摘要: Abstract We present a new photosensitizer – Ag 2 S quantum dots (QDs) for solar cells. The QDs were grown by the successive ionic layer adsorption and reaction deposition method. assembled S-QD cells yield best power conversion efficiency of 1.70% short-circuit current 1.54 mA/cm under 10.8% sun. have maximal external (EQE) 50% at λ = 530 nm an average EQE ∼ 42% over spectral range 400–1000 nm. effective photovoltaic covers visible near-infrared regions is ∼ 2–4 times broader than that cadmium chalcogenide systems — CdS CdSe. results show can be used as highly efficient broadband sensitizer
