The strength information of bending tests of solar cells can be used to analyze the breakage of solar cells in modules in more detail in order to reach a more comprehensive understanding of failure mechanisms in solar cells.
The bending test of PV panel is performed at room temperature to verify the structural analysis results aforementioned and detect the real mechanical properties. The 6 specimens are all the double glass photovoltaic modules (as shown in Fig. 9) which are provided by Suzhou Tenghui Photovoltaic Technology Co., Ltd (Changshu, P.R. China).
A mechanical simulation model is presented which can be used for evaluating stresses in 4-point bending tests for solar cells with standard concept (Al-BSF, H-pattern). It is shown that the layered structure can be considered but has only minor influence on stiffness and stress distribution of the solar cells compared to a pure silicon wafer.
The error bars are the standard deviation of the 8 solar cells. In addition, a static 32 mm bending test was performed for 168 h ( Fig. 4 ). The J-V was measured before and after bending and in 32 mm bend radius at 0, 24, 48, 120, 144 and 168 h.
Importantly, the bending tests are a primary metric for mechanical robustness, and the recommendations in this Perspective provide a fundamental starting point for the systematic characterization of mechanical device performance in PV cells.
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.
