ANALYSIS OF LIGHT-EMITTING POLYMER ELECTROCHEMICAL-CELLS

Polymer electrochemical cells with ion blocking electrodes were report ed to emit light under applied voltage. This work analyzes the current -voltage relations, internal electric fields, and point defect distrib ution in the polymer. The polymer is regarded as a mixed-ionic-electro nic conductor. Two relevant defect models are investigated, A goad fit is obtained between experimental data and theory which also takes int o consideration electrode over potentials.
