NOVELTY - The assembly has an electrically insulating layer that is positioned between an electric-optically transducing layer and an electrically conducting layer. A dielectric layer is positioned between the electrically conducting layer and a hydrophobic layer. A digital microfluidic lens (10) is positioned in contact with the hydrophobic layer. The electrically conducting layer, the hydrophobic layer and the dielectric layer are optically transparent.    USE - Thin film silicon solar cell assembly. Uses include but are not limited to solar power plant, solar airplane, submarine, vehicle, mobile solar charger military, army and commercial applications.    ADVANTAGE - The incorporation of electro wetting on dielectric (EWOD) digital microfluidic lenses into solar cell assemblies increases the light throughput by increasing the effective acceptance angle and the efficiency of the power conversion. The power generation can be increased by enhancing the light absorption in a wide acceptance angle provided by an electro wetting lenses and/or by reducing the light losses. Solar thermal energy harvesting can be directly enhanced by enabling the fully controllable embedded optical throughput interface to maximize power generation. The thickness of the thin film solar cells is made small so that the optical absorption inside the silicon layers can be enhanced by increasing the optical throughput of solar radiation. The cost of controllable solar cell assembly can be reduced while efficiency is maximized by utilizing the light throughput control units. Since the operating temperature of the cell assembly is controlled from the surface, the lifetime of the cell can be significantly increased. The need for a sunlight-tracking system and expensive equipment to maintain cell assemblies and multiple cell arrays facing toward the sun is reduced. The amount of electric current and voltage can be controlled to maximize the output power of the cell and decrease the complexity of the control system.
