Optimization of Optical Performance and Dust Removal Efficiency of Electrodynamic Screen (EDS) Films for Improving Energy-Yield of Solar Collectors

Abstract

Silver nanowire (AgNW) electrodes of the Electrodynamic Screen (EDS) aim at restoring the output power lost due to soiling and ensure minimal loss in transmission efficiency when retrofitted on the PV modules. Experiments are done to improve the robustness of electrodes by incorporating zinc oxide (ZnO) layers in electrode structure. Alternatively, the use of a protective clear polymer overcoat over the entire design aims to increase the stability and durability of the silver nanowires in the electrodes. Hybrid ink is also developed by using silver nanospheres to increase conductivity of electrodes. New designs of electrode geometry and structure to increase efficiency of EDS operation are discussed.
