Abstract

environment temperatures. The most important electrical parameters of the strained cells are extracted as a function of the strain at different temperatures for two conditions: when the cells are under strain and when they are relaxed for 3 min after applying the strain. The only parameter that shows a considerable meaningful change by strain is the series resistance. The final results confirm that the cell with silver electrodes, shows a current increase by tensile strain due to the polymeric chains alignment along the strain direction. But the cell with carbon electrodes experiences a current decrement by increasing the strain. We believe that the carbon electrode, due to the larger carbon Young's modulus, in comparison with the silver electrode cells creates more defect states in the flexible polymeric cells under the same amount of the applied strain. Furthermore, the cell with softer and more stretchable silver grid electrodes can withstand a higher level of strain before suffering any permanent damage.
