A modified polysulfide redox couple, (CH(3))(4)NS/(CH(3))(4)NS(n), in an organic solvent (3-methoxypropionitrile) was employed in CdS quantum dot (QD)-sensitized solar cells (QDSSCs), and an unprecedented energy conversion efficiency of up to 3.2% was obtained under AM 1.5 G illumination. The QDs were linked to nanoporous TiO(2) via covalent bonds by using thioglycolic acid, and chemical bath deposition in an organic solvent was then used to prepare the QDSSCs, facilitating high wettability and superior penetration capability of the TiO(2) films. A very high fill factor of 0.89 was observed with the optimized QDSSCs.
一种改良的多硫化物氧化还原对，(CH(3))(4)NS/(CH(3))(4)NS(n)，在有机溶剂（3-甲氧基丙腈）中被用于 CdS 量子点（QD）敏化太阳能电池（QDSSCs）中，并在 AM 1.5 G 光照下获得了前所未有的 3.2%的能量转换效率。QD 通过硫代乙醇酸通过共价键与纳米多孔 TiO(2)相连，然后在有机溶剂中使用化学浴沉积来制备 QDSSCs，这有利于 TiO(2)薄膜的高润湿性和优异的穿透能力。优化后的 QDSSCs 的填充因子高达 0.89。
