Abstract

The field of photovoltaic research is witnessing significant growth in the study of organic-inorganic perovskites, primarily due to their promising optoelectronic properties and the notable increase in their power conversion efficiency (PCE). Despite the advantageous characteristics exhibited by lead halide-based perovskites, such as their suitability as absorbers, the issue of instability remains a prominent concern. To address this challenge, we propose a potential solution involving the partial doping of all-inorganic perovskite CsPbI3 quantum dots (PQDs) with bromine. This approach not only aims to mitigate the instability problem but also allows for the customization of the band gap of pure cesium lead bromide CsPbBr3. Furthermore, we explore the impact of solvent selection and the choice of precipitating agent on the stability of the resulting quantum dots. Through the implementation of a hot injection method, we successfully synthesized perovskite quantum dots (PQDs) and conducted an analysis of their optical, structural, and thermal properties. X-ray diffraction analysis revealed the cubic phase of the prepared mixed halide CsPbI3-xBrx PQDs.
