โœฆ Synopsis

The sandwich cell, Au/wet poly(viny1 alcohol) (PVA)/merocyanine (MD)/Au, based on the PVA/MD junction exhibited photovoltaic and rectifying effects. Forward dark current from the MD/Au electrode to the counter PVA/Au electrode through the cell was observed. The Au/MD electrode showed a positive photovoltage with respect to the PVA/Au electrode regardless of the direction of the incident light. It was suggested that a heterojunction barrier similar to the Schottky type formed at polymer/dye interface was responsible for the photo charge separation.

The undoping effects of electropolymerized poly (3-methylthiophene) ( PMeT) and poly ( Nmethylpyrrole) ( PMPy ) on the open-circuit photovoltage V0c and on short-circuit photocurrent Jsc were investigated for two-layer organic photovoltaic cells based on the PMeT or PMPylvacuum-evaporated rhodamine
