Improving the Efficiency of Perovskite Solar Cell through the Addition of Compact Layer under TiO<sub>2</sub> Electron Transfer Material
Abstract
<jats:p>In the fabrication of perovskite solar cells, the perovskite layer is typically deposited onto the TiO<jats:sub>2</jats:sub> semiconductor layer. The TiO<jats:sub>2</jats:sub> layer serves as an electron transport material (ETM). In order to form the perovskite layer firmly and evenly, a structured mesoporous (MS) TiO<jats:sub>2 </jats:sub>surface is required. A porous layer could also make the electrons move more quickly through the pores to reach the contact. However, the electron-hole recombination and electron trapping in the dead end pore are still occurred. One of the solutions to overcome this problem is to add a thin compact layer (CL)-TiO<jats:sub>2</jats:sub> under MS-TiO<jats:sub>2</jats:sub> layer. The CL-TiO<jats:sub>2</jats:sub> is expected as to prevent recombination and attract electrons trapped in the MS-TiO<jats:sub>2</jats:sub> layer. In this paper, we report the addition of a thin compact layer (CL)-TiO<jats:sub>2</jats:sub> under MS-TiO<jats:sub>2</jats:sub> layer in the fabrication of perovskite solar cells based on methyl ammonium lead iodide (CH<jats:sub>3</jats:sub>NH<jats:sub>3</jats:sub>PbI<jats:sub>3</jats:sub>). The compact layer TiO<jats:sub>2</jats:sub> was grown under mesoporous TiO<jats:sub>2</jats:sub> layer by dip-coating in TiCl<jats:sub>4</jats:sub> solution. The time of the dip coating was varied to obtain an optimum efficiency improvement. The structure of the device is glass/FTO/CL-TiO<jats:sub>2</jats:sub>/MS-TiO<jats:sub>2</jats:sub>/ CH<jats:sub>3</jats:sub>NH<jats:sub>3</jats:sub>PbI<jats:sub>3</jats:sub>/Spiro-OMeTAD/Ag/FTO/glass. It was concluded that the addition of CL-TiO<jats:sub>2</jats:sub> can improve the perovskite solar cells power conversion efficiencies. The best efficiency was obtained from the 15 minutes dip-coating, which corresponded to the thinnest CL-TiO<jats:sub>2</jats:sub> out of all samples. The electrical characterization performed under irradiation with an intensity of 50 mW/cm<jats:sup>2</jats:sup> at 25 °C generated an open circuit voltage of 0.28 V, a short circuit current density of 0.25 mA/cm<jats:sup>2</jats:sup> and a power conversion efficiency of 0.60 %.</jats:p>
