Abstract

Among the functional materials suitable for the realization of solar cells and light emission diodes (LEDs), perovskites, especially fully inorganic perovskites, are considered among the most promising. CsPbBr3 is the most studied due to its favorable band gap value and stability under mild atmospheric conditions: moisture and UV visible radiation exposure. Using this material, highly efficient thin film solar cells have been produced at the lab scale, and researchers aim to scale the process up to the industrial level. Here, ultrathin films of CsPbBr3 were obtained by magnetron sputtering, and the texture and morphology of the deposited films were evaluated as a function of their thickness and the substrate's nature. The obtained films are composed of highly textured structures of submicrometric crystals homogeneously distributed all over the surface. Finally, the texture decreases as the deposit thickness increases.
