ABSTRACT:
A solar energy collector including a primary optical concentrator, one or more solar cells and an improved solar cell cover design is provided. Each of the solar cells includes a flexible cell cover which significantly reduces optical losses due to gridline obscuration of active cell area and also due to reflection from the cover itself. The cover comprises an optically clear, flexible material, such as a silicone polymer, placed over the illuminated surface of each solar cell, with prisms formed on the outer surface of the cover such that incident sunlight is refracted by the prisms onto active cell area rather than partially onto non-active gridlines or conducting elements. Each of the prisms has a predetermined shape depending on the type of primary optical concentrator used in the solar energy collector.
