                 25.1%. It can be relatively easily produced by mass production because the metal contacts
                 applied to the rear side can be done without patterning.
                 BIFACIAL SOLAR CELLS
                 Bifacial solar cells have the capability to generate electricity by capturing light from both
                 sides. This may be useful in some applications [27]. Such cells, for example, are capable
                 of collecting diffused light from the back surface, thus increasing the total efficiency. One
                 variant of a simple bifacial cell structure is shown in Fig. 9.20.
