Effect of photovoltaic characteristics under 40 mm and 32 mm bend radius are revealed. Performances were compared to the measurements in a planar state before and after bending test. The impact of bending test on EQE, C-V and residual stress measurements were analysed.

How big a PV panel should be under bending?

Since the width of the two steel beams and the frame cannot be ignored in that modi ed frame structure, the actual size of the PV panel fi under bending should be 1488 855 7.4 (unit: mm). And the later calculation and simulation should choose that size value.

Does bend radius affect PV performance when flexed?

Little has been reported on the effects on PV performance when flexed, so we investigated the effects on J-V parameters when the measurements were performed in 40 mm and 32 mm bend radius, and in a planar state before and after the bend curvature was applied.

Is bending a reversible degradation induced by solar cells?

The degradation induced by bending was irreversible when the sample was reset into planar state . Rance et al. produced CdTe on Corning Willow Glass™ and the solar cells efficiency was measured in the flexed and flat state. It was demonstrated that a bend radius of 51 mm can be achieved without decreasing device performance .
