Effects of electrical and thermal stress on polymeric solar cells based on P3HT:PCBM bulk heterojunction

This thesis focuses on polymeric solar cells P3HT:PCBM, particularly on their response to electrical and thermal stress. It starts with the characterization of the cells (IV, short circuit current, open circuit voltage and impedance spectroscopy) and the evaluation of their figures of merit. Next it continues with a series of electrical and thermal stresses and the study of their effects
