Effective solar cell device definitly has great application in any electronic products that require power supply. Inorganic semiconductors like Si currently rule the market. Organic materials potentially have advantage of smaller size (thinner), light weight, effcient, flexible (bend without breaking), and low cost. Many experts, and labs bet the future of photovotaics (PV) on organic materials.
US Dept. of Defence may be the biggest investor in this technology. Lynne Samuelson, a researcher at the US Army's Natick Soldier Center, in Massachusetts, claimed that his lab is starting to make proto-type PV devices to try out in the field. That Lab teamed up with a chemistry lab at Univ. of Massachusetts Lowell. The structure and materials used in their cell may contain Titania (? it may mean Ti)-TiO2 particles/Polymer. Titania particle can be as small as 20nm. The polymer is polyethylene terephthalate. Its effciency has not been disclosed. It is estimated that it may be >4%. This lab is expecting 20% effciency in five years.
