Effect of liquid dielectrics on the efficiency of silicon solar cells

The results of experimental studies of the change in the photoelectric characteristics of silicon solar cells produced as a result of depositing thin, liquid dielectric layers (glycerine, acetone, isopropyl alcohol, butanol, dioxane, deionized water) are presented. It is shown that the presence of these liquids reduces the forward and reverse currents, substantially raises the short-circuit currents and open-circuit voltage, and significantly increases the efficiency (by up to 40–60%). Possible physical models are proposed for this effect.
