An investigation on structure and materials of laminated organic solar cell packaging

Review on mechanical behavior of solar cells for building integrated photovoltaics

“…In addition, the finite element results were compared with four-point bending test results focusing on the effects of different loading rates and cell spacings. The test results showed that the solar cell stiffness increased at high loading rates, and the fracture probability increased when reducing the cell spacing [93]. These authors also verified the finite element results and performed four-point bending experiments under different loading directions and found that the loading directions of solar cells affected the failure probability; loading parallel to the solar cell strips had less influence on the metallization layout than loading in the vertical direction [109].…”

“…The results showed that a reasonable loading direction can improve the loading capacity [92]. Chen et al [93] measured the tensile stress-strain curves of whole organic thin film solar cells and of each layer by conducting tensile tests. The results showed that the elongation at break of the electrode material was quite low (0.2%), which limited the use of the solar cells.…”

“…In contrast, the protection film, the photovoltaic reaction layer and the backsheet material had a certain flexibility because of their good mechanical properties. The maximum stress of the solar cells during the overall tensile tests was 66 MPa, and the elongation at break was 34% [93,94]. For amorphous silicon films prepared on flexible polyimide film substrates, Ding et al [60] measured the tensile strength of the polyimide film by film tensile tests and then performed bending and tensile tests under a scanning electron microscope.…”

Experimental investigation of the mechanical robustness of a commercial module and membrane-printed functional layers for flexible organic solar cells

“…X. Chen and his co-workers investigated the mechanical behaviour of a commercially available OPV product from Konarka Technologies, Inc. through tensile testing [6,7]. With a uniaxial experiment, they obtained the nominal stress-strain curves for the full cell packaging and the individual layers, recorded the fracture sequence of each layer through the test, and showed that the two electrodes present in the stack are the short slab of the cell performance.…”
