Abstract

One use of copper indium dis- elenide (CIS) is in photovoltaic devices. Low-cost films produced by one-step electrodeposition could replace the co-evaporated films used currently if their quality could be improved. It is shown that annealing such CIS films in a selenium atmosphere dramatically improves both their structural properties, as illustrated by the scanning electron micrograph. and electronic properties.
