However, there are concerns regarding the use of lead (Pb) in traditional PSCs, particularly its potential impact on the environment and human health. Consequently, the advancement of lead-free perovskite solar cells is of utmost importance to safeguard both the environment and human well-being. Tin-based perovskites present a promising alternative to lead-based PSCs. Tin (Sn) has shown promising optoelectronic properties and can be used as a substitute for lead. However, there are obstacles associated with the weak stability of Sn<sup>2+</sup> ions that must be overcome in order to develop tin-based PSCs that are both extremely stable and efficient. This review specifically examines the progress made within the field of lead free tin-based perovskite solar cells, with a particular focus on stability and efficiency. The discussion delves into the effect of various cations and their compositions on the devices' stability. It is important to mention that devices based on tin halide perovskites have achieved an unexpectedly high level of efficiency in a short amount of time.

The applications of CDs, which are generally smaller than 10 nm, in myriad fields are ascribed to their intrinsic merits of good biocompatibility, little cytotoxicity, good stability, and large specific surface area. The development of CDs along with their accurate characterization, and their successful implementation into faster, less expensive, and more reliable systems in a variety of scientific fields are testimony to how science has advanced and merged to create interdisciplinary fields. Despite extensive research, there is still the need to overcome the problem of large-scale production and improve quantum yield as well as functionality for specific applications, which this study seeks to analyze.
