The effects of electrolyte additives on the cell performances of CdS/CdSe quantum dot sensitized solar cells
The electrolyte for QDSSCs is normally a polysulfide, S2-/Sx2-, redox couple. This couple plays an important role for the regeneration of quantum dots. This study examined the effects of the electrolyte for CdS/CdSe QDSSCs. Electrolytes consisting of 1M Na2S, 2M S in a methanol and water-mixed solution at a 7 : 3 ratio with or without additives such as KCl, NaOH, KOH and NaCl were used for QDSSC. The electrolyte with NaOH showed the highest conversion efficiency, 3.18%. The reasons for the improved photovoltaic characteristics were analyzed using a range of techniques.
