THIN FILM SOLAR CELL HAVING TIN SULFIDE LIGHT-ABSORBER LAYER AND METHOD OF MANUFACTURING THE THIN FILM SOLAR CELL

摘要

A thin film solar cell is disclosed. The thin film solar cell includes a first electrode and a second electrode disposed to face each other; a light absorption layer disposed between the first electrode and the second electrode and formed of tin sulfide (SnS); a first buffer layer disposed between the light absorption layer and the first electrode and forming a p-n junction in contact with the light absorption layer; and a second buffer layer disposed between the first buffer layer and the first electrode and formed of zinc-magnesium oxide including a crystalline zinc oxide phase and an amorphous magnesium oxide phase.
