The study introduces a cobalt-based, jellified aqueous electrolyte with xanthan gum, which achieves an efficiency exceeding 4% in DSSCs. Using design of experiment, the effects of Co2+ concentration, Co2+/Co3+ ratio, and xanthan gum amount modifications on the photovoltaic parameters of lab-scale solar cells were precisely and significantly studied.
Aqueous dye-sensitized solar cells (DSSCs) are emerging as a promising alternative to enhance both the lifetime and environmental friendliness of traditional DSSCs. Herein, a cobalt-based, jellified (with xanthan gum) aqueous electrolyte, leading to a valuable efficiency exceeding 4% (V-OC = 847 mV, J(SC) = 6.73 mA cm(-2), fill factor = 74%), is reported. Design of experiment is used to precisely and significantly study, at a multivariate level, the effects produced by the Co2+ concentration, Co2+/Co3+ ratio, and xanthan gum amount modifications on the overall photovoltaic parameters of lab-scale solar cells.
