The tiny cells could turn a person into a walking solar battery charger if they were fastened to flexible substrates molded around unusual shapes, such as clothing.
Using Solar Powered System may Help to Reduce Emissions in Ships
Japan's largest shipping line are developing a system of solar panels capable of generating 40 kilowatts of electricity for use on a 60,000 ton cargo ship, thus reducing the ship's emissions.

They are expected eventually to be less expensive and have greater efficiencies than current photovoltaic collectors that are pieced together with 6-inch- square solar wafers.
The cells are fabricated using microelectronic and icroelectromechanical systems (MEMS) techniques common to oday's electronic foundries.

According to Sandia field engineer Vipin Gupta, "Photovoltaic modules made from these microsized cells for the rooftops of homes and warehouses could have intelligent controls, inverters and even storage built in at the chip level."
"Such an integrated module could greatly simplify the cumbersome design, bid, permit and grid integration process that our solar technical assistance teams see in the field all the time," he said.
Solar concentrators - low-cost, prefabricated, optically efficient microlens arrays - can be placed directly over each glitter-sized cell to increase the number of photons arriving to be converted via the photovoltaic effect into electrons.
The small cell size means that cheaper and more efficient short focal length microlens arrays can be fabricated for this purpose.
