Recently, there have been notable advancements in perovskite solar cells (PSCs), especially those incorporating organic�inorganic lead halides, leading to an impressive efficiency milestone of 25.20%. Nevertheless, the enduring problem of lead toxicity represents a substantial hurdle to their broad commercial utilization. In response to this chall...

In the current study, the sol-gel spin coating was used to deposit SnS thin films on ordinary glass substrates, and annealed without sulfurization at 500 °C. Different organic solvents such as ethanol, 2-methoxyethanol, and methanol were used and their influence on the properties of SnS thin films was investigated. X-ray diffraction showed that the...

In this work, the SnS thin film was deposited on the glass substrate by spray technique at 350 °C.
