dc.description.abstract | Inorganic perovskite solar cells (PSCs) are considered prospective alternatives to organic PSCs due to their efficiency and relative stability. Cesium lead bromide (CsPbBr3) has a complete perovskite structure, is phase stable, exhibits a wide bandgap energy of 2.3 eV under operating conditions, and is regarded as a suitable material not only for stable PSCs, but also for semi-transparent PSCs. In this study, we synthesize Cu–Zn–In–S–Se (CZISSe) quantum dots (QDs) and demonstrate their novel use for improving the performance of PSC devices. QDs are embedded through ligand-exchange, which replaces long organic chains with thiosulfate (–S2O3) ligands and disperses the S2O3-capped QDs in the PbBr2 solution to prepare QD-blended precursor inks. The QDs promote the crystallization of CsPbBr3 and hole extraction from the photoactive layer. As a result, the optimized power conversion efficiency (PCE) of the QD-incorporated PSC is 5.37%, which is a 22.6% enhancement compared to those of the control devices. This work provides an effective and simple process for enhancing the performance of CsPbBr3-based PSCs. © 2020 The Korean Society of Industrial and Engineering Chemistry | - |
