Simulation of plano-convex cylindrical lens effects on photovoltaic solar cells efficiency

摘要

A method for control and modification of solar cell efficiency using a plano-convex cylindrical lens is proposed. Optical effects of a plano-convex cylindrical lens placed on a solar cell are detailed theoretically and numerical simulations are used to modify the efficiency of the cell. It was found that the lens could reduce the incident angle of the beam and enhance the solar cell voltage. The output power from the solar cell could be controlled using this lens during the day and a modification method is proposed in order to gain more output power from a solar cell. This method is a low cost and green method to gain controllable output voltage from the photovoltaic solar cells. Experiments confirm the effectiveness of this method.
