Deskripsi
CaTi<sub>1−y</sub>Fe<sub>y</sub> O<sub>3−δ</sub> perovskite oxide films are promising candidate materials for p-type interlayers of third generation solar cells or light-emitting devices. The impact of atomic Ti substitutions by Fe on electrical and optical properties of CaTi<sub>0.5</sub>Fe<sub>0.5</sub>O<sub>3−δ</sub> perovskite films have been studied. The best compromise between a high transmission coefficient and the suitable electrical conductivity is obtained for a specific atomic composition of Ca (1) Ti (0.5) Fe (0.5) O (3−δ) perovskite films. This paper shows that CaTi<sub>1−y</sub>Fe<sub>y</sub>O<sub>3−δ</sub> perovskite oxides can be integrated as p-type interfacial layers of optoelectronic devices through their work functions, electrical, and optical properties.
