One-step synthesis of SiO2 nanomesh for antireflection and self-cleaning of solar cell

SiO 2 nanomaterials are widely used for antireflection and self-cleaning, but the preparation process is usually complex and time-consuming. Hence, we present a facile one-step synthesis of a hydrophobic two-dimensional SiO 2 nanomesh by tuning the reaction temperature using dodecylamine as a catalyst. SiO 2 nanomesh has the advantages of an adjustable refractive index , simple preparation process, and low cost, which affords both antireflection and self-cleaning functions for solar cells. Two types of perovskite solar cells were used to verify the stability and universality of the SiO 2 nanomesh coatings. The antireflection effect of the SiO 2 nanomesh is found to increase the current density of both perovskite solar cells fabricated at 500 °C and 150 °C, with the efficiency increased by 4.48% and 4.79%, respectively.
