Abstract
Bifacial crystalline solar cells and associated solar panel systems are provided. The include a p-type crystalline silicon layer and a barrier layer. The panels include at least two rows of cells. The cells in each row are connected to one another in series. The rows are connected in parallel. A reflector is used to reflect light towards the underside of the panel. A long axis of the reflector is arranged to be parallel to the rows of cells.
Claims8
