Photoactive Properties of Transport Sol-Gel Layers Based on Strontium Titanate for Perovskite Solar Cells
In this work, we have investigated the photocurrent and spectral sensitivity of the silicon/SrTiO<sub>3</sub>:xNb/perovskite structures. The sol–gel method carried out the deposition of undoped SrTiO<sub>3</sub> layers as well as niobium-doped (SrTiO<sub>3</sub>:N...

| description | In this work, we have investigated the photocurrent and spectral sensitivity of the silicon/SrTiO<sub>3</sub>:xNb/perovskite structures. The sol–gel method carried out the deposition of undoped SrTiO<sub>3</sub> layers as well as niobium-doped (SrTiO<sub>3</sub>:Nb) layers at atomic concentrations of 3 and 6% Nb. The perovskite layer, CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3−x</sub>Cl<sub>x</sub>, has been deposited by the vacuum co-evaporation technique. The layers have been characterized by scanning electron microscopy and X-ray diffraction measurements. The volt–ampere characteristics and spectral sensitivity of the fabricated samples have been measured under illumination with selective wavelengths of 405, 450, 520, 660, 780, 808, 905, 980, and 1064 nm of laser diodes. We have shown that for different configurations of applied voltage between silicon, SrTiO<sub>3</sub>:xNb, and CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3−x</sub>Cl<sub>x</sub>, the structures are photosensitive ones with a variation of photocurrent from microamperes to milliamperes depending on Nb concentration in SrTiO<sub>3</sub>, and the highest photocurrent and spectral sensitivity values are observed when a SrTiO<sub>3</sub>:Nb layer with 3 at.% of Nb is used. A possible application of the proposed structure with a SrTiO<sub>3</sub>:Nb layer for perovskite solar cells and photodetectors is being discussed. |
