“…[1][2][3][4][5][6][7] Compared to the SMA-based PSCs, all polymer solar cells (all-PSCs), consisting of two conjugated polymers as both electron donor and electron acceptor, have more notable merits of excellent mechanical robustness, morphological stability, and suitable for flexible device fabrication. [8][9][10][11] Despite the numerous advantages of all-PSCs, much less attention has been devoted to all-PSCs, and only a few all-PSCs can yield PCEs over 15%, [12][13][14] which lags far behind the SMA-based PSCs. To boost the PCEs of all-PSCs, one of the most effective approaches is developing novel polymer acceptors.…”

“…To estimate the T g s of CPDT–ICMe and ZY-4Cl in the thin-film states, we used the temperature-dependent UV-vis absorption spectroscopy by following the procedure reported by Lipomi et al 75 This technique is very useful for determining the T g s of semi-crystalline materials in thin-film states that shows distinct light absorption behavior depending on temperatures. 35,76 As shown in Fig. 7a and c, the UV-vis absorption spectra of NFSMA films change with increasing temperature, owing to the rearrangement of amorphous domains and the formation of aggregates in semi-crystalline domains near their T g .…”

“…It is interesting to note that the morphology of the binary film has changed a lot but the ternary system maintains a smooth surface, which indicates that YF-CN may work as a stabilizer by suppressing aggregation and crystallization in the ternary blend. 73…”
