Highly Compact TiO<sub>2</sub> Films by Spray Pyrolysis and Application in Perovskite Solar Cells
Abstract
<jats:sec><jats:label /><jats:p>Transparent and pinhole free hole‐blocking layers such as TiO<jats:sub>2</jats:sub> grown at low temperatures and by scalable processes are necessary to reduce production costs and thus enabling commercialization of perovskite solar cells. Here, the authors compare the transport properties of TiO<jats:sub>2</jats:sub> compact layers grown by spray pyrolysis from commonly used titanium diisopropoxide bisacetylacetonate ([Ti(OPr<jats:sup>i</jats:sup>)<jats:sub>2</jats:sub>(acac)<jats:sub>2</jats:sub>]) precursor to films grown by spray pyrolysis of TiCl<jats:sub>4</jats:sub>. Spray pyrolysis provides insights into the interdependence of precursor chemistry and electron transport properties of TiO<jats:sub>2</jats:sub> films and their influence on the performance of the perovskite solar cells. X‐ray diffraction and X‐ray photoelectron spectroscopy data confirm the chemical and structural composition of the obtained films. Thin film deposition at lower temperature (150 °C) are conducted using TiCl<jats:sub>4</jats:sub> to evaluate the influence of crystal growth and topography by scanning electron microscopy and atomic force microscopy as well as thickness (profilometry) and transmittance (UV/Vis spectroscopy) on the power conversion efficiency of perovskite solar cells. TiO<jats:sub>2</jats:sub> compact layers grown from TiCl<jats:sub>4</jats:sub> enhance the power conversion efficiency by acting as superior electron transfer medium and by reducing hysteresis behavior, when compared to films grown using titanium diisopropoxide bisacetylacetonate. UV/Vis spectroscopy and external quantum efficiency studies reveal the correlation of transmittance on the power conversion efficiency.</jats:p></jats:sec>
