Efficiency of solar cells immersed in liquid dielectrics

An effect of the increase in the efficiency of solar cells (in particular, common silicon solar cells) is described when these solar cells are immersed in an isotropic liquid dielectric. The presence of a dielectric thin film results in an increase in the efficiency of solar cells by 40-60% from the reference value. The current-voltage characteristic, fill factor and other main parameters of these solar cells are analyzed. The mechanisms responsible for the increase in the efficiency of solar cells are discussed.
