Query: Enhancement of perovskite solar cells by plasmonic nanoparticles   Synthetic perovskites with photovoltaic properties open a new era in solar
photovoltaics. Due to high optical absorption perovskite-based thin-film solar
cells are usually considered as fully absorbing solar radiation on condition of
ideal blooming. However, is it really so? The analysis of the literature data
has shown that the absorbance of all photovoltaic pervoskites has the spectral
hole at infrared frequencies where the solar radiation spectrum has a small
local peak. This absorption dip results in the decrease of the optical
efficiency of thin-film pervoskite solar cells by nearly 3% and close the ways
of utilise them at this range for any other applications. In our work we show
that to cure this shortage is possible complementing the basic structure by an
inexpensive plasmonic array.
