(JP11243225-A)   NOVELTY - The photovoltaic module has a number of concentrators (17-1,17-2,17-3,..) each having an incidence plane (1) and a reflection plane (2) and photodetectors (5) in contact with respective concentrators. Each concentrator has a different effect on incident light angled to the right of the surface normal and incident light angled to the left of the surface normal.    USE - The photovoltaic module is used as a roof tile for generating electricity from incident solar radiation.    ADVANTAGE - The photovoltaic module is designed for converting sunlight into electrical energy throughout the year.
