SnS is expected to be a promising material for solar cells because it contains no toxic or rare elements and has an optimal band gap for solar cells. The authors previously made SnS homojunctions by sputtering p-type SnS polycrystals on Cl-doped n-type SnS single crystals, but the short-circuit current density (Jsc) was as low as 7.5 mAcm^-2. To enhance Jsc, high-quality p-type SnS films were deposited by the liquid phase epitaxy. As a result, the Jsc was improved to 15 mAcm^-2.
