Abstract

Morphology plays a major role in the performance of solar cells based on solution-processed perovskite solid-state thin films. The growth of perovskite films on substrates without defects and grain boundaries is equally important for attaining high power conversion efficiencies (PCEs). Herein, we have adapted a mixed solvent engineering to make high quality perovskite solid-state thin films for solar cell applications. The spin coated perovskite films have been systematically characterized via UV-visible absorption, field emission scanning electron microscopy (FESEM) and one-dimensional (1-D) X-ray diffraction (XRD) tools. Current density-voltage (JV) measurement was carried out to characterize the fabricated solar cell devices. The perovskite solar cell fabricated with optimized mixed solvent engineering exhibited high photocurrent (22.4 mA/cm2) and PCE of 15.2%.
