摘要：
In this work we have studied coverage characteristics of organo -metal lead halide perovskite thin films deposited through the spin-coating technique onto glass substrates that were subjected to different pre-deposition treatments. Samples were deposited at room temperature using different spinning speeds and two different solvents, namely, dimethylformamide (DMF) and gamma-butyrolactone (GBL). In this way we obtained samples with different characteristics. Characterization of substrate coverage was performed through optical microscopy and we have also performed optical characterization of the deposited films through transmittance measurements. All obtained samples were highly polycrystalline as evidenced from X-ray diffraction measurements.
