    摘要: A method for fabricating a photovoltaic device includes forming a film including titanium on a conductive layer formed on a substrate. An absorber layer is formed including a Cu—Zn—Sn containing chalcogenide compound with a kesterite structure of the formula: Cu2-xZn1+ySn(S1-zSez)4+q wherein 0≦x≦1; 0≦y≦1; 0≦z≦1; −1≦q≦1 (CZTS) on the film. The absorber layer is annealed to diffuse titanium therein and to recrystallize the CZTS material of the film. A buffer layer is formed on the absorber layer, and a transparent conductive layer is formed on the buffer layer.
