation. The synthesis of the poly (TEDOT 2-BDTT) and poly(T 3-BDTT) copolymers was performed via a single-step monomer radical formation that is typically associated with electropolymerization methods. The electropolymerization is controlled by using a suitable monomer stoichiometric ratio that enables the deposition of copolymer thin films on the working electrode. Resultant copolymers were investigated by electrochemical analysis and their electronic properties are discussed in detail. A low average electron transport resistance of 16.5 Ω was found for poly(TEDOT 2-BDTT), indicating excellent conductive behavior. Solid-state absorbance and emission studies of the copolymers show visible to near-infrared spectral activity. Results support an effective strategy towards highly efficient electronically conducting polymers (ECPs) based on a unique BDTT monomer.
