Abstract

We have fabricated a rechargeable photo-chemical battery using ion-hole conducting AgAsS₂ films. An asymmetrically-electroded Al/AgAsS ₂/SnO₂ yields photocurrents and upon illumination it is concomitantly charged up. When the illumination is stopped, the stack discharges electricity into an external circuit. This photo-charging and discharging phenomenon is attributed to a photo-chemical modification of Ag-ion distribution in amorphous AgAsS₂.
