1. A solar photovoltaic blind slat, comprising:
a plurality of backplane supported solar cells having a light receiving frontside and a backside, each of said solar cell backsides attached to a slat core made of an electrically insulating prepreg material, said slat core forming an electrically insulating backplane for said backside of each of said plurality of solar cells, said light receiving frontside facing externally and said backside facing said slat core;
each of said solar cells partitioned into a plurality of sub-cells, said plurality of sub-cells scaling up the voltage and scaling down the current of each of said solar cells;
said slat core having at least a first side and a second side;
said solar cells attached on said first side and said second side;
each of said first side and said second side supporting a string of solar cells connected in series and a string of said sub-cells of each of said solar cells connected in series; and
a maximum-power-point tracking power optimizer component formed as a CMOS integrated circuit, embedded within said slat core, and corresponding to each of said plurality of solar cells.
