A PV module includes strings of serially electrically connected individual bifacial photovoltaic cells each of which is characterized by conversion efficiencies that are different for front and back sides of each cell. The module includes at least two of such strings which are electrically parallel to one another such that front sides of cells in one string and back sides of the cells in another string corresponding to the same side of the module. Each side of the module is thereby adapted to generate substantially the same amount of electrical power under otherwise equal circumstances. On a sunny day, the module generates as much electrical power before noon as after noon if the front side and the back side receive, aggregately, substantially the same amount of solar power incident thereon during the day. |
