Solar cells lose high percent of their capacity as a result of insufficient solar radiation, due to changing of the solar angle of projection during the day. Thus this research aims to increase the cell efficiency by a novel method which is based on collecting rays in the convex focus and dispersed in the concave lens, to make the rays always perpendicular on cells. To achieve this purpose, glass balls with a diameter of 10 mm were used and arranged on the cell area. This work found an obvious increasing in the cell efficiency, where it is possible to have an increasing in generating voltage by an estimated 7.53%, and the current 1.086% by this novel method.
