What is bending test of PV panel?

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).

Does bending test affect photovoltaic characteristics under 40 mm and 32 mm bend radius?

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.

Does bending affect photovoltaic performance?

Our results verify the experimental reports, the η still maintains 95.12 % of the initial value in FPSC when bent to 90°. However, the bending direction generates a huge difference in photovoltaic performance. Bending up is 9.9 % higher than bending down in current density.

What is the mechanical bending performance of FPSC under different curvature radii?

Kim et al. carried out the research on the mechanical bending performance of FPSC under different curvature radii for the first time ( Kim et al., 2015). Even if the bending radius is as low as 1 mm, the η does not be significantly reduced, reaching 93 % of the original value.

How bending experiments are used in PV panels with two boundary conditions?

The bending experiments of PV panels with two boundary conditions are used to verify the accuracy of the proposed solutions. Finally, the influence of different boundary condition is stated by comparing the numerical results and some guides for the PV panel installation are proposed. 1. Introduction

Does FPSC bending performance depend on bending state?

Most research on the bending performance of FPSC has been carried out to evaluate the performance after thousands of mechanical bends but ignore the performance under bending state ( Chang et al., 2015, Chen et al., 2020, Jiang et al., 2021, Park et al., 2017, Wang et al., 2017, Xiong et al., 2018 ).
