Metal-based semiconductor nanomaterials for thin-film solar cells 181

1D nanostructures needs to be increased, and (c) interface/electrode engineering and
electron transport through the ETMs in PSCs/OSCs need further study. In addition,
in recent years a wearable, portable, and foldable design has gradually become one
of the trends for the development of electronic products. However, high-temperature
annealing is widely used to obtain high-quality crystalline semiconductive electrodes.
Thus a major challenge to moving thin-film solar cells toward flexible application is the
limitation that temperature imposes on plastic substrates. Therefore developing low-
temperature fabricated devices would represent a promising trend.
