The typical value of responsivity for high-efficiency concentrator solar cells is 0.395 A/W. If it varies with the concentration ratio, the solar cell is called sub-linear or super-linear. Therefore, a doped front side surface (T] or FSF) is usually reserved to low-concentration applications ( < 10 x).
