Study of a POMA based solar cell

A new type of solar cell based on poly(o-methoxyaniline)-POMA as active lay er is proposed. A simple Schottky structure was prepared: Al/POMA/ITO/glass . The POMA layer was deposited by the casting method and doped with aqueous hydrochloric acid solutions. Light absorption in POMA produces carriers fo r the electrical current. The dark current vs. voltage curves show a rectif ication feature. Under illumination, the short circuit current increases wi th the light intensity, characteristic of the photovoltaic effect. Studies of the dependence on hydrochloric acid concentration, doping time and POMA layer thickness were done. The easy synthesis of POMA and the simplicity of this device are the important aspects of this structure.
