Printed solar cells hold promise for unlit rural areas

[SEOUL] Advances in printed solar cell technology promise clean renewable energy, opening possibilities for 1.3 billion people still without electric power in developing countries.

The technology, which only requires the use of existing industrial-size printers, can produce solar cells that are flexible and inexpensive to transport, says Scott Watkins, director of the overseas business unit of Korean firm Kyung-In Synthetic.

The malleable nature of the paper-thin solar cells makes it ideal for rural communities in remote locations, adds Watkins who spoke at the Smart Villages session of the World Conference of Science Journalists in Seoul, South Korea on Monday (8 June).

Existing solar energy technology consists of silicon-based panels which are produced in wafers and require a large amount of sunlight to be efficient. Printed solar cells employ a more organic approach that uses perovskites, a mineral made out of a precise mixture of lead, iodine and a simple organic component.
