Stable and highly efficient PbS quantum dot tandem solar cells employing a rationally designed recombination layer. Shi G, Wang Y, Liu Z, Han L, Liu J, Wang Y, Lu K, Chen S, Ling X, Li Y. Near-infrared emission Photovoltaic material Sb2S3 Water-soluble quantum dot. The E g of Sb 2S 3 QD thin film has been found to be tunable from 1.82 to 1.09 eV via annealing or selenylation, demonstrating the good prospects in photovoltaic application. Their band gaps (E g s) were calculated according to transmittance spectra. Sb 2S 3 QD thin films were prepared by self-assembly growth and then annealed in argon or selenium vapor. An intensive PL emission at 880 nm was found, indicating Sb 2S 3 QDs have good prospects in near-infrared LED and near-infrared laser application. Photoelectric properties including absorbing and emission were characterized by UV-Vis-IR spectrophotometer and photoluminescence (PL) spectroscopic technique. To fill this vacancy, water-soluble Sb 2S 3 QDs were prepared by hot injection using hexadecyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS) mixture as anionic-cationic surfactant, alkanol amide (DEA) as stabilizer, and ethylenediaminetetraacetic acid (EDTA) as dispersant. However, there was lack of information about Sb 2S 3 quantum dots (QDs) because of the synthesis difficulties. Antimony sulfide (Sb 2S 3) has been applied in photoelectric devices for a long time.
