Photovoltaic and I-V Studies of the Nonconjugated Polymer 6FPBO-OD
Abstract
6FPBO-OD has been shown to be a viable candidate for blue LED’s. That success prompted the investigation of the complimentary photovoltaic properties of this polymeric system. Photovoltaic spectra have been measured under various bias conditions and after I-V experiments using lock-in techniques. The amplitude of the spectra could be diminished by exposing the sample to continuous light of energy higher than the band gap during the experiment. The current-voltage behavior of single layer LED structures of 6FPBO-OD has been measured in both the dark and under illumination. Significant hysteresis occurred in illuminated cyclic I-V measurements. When illuminated with white light, open circuit voltages in excess of a volt have been observed. The I-V data showed an order of magnitude increase in the current through the device under illumination. However the short-circuit current was very small when compared to commercial photovoltaic devices.
