g-C3N4@TiO2 photoanodes for high-efficiency QDSSCs: improved electron transfer and photochemical stability

“…8 The advantages of simple preparation, multi-exciton effects, an adjustable light absorption range and environmental friendliness make QDSSCs the focus of current research and application. 7,9–13 In previous studies, researchers have continuously improved cell performance by optimizing the counter electrodes, 14 quantum dots 15 and electrolytes 16 of QDSSCs, which has increased their photoelectric conversion efficiency (PCE) value from less than 1% at the beginning to 16.1% 17–21 at present. Although significant progress has been made in the research of QDSSCs, there is still a large room for improvement in the distance from a theoretical PCE value of 44%.…”
