This study reports the characteristics of gel-type dye-sensitized solar cells (DSSCs), fabricated with gel-type electrolyte containing poly-1,1′-(methylenedi-4,1-phenylene)bismaleimide (PBMI), or poly-1,1′-(3,3′-dimethyl-1,1′-biphenyl-4,4′-diyl) bismaleimide (PDBBMI), or poly-N,N′-(4-methyl-1,3-phenylene)bismaleimide (PMPBMI), prepared by in situ polymerization of the corresponding monomer without an initiator at 30 °C. Incorporating 0.3 wt % content of exfoliated alkyl-modified nanomica (EAMNM) into PBMI-gelled electrolyte leads to higher short-circuit current density (Jsc = 17.14 mA cm-2) and efficiency (η = 7.02%) than that of neat PBMI-gel electrolyte (J sc = 15.32 mA cm-2, η = 6.41%). Incorporating 0.3 wt % EAMNM into PBMI-gelled electrolyte results in remarkably stable device performance under continuous light soaking under one sun (100 mW cm -2) at 55 °C. The efficiency of DSSCs based on PBMI/0.3 wt % EAMNM-gelled electrolyte drops by only 1.7% (η = 6.93%) after 500 h of continuous light soaking.
