A solid-state cell,vas fabricated by sand viching poly[2-methox,-5(2'-ethyl-hexyloxy)-p-phenylene vinylene] (MEH-PPV) in between micro-porous n-TiO2 and p-CuI films. The photo-excited polymer is found inject electrons into the conduction band of n-TiO2 and holes into the valance band of p-Cul. Maximum open-circuit voltage of 400 mV and short-circuit current of about 0.3 mA cm(-2) were observed for the TiO2\MEH-PPV\Cul cell, under white light illumination (100mW cm(-2)).
