N2 - A ternary mixture of carbon, copper sulfide, and cobalt sulfide was used to fabricate the counter electrode (CE) in quantum-dot-sensitized solar cells (QDSSCs). The ternary-mixture-based CE achieved much higher energy conversion efficiency than any CE based on the individual material. The mixture and the CE were investigated by photocurrent density-voltage characteristics, X-ray diffraction patterns, electrochemical impedance spectroscopy, and contour line plots. A balanced mix results in enhanced photocurrent and reduced charge transfer resistance at the interface, and this leads to optimized device performance. The highest photoelectric conversion efficiency was 3.73% at a 1:1:1 mass ratio. The efficiency was as high as 3.09% via a corresponding flexible CE.
