The escape cone forms two pairs of symmetrical cones for emission angles smaller than the critical angle. Absorption serves as an ambivalent role. On one hand, high absorption effectively captures more light and transforms it into the desired range. On the other hand, it can result in undesirable high re-absorption rates.

High-efficiency concentrator silicon solar cells
The typical value of responsivity for high-efficiency concentrator solar cells is 0.3 9 5 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 (TJ or FSF) is usually reserved to low-concentration applications ( < 10 x).
