Effects of alkali and transition metal-doped TiO(2) hole blocking layers on the perovskite solar cells obtained by a two-step sequential deposition method in air and under vacuum
Planar perovskite solar cells (PPSCs) have received great attention in recent years due to their intriguing properties, which make them a good choice for photovoltaic applications. In this work, the effect of alkali and transition metal-doped TiO(2) (cesium-doped TiO(2) (Cs-TiO(2)) and yttrium-doped...

description | Planar perovskite solar cells (PPSCs) have received great attention in recent years due to their intriguing properties, which make them a good choice for photovoltaic applications. In this work, the effect of alkali and transition metal-doped TiO(2) (cesium-doped TiO(2) (Cs-TiO(2)) and yttrium-doped TiO(2) (Y-TiO(2))) compact layers on the optical, structural and the photovoltaic performance of the PPSCs have been investigated. The perovskite layer syntheses were carried out by depositing a lead iodide (PbI(2)) layer via spin-coating; converting PbI(2) into methyl ammonium iodide (CH(3)NH(3)PbI(3)) by chemical vapor deposition (CVD) and spin-coating at 60 min and 60 s conversion times respectively. The as-deposited PPSCs were studied layer-by-layer using an X-ray diffractometer, scanning electron microscope, and UV-vis diffuse reflectance, transmittance and absorbance. The power conversion efficiency for stable processed perovskite solar cells were 3.61% and 12.89% for air and vacuum processed, respectively. |
