Effect of ball milling time on Sr_0.7Sm_0.3Fe_0.4Co_0.6O_2.65 perovskites and their application as semiconductor layers in dye-sensitized solar cells.

ABSTRACT: The practical utilization of TiO₂ as a semiconductor in dye-sensitized solar cells (DSSCs) has been set back by poor visible light absorption, high charge carrier recombination, and low electrical conductivity, which reduce the power conversion efficiency (PCE) and sustainability of the device. In this respect, perovskites with excellent properties, such as large surface area, good optical properties, high electrical conductivity, and superior electrochemical stability, have recently emerged as promising alternatives capable of overcoming the drawbacks of TiO₂. Herein, Sr_0.7Sm_0.3Fe_0.4Co_0.6O_2.65 (SSFC) perovskites were prepared via the ball milling method at various milling times of 0, 5, and 10 h, and the obtained
