The key was bending the light the optimal amount, enough that it enters the solar panel at an angle, but not so much of an angle that the light reflects off and is lost.
The bendingAngle increases with an increase of the energy density.
增加能量密度,板料的弯曲角度显著增大。

The results show that: the springback Angleof bent tube increases with the bendingAngle, the gap between mandrel and tube, and the hardening coefficient, but decreases with the hardenability value.
