Low-Temperature and Rapid Deposition of an SnO2 Layer from a Colloidal Nanoparticle Dispersion for Use in Planar Perovskite Solar Cells

Original language description

Deposition of the electron transport layer (ETL) is an important step in the manufacture of low-cost, solution-processed perovskite solar cells (PSCs). Thermal annealing processes account for a major part of the energy consumption involved in the fabrication of PSCs. The current paper presents a plasma-based and highly convenient method (5 min, <60 degrees C) for the deposition of SnO2 films (PT-SnO2) from a colloidal nanoparticle dispersion. A comparative evaluation of PT-SnO2 films with those created by state-of-the-art thermal annealing (30 min, 180 degrees C) (TA-SnO2) is made herein. The key mechanism in the formation of the SnO2 layer is explained in relation to the evaporation of the dispersion medium. This comparison of PT-SnO2 and TA-SnO2 indicates a considerable difference in terms of energy consumption directly relevant to the low-cost manufacture of PSCs. Photoluminescence analysis revealed no particular differences in the charge extraction of the two types of SnO2 films. The SnO2 films were subsequently employed as an ETL in planar n-i-p PSCs. Results revealed that the PSC resulting from PT-SnO2 yielded an efficiency of 15.17%, similar to that of 15.91% corresponding to TA-SnO2. In addition, the PSC fabricated on the PT-SnO2 maintaining approximate to 80% of its initial performance after 21 days in ambient conditions.
