Photoirradiation effects on conductivity in the organic salt α-(BEDT-TTF)<SUB>2</SUB>I<SUB>3</SUB> at temperatures close to the metal–insulator (M–I) phase boundary are investigated using time-resolved measurements of photocurrent. The transient photocurrent at 115 K shows a remarkable persistence at the metallic conductivity and a nonlinear dependence on the light intensity, probably originating from the photoinduced M–I phase conversion in the presence of electric fields.
