dc.description.abstract | A novel multifunctional polymer ionic liquid poly(oxyethylene)-imide-2,2,6,6-tetramethyl-1-piperidinyloxy (POEI-TEMPO) was successfully prepared and used as an additive in iodide electrolyte in quasi-solid-state dye-sensitized solar cells (QSS-DSSCs). The POEI segment in the electrolyte has good mechanical strength; meanwhile, the TEMPO organic radical contains nitroxide as the redox couple (RN-O˙/RNO+) acting as a superior mediator in DSSCs. TEMPO has a number of favorable properties, such as fast and reversible redox kinetics, large apparent diffusion coefficient (Dapp), positive redox potential, and facile electron self-exchange reaction. As a result, DSSCs were composed of aPOEI-TEMPO/iodide electrolyte and a Pt-coated FTO layer on glass as a normal counter electrode (PtCE), whereas the other side of the glass was coated with silver mirror coating (SMC) as the bifacial PtCE/SMC cell. DSSC exhibited a maximum photoelectric conversion efficiency (η) of 9.83%, open-circuit voltage (VOC) of 812.84 mV, and short-circuit current density (JSC) of 16.60 mA cm?2under 1 sun (AM 1.5 G, 100 mW cm?2), whereas the value ofηreached 25.99% under an indoor condition with 6000 lux (1.89 mW cm?2). Moreover, whenPOEI-TEMPOis used as an additive, the bifacial cell maintains its high performance with a reasonable long-term stability. The finding is expected to have a practical impact on harvesting the ambient light energy and extending the cell lifetime. ? The Royal Society of Chemistry 2021. | - |
