dc.description.abstract | High-molecular-weight electro-active polymer acceptor (PA) is effective in simultaneously increasing photovoltaic performance and mechanical integrity of polymer solar cells (PSCs) based on a polymer donor (PD) and a small molecule acceptor (SMA). In this work, we develop a new naphthalene diimide (NDI)-based PA, named P(NDI2OD-TCVT), and employ it as a PA additive in a PD:SMA blend to fabricate high-performance and mechanically robust PSCs. Copolymerization of NDI, bithiophene, and cyano-vinylene units ensures the n-type characteristics of the P(NDI2OD-TCVT). Noticeably, regio-random attachment of the cyano-vinylene group alleviates the crystalline nature of the NDI-based polymer, providing inter-domain bridges by being a tie molecule. As we vary the weight-average molecular weight (Mw) of the polymer, we find that the backbone structure enables a significant reduction of the critical molecular weight that ensures mechanical robustness. High crack-onset strain (COS) of 30.1% is achieved in the P(NDI2OD-TCVT) film with a relatively low Mw of 109 kg mol-1, which is a stark contrast to the COS value (1.1%) of the reference P(NDI2OD-T2) film with similar Mw of 126 kg mol-1. In addition, we find that incorporation of P(NDI2OD-TCVT) enhances the photovoltaic performance of the PD:SMA-based PSCs, achieving a high power conversion efficiency (PCE) of 16.9%. Benefitted from the significantly enhanced mechanical properties of P(NDI2OD-TCVT), we also demonstrate the highly efficient and intrinsically stretchable polymer solar cells (IS-PSCs). The IS-PSCs with 10 wt% of P(NDI2OD-TCVT) featured a PCE of 12.6% and retained 85% of the initial PCE after 100 cycles of stretching at 20% strain and releasing, outperforming those of P(NDI2OD-T2)-based IS-PSCs. We develop a mechanically-ductile naphthalene diimide-based polymer, named P(NDI2OD-TCVT). We demonstrate its viability to achieve intrinsically-stretchable polymer solar cells with a high power conversion efficiency and mechanical stretchability. | - |
