In the context of technology, “SnS interface” could refer to several different things depending on the specific field or application. Solar cells will be crucial in the world's transition to renewable energy as the quest for carbon neutrality grows and as a concerning pattern of rising temperatures and natural disasters brought on by global warming continues. Now, a research group has laid the path for achieving higher open-circuit voltage in tin sulfide (SnS) solar cells, thus realizing their latent potential as a thin-film solar material. Compound semiconductors with high light absorption that are used in thin-film solar cells make them
